Maritime transport: Practical guide to shipment of goods

Maritime transport is the backbone of international trade. In fact, in Spain it accounts for around 80% of imports and approximately 50% of exports.

Complying with the specifications of maritime shipments is crucial to ensure that our merchandise arrives at its destination in a timely manner. Therefore, if your company is involved in exporting or is considering doing so, it is important to understand the factors that affect ocean shipments and what types of packaging are most suitable for this type of transport.

 

Factors that condition maritime transport

One of the advantages of maritime transport is its versatility, since it adapts to any type of cargo. However, there are issues that must be taken into account when preparing our shipments:

Maritime transport Practical guide to shipment of goods

Type of container:

Most of the international transport of dry goods travels by container. Depending on the cargo, a type of container will be chosen and also whether it will occupy a full container (Full Container Load or FCL) or share space with goods from other exporters (Less Than Container or LCL).

Sudden abrupt movement:

Containers may experience sudden movements during handling and due to sea conditions, which may affect the stability of the cargo.

Temperature:

Temperature changes may occur during voyages, affecting the cargo.

Humidity and salinity:

Sea salt and humidity can cause the cargo to rust.

How to protect the goods for maritime transport?

Considering the peculiarities of maritime transport, it is time to analyze which packaging will help us to avoid damage or loss, and ensure a correct transport of the cargo from its origin to its destination.

 

  1. Fastening systems

For sensitive cargo, such as electronic equipment or chemical products, it is important to use securing systems to immobilize and secure the cargo inside the container.

In this regard, airbags are one of the most effective devices. These airbags are placed between the packages and prevent their movement. They are reusable and adapt to the irregularities of the cargo.

2. Insulating systems

For goods sensitive to humidity and salinity, such as metal parts without surface treatment or electrical equipment, insulating systems can be used to keep the atmosphere as neutral as possible during transport.

Among the isothermal insulating systems, heat-sealable bags stand out. They are a product widely used in packaging to prevent corrosion, especially in the case of metal and electronic devices. As a complement, dehydration systems such as desiccant salts are used to absorb moisture from the internal air volume. Moisture detectors will indicate whether the desiccant salts have reached their absorption capacity limit.

We also manufacture customized heat sealable bags; you can see the video here:

 

Shrink-wrapped plastic is used for large-volume cargo or machinery. This type of plastic creates a protective film against adverse weather conditions (UV rays, rain, wind).

3. Phytosanitary certification and sealing ISPM-15

In international transport, all packaging with wood as raw material must bear the corresponding marking, complying with the International Standard on Phytosanitary Measures ISPM-15. This regulation serves to prevent the spread of pests.

However, the certificate will depend on the geographical location to which the cargo is destined and whether it is required by the plant protection agency of the destination country. For example, for exports to European Union countries the standard is not mandatory, but in certain cases they may request the ISPM-15 marking.

Among wooden packaging, a very widespread solution for maritime shipments is the Clipping Crate ®. This is a reusable, economical, resistant box with an innovative design. It is equipped with a closing system using galvanized zinc clips or staples, which provide strength and flexibility. In this way, the box can be assembled and disassembled by a single person without the use of tools. A very useful system that facilitates customs inspection.

Pharmaceutical product Packaging

Pharmaceutical packaging plays a fundamental role in the protection of medicines during storage and transport. Tablets, syrups, ampoules, vaccines… Everything must be packaged in compliance with strict safety requirements so that they reach the patient in optimum conditions.

In addition, the way in which medicines are administered determines the design of the packaging, which must facilitate opening and dosing.

 

Pharmaceutical packaging regulations

Pharmaceutical packaging is regulated by different regulations aimed at ensuring the safety and efficacy of medicines, as well as the protection of people and the environment.

In Europe, Directive 2001/83/EC determines the information, packaging and labeling that medicinal products must carry. There are also specific rules governing other aspects, such as protection against counterfeit medicines (Directive 2011/62/EU of the European Parliament and of the Council) and waste management (Directive 2008/98/EC of the European Parliament and of the Council).

Types of pharmaceutical packaging

The most common types of packaging in the pharmaceutical sector are:

Blister:

Consists of a plastic or aluminum foil containing the drug, allowing its administration in doses such as tablets, individual capsules, dragees, etc.

Bottle:

Made of glass or plastic, used for the storage of liquids and solids.

Pharmaceutical product Packaging

Which packaging is the most suitable for the pharmaceutical sector?

Pharmaceutical products are a delicate type of goods, which require special control conditions during the whole packaging process. Therefore, a pharmaceutical packaging must be able to keep the medicines intact throughout the entire supply chain.

For example, using opaque materials that protect it from light, that act as a barrier to water vapor and oxygen, and with a correct sealing and immobilization that prevents degradation or overturning of the product.

In this sense, corrugated cardboard boxes on wooden or cardboard pallets are an interesting option, because they are suitable for both storage and transport of this type of merchandise.

They are also compatible with the standardized European and American palletizing systems and, as they are certified with the ISPM -15 phytosanitary seal, they are suitable for export.

In addition, auxiliary fastening systems such as strapping help to keep the goods securely fastened. Likewise, desiccant salts absorb the humidity inside the packaging during transit.

Pharmaceutical product Packaging

Sustainable pharmaceutical packaging

Pharmaceutical packaging is constantly evolving. Innovation, sustainability and safety set the trends in the sector.

Environmental impact is another of the challenges facing the industry. In the area of primary packaging, the first steps are being taken in the manufacture of recyclable paper blister packs.

Regarding secondary and tertiary packaging, 360 Eco Packaging has been developing sustainable packaging for years, using reusable and recyclable materials. All this together with an optimization service aimed at helping companies implement more efficient logistics, with lower energy consumption and less impact on nature.

Main packaging certifications

Certifications are key indicators in any activity. Through these accreditations, packaging manufacturers can demonstrate that their products or services comply with the regulations required by transport agreements, and at the same time meet high standards of safety, quality or environmental responsibility. They are, therefore, a guarantee of how we do things.

ISO 9001 certification is one of the most widely implemented standards among companies. In our case, this seal accredits the quality of our processes for the design and manufacture of industrial packaging.

In the packaging field there are other valuable rules and certifications that we highlight below:

Phytosanitary-certified wood packaging material

The International Standard for Phytosanitary Measures ISPM-15 was created by FAO to regulate wood packaging in international trade in order to reduce the risk of introduction and spread of pests.

The ISPM 15 seal is based on a heat treatment that consists of the wood reaching 56 ºC in its core for at least 30 continuous minutes.

       Once the wood has been treated, the mark must be visible on at least two opposite sides of the wood.

The ISPM-15 standard affects packaging made wholly or partially from raw wood, such as pallets, crates, crates, crates, crates, dunnage, pallets, cable drums and reels. Plywood is excluded.

To obtain the ISPM-15 label, it is necessary to be registered in the national system and to pass the required annual audits, through the control of the traceability of the manufactured elements.

The issuance of a certificate will only be necessary if required by the phytosanitary protection agencies of the destination countries.

ISPM15

Certified Dangerous Goods Packaging

Dangerous goods are considered to be solid, liquid or powdered products that represent a risk to the safety and health of people or the environment.

The transport of dangerous goods requires specific approved packaging, with its corresponding certificate in accordance with the regulations of each mode of transport. The regulation par excellence in the transport of dangerous goods by road is the ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road).

Compliance is also mandatory:

  • Rail RID (Regulations concerning the International Carriage of Dangerous Goods by Rail).
  • Air transport IATA (International Air Transport Association).
  • Maritime transport IMDG (International Maritime Dangerous Goods Code).

The UN has established a universal system of classification, packaging, marking and labeling of the different dangerous goods valid for all modes of transport.

Dangerous goods packaging can be made of plastic, cardboard or metal, but must always be properly labeled. In addition to the labeling required for each type of goods, according to its classification in the ADR, each package must show a UN number, among other data such as the manufacturer’s code, type of box, password, country and year of manufacture.

The ADR defines packing instructions for each UN number, according to which the physical-chemical specifications that the packaging must meet for a given good will be detailed.

Packaging with PEFC / FSC® certification

Nowadays, it is impossible to talk about quality without taking environmental criteria into account. PEFC and FSC® chain-of-custody certification guarantees good practices along the entire wood value chain.

PEFC-certified pallets, wooden crates and cardboard boxes use raw material from sustainable logging, recycled material or both. Choosing PEFC / FSC® certified packaging means promoting a responsible supply chain, contributing to sustainable forest management and the well-being of forest communities.

FSC

These seals are also a competitive advantage in markets that require the supply of environmentally responsible materials.

Securing loads with Airbags

When determining the right packaging, many aspects must be taken into account. One of them is the fixation and adjustment of loads. For this purpose, multiple systems and pneumatic elements are used to ensure that our shipment arrives in optimal conditions.

One of the most commonly used are dunnage bags or airbags for packaging.

Securing loads with Airbags

What are packaging airbags?

Packaging airbags, dunnage bags or inflatable bags are used to protect goods during transport. Their function is to fill the empty spaces between the cargo or between the cargo and the walls of the transport unit, keeping it immobile in order to reduce the possibility of damage during transport.

These bags are very easy to use. They are filled with air through a valve to the required pressure. Airbags are available in different sizes, depending on the use and load.

Securing loads with Airbags

Which airbag do I need to protect my cargo?

Airbags can be used in land, sea or rail transport. To know what type of airbag we will need, the first thing we must know is the volume and weight of the cargo to be transported (to define the working pressure of the airbag), as well as the operating time of this airbag. Once these parameters have been set, we will check the manufacturer’s technical data sheet to see if it adapts to our needs.

Most manufacturers comply with the AAR Bulletin No. 9 (Association of American Railroads), the most widespread international standard, which classifies these pneumatic elements into 5 levels, according to the type of transport and the operating pressure.

Securing loads with Airbags

As shown in the table, the different types of transport are classified according to the working pressure. This is because this standard contemplates pressure tests after 19 days, allowing a load loss of no more than 1psi. In other words, for long transports we must generally use level 2 airbags or higher (more working pressure).

Once we have defined the type of air bag we need, we will have to design a system of loads as homogeneous as possible, using these elements to adjust the loads.

To do this, we can take into account the guidelines of the CTU 2014 code, which, among other issues, details the different misuses that can occur when applying this system.

Securing loads with Airbags

Types of airbags and characteristics

They can be made of different materials, depending on their resistance to external agents in case of possible rupture.

There are basically two types, depending on the material they are made of:

  • Raffia:

These are bags or sacks consisting of an inner layer of polyethylene and a top layer of raffia, a type of elastic fabric widely used for packaging due to its resistance.

  • Kraft paper:

They have an inner layer of polyethylene and a top layer of Kraft paper reinforced with polypropylene to prevent tearing.

In both cases, they are durable, reusable and waterproof, providing an efficient solution to protect cargo during transportation.

 

If you need advice, consult a reliable supplier to help you choose the best option.

What is Just in Time logistics?

The world is constantly evolving. The changes that are taking place have an impact on supply chains. Industrial packaging manufacturers have to respond to the challenges posed by different logistical operations, however complex they may be, in times of greater or lesser uncertainty.

One of them is Just In Time manufacturing, which orients production to demand.

What is the Just in Time method?

The Just in Time production method is based on real orders. It consists of producing the exact amount of what is required, in the right place at the right time, without wasting system resources.

Just in Time logistics

Its origin comes from Japan. In the mid-twentieth century, large Japanese companies were looking for more efficient production systems, which in turn would allow them to reduce factory inventory. Toyota was the first company to apply the Just in Time method, under the name of Toyota Production System, in automobile manufacturing plants, with the aim of eliminating from the production process those elements that did not provide real value.

Since then, automotive companies, technology companies, fast food chains around the world and today, e-commerce companies use this model to make their processes more efficient, optimize costs and respond better and faster to customers.

Just in Time logistics

What are the advantages and disadvantages of the Just in Time method in logistics?

  • Zero defects: an error can cause delays and increase stocks.
  • Zero breakdowns: this implies scheduled maintenance of work tools.
  • Zero stocks: this generates storage and space costs.
  • Zero lead times: reducing production cycles reduces waiting times, equipment preparation and transit times.
  • Zero paperwork: reducing bureaucracy to a minimum.

Applying this method provides better management, greater flexibility and savings, but requires millimetric coordination in all the links that make up the supply chain.

Just in Time logistics

Advantages of JIT

  • Reduces inventory levels and costs associated with purchasing and warehousing, since only what is in demand is manufactured.
  • Minimizes losses, obsolete products, expired products or products that lose value when stored, by having a minimum stock.
  • Reduces time and unnecessary trips to locate the merchandise.
  • It favors a closer relationship with suppliers.

 

Disadvantages of JIT

  • Possible delays and lack of supplies.
  • Less access to special prices for small-scale purchases.
  • Increased costs when changing suppliers.
  • Scarce capacity to react to demand peaks.
Just in Time logistics

Packaging for Just in Time logistics

As with all other supplies, packaging in JIT operations must be available when it is needed. Companies specializing in this type of packaging must be able to offer packaging solutions that help simplify operations and speed up delivery times, that are easy to handle and help reduce storage costs.

This logistics requires ergonomic packaging, which allows assembly/disassembly in a very simple and safe way, folding solutions, which facilitate internal movements and save space, as well as customized packaging, which optimizes the logistics process to the maximum.

Packing for moving

Nobody is aware of what they have until they have to move, that is why in this post we will talk about packing for moving. Moving our belongings from one place to another requires good planning, starting with choosing the optimal packaging so that the move is resolved quickly and smoothly.

Like any other type of shipment, each move will require different packaging, depending on the contents to be transported and the mode of transport.

Packing for moving

What is the most suitable packing for a move?

The packaging systems for the moving or furniture storage sector share the following characteristics:

Packing for moving

Types of packaging for moving

No two moves are the same. Moving a house is not the same as moving an office where electronic equipment and components are moved, much less a transoceanic move in a container.

Depending on the volume of material to be transported, wooden, cardboard or cardboard combined with wood packaging solutions can be used.

The most common are:

Cardboard boxes

Cardboard boxes are the most common type of packaging used in removals. As is logical, boxes of different sizes are used, depending on the needs. From a weight of 8 kilos upwards, it is advisable to use two-channel cardboard boxes, which offer greater resistance and protection.

Large-volume cardboard boxes, available with flaps or lids, are used to move large furniture and belongings.

Packing for moving

Folding wooden boxes

Plywood transport crates with lids are the most commonly used for transoceanic moves. This type of box is made of ISPM15 certified wood, so it is suitable for international shipments.

It is a reusable, stackable and collapsible box. It consists of a lid, a base with support and a very consistent central body. The anchorage of the pieces is by means of metallic tabs, which gives it great resistance.

Packing for moving

Fillings to protect the inside of the boxes

Just as important as choosing the most suitable box for a move is to have protection and padding aids to protect the contents inside.

Packing padding products immobilize objects to prevent them from suffering any impact during transportation and protect them from humidity or vibrations so that they arrive at their destination in perfect condition.

An economical solution to protect ceramic pieces, glassware or fragile products, as well as to fill the gaps left in boxes, is cardboard netting.

Cardboard corner protectors and foam profiles are essential to protect the edges on the inside and outside of the boxes.

In international moves, and especially in sea transport, inflatable bags or airbags are used as a complementary system in cargo lashing to fill the gaps in containers and prevent them from moving.

7 milestones in the history of packaging

Since ancient times man has had the need to protect his belongings, hence the following post on the history of packaging and its evolution.

Over the years the evolution of the history of packaging has been parallel to the economic and social development of the time. As manufacturers of industrial packaging, these are for us the 7 most important milestones in the history of packaging.

1. From clay to wood for transporting wine

In ancient Rome, large clay containers were already used to store and transport wine. The clay amphorae and jars were airtight and protected the wine from oxidation. Upon conquering French lands, the Roman Empire discovered the wooden barrel; an easy-to-handle container, lighter and more consistent than clay for transporting wine from Greece, Gaul and Hispania.

This was the way it was done for centuries until glass arrived. In the 17th century the use of the bottle became widespread. However, wood continued to be a highly valued packaging in the logistics of the wine sector.

 2. The emergence of corrugated cardboard

The Chinese are considered to be the first to use corrugated cardboard in the 16th century. However, it was the pleats of Victorian fashion in the mid-19th century that led to the development of corrugated cardboard.

In 1856 Healy and Allen patented in England the use of pleated paper as an inner reinforcement for stiff top hats. Years later, the American pharmacist A. Jones came up with the idea of wrapping fries in corrugated cardboard. Jones came up with the idea of wrapping perfume bottles in corrugated paper to protect them from knocks.

In 1874, Oliver Long improved Jones’ patent by adhering the corrugated paper to a flat sheet of paper and then to two flat sheets of paper. Liners were born, the structure of corrugated cardboard that provides the compression and strength of the cardboard boxes we use today.

In 1890 Robert Gair invented the corrugated box and the American Thompson and Norris Co. began manufacturing the first boxes.

Today the cardboard box is the preferred packaging for ecommerce due to its lightness, strength and low cost.

Corrugated cardboard

3. The arrival of the europallet

It was not until World War II that the use of pallets became popular for moving military equipment. Until then, wooden crates, skids or barrels were used to move the goods.

At the end of the war, the first American pallet patents were registered. However, train wagons in Europe had dimensions in which they did not fit well, so it was necessary to reduce them and regulate their manufacture so that they all had the same dimensions and could make better use of space. In the 60’s the Euro pallet was born.

Since 1991 the European Pallet Association (EPAL) issues licenses to manufacturers and under the EPAL seal certifies the quality of the pallet and identifies reliable suppliers.

European Pallets EPAL

4. The collapsible wooden box, a step towards packaging engineering

During World War II, the Allied side had to make a great logistical effort to get weapons, equipment and medical supplies by ship and plane to the places in conflict. One of the biggest challenges was shipping war vehicles.

The Jeep automobile company had designed the “Willys,” an agile and rugged all-terrain vehicle, the forerunner of the 4×4 we know today. For domestic shipments, vehicles were stacked on top of each other on pallets. But shipping them across the ocean required special packaging. And an innovative solution was found: the disassemblable wooden crate.

The “Willys” was stored in pieces and once at destination the crate was disassembled, allowing access to the vehicle and assembly in a matter of minutes.

Today, packaging engineering continues to successfully meet the challenges of the automotive sector.

5. The expansion of plastic

The origin of plastic is related to the game of billiards. An American company decided to award 10,000 dollars to whoever could create a material to replace ivory, which was scarce at the time, to manufacture billiard balls. In 1870, the Hyatt brothers chemically modified cellulose to produce celluloid, winning the contest and obtaining the first plastic in history.

In 1907, Baekeland invented Bakelite, the first fully synthetic commercial plastic, described as thermosetting, insulating and resistant to water, acids and moderate heat. In the following decades, new plastics derived from the processing of fossil fuels, such as polyethylene or polyvinyl chloride (PVC), were investigated.

At present, the applications of plastic are infinite, and it is a very common material in the manufacture of returnable containers and packaging for industrial use.

Plastic collapsible crate

6. The box that revolutionized the transport of goods: the sea container.

Since they made the first transatlantic crossing in the mid-twentieth century, sea containers have revolutionized the transport of goods. Before their appearance, ships were loaded manually, which meant long waits in port.

The businessman Malcolm McClean came up with a system whereby cargo could be stacked inside a large metal box and transported by ship or truck. Thus was born the container, which made its first trip in 1956, from New Jersey to Houston.

A decade after its first trip, the ISO (International Standard Organization) developed standards for its international use. Containerization led to a reduction in the cost and time of freight transport, giving way to intermodality.

7 milestones in the history of packaging

7. Ecopackaging and sustainable packaging

In the mid-twentieth century the packaging industry began its development and today continues to evolve.

With self-service, marketing, the computer and the internet, packaging began to spread, becoming a competitive advantage for companies and a lure for the consumer.

 

Foldable wooden crate

Today, the Circular Economy model and the preferences of an increasingly eco-conscious consumer force the industry to look for sustainable packaging solutions, designed from the source to reduce the use of resources and revalue their waste, without forgetting their original purpose: to protect the goods.

Bubble Wrap

In today’s post we will develop a very employed element in packaging, the alveolar film, more commonly known as bubble wrap.

This type of film can be used in the packaging of fragile and small objects, such as the packaging of parts for industrial use, as well as insulation in sectors such as construction.

This type of film is a transparent and flexible material, composed of polyethylene plastic sheets joined together by mechanical-thermal methods, which allows the formation of air bubbles, its main characteristic, these bubbles provide excellent cushioning and insulating properties.

Bubble Wrap

Types of bubble film

 

2-layer bubble film or Simple:

This type of bubble film is composed of only two sheets of polyethylene, which makes its manufacturing process very simple.

The first film or layer used passes through a perforated cylinder that suctions it by pressure, then it is sealed with the second layer by means of heat, which creates air bubbles.

Bubble Wrap
Bubble Wrap

3-layer bubble film or Closed:

The 3-layer or closed bubble film is made of 3 polyethylene sheets, which makes it more resistant than the simple film.

The creation process has few differences with respect to the simple film, the fundamental difference, as its name suggests, is that a third sheet of polyethylene is added on top, creating a sort of second bubble that cushions impacts, which makes this type of plastic more resistant and improves its properties.

Bubble Wrap

Characteristics of bubble film

 Thickness:

Bubble film can be presented in different thicknesses measured in grams per m2

Thickness – Bubble Type

30g/m2 – Very thin bubble, more economical.

40g/m2 – Commercial bubble

50g/m2 – Standard bubble wrap and highly recommended for all packaging uses.

60g/m2 – Strong bubbles, professional use.

70g/m2 – Very strong and resistant bubble paper.

more than 80 – Extra strong, not very common in packaging.

 

Laminate:

Bubble Wrap
Bubble Wrap

How to use bubble film

One of the most common questions when packaging products with bubble film is the arrangement of the bubbles, that is, whether to put the bubble inside or outside.

We may think that it is indifferent since the order of the factors does not alter the product, but it is not.

Below, we show you two photos with two boxes packed with bubble film, one of them with the bubble facing outwards and the other facing inwards.

As we can see in the first photo in which the bubble is facing outwards, between bubble and bubble we are only protecting our product with a thin layer of flat polyethylene film, which makes the protection decreases considerably, on the other hand, the bubbles are exposed to all kinds of blows, scratches etc. and could be easily punctured.

If we look at the second photo in which the bubble film is with the bubble facing inwards, we can see that the object is completely protected and the bubbles do not run the risk of being punctured.

 

If we use triple-layer bubble film in our pack6aging, we would not have any of these problems, since by creating a second bubble it makes no difference how the film is placed, because a flat surface will always appear on top, with the bubbles placed underneath, which means that they are protected. The use of this type of film would have a higher cost, since it has a more complex manufacturing process.

 

As a final conclusion and after analyzing the honeycomb film in detail, we can see the number of possibilities offered by a product so commonly used in both industrial and domestic use, so depending on our needs we must analyze what type of film or what characteristics it should have to obtain the best results.

Wrapping up our journey through the fascinating world of bubble wrap, we hope you have discovered its importance and versatility in protecting our precious belongings.

As we reflect on the need to reduce environmental impact, let us also remember the value of reusing and recycling this material to minimize its ecological footprint. Let’s continue working together towards a sustainable future!

Aluminium Foil Barrier

The Heat-Sealable bag, Insulating bag or Aluminium Foil barrier material is a widely used element in packaging to prevent corrosion, especially when it comes to metal packaging and electronic items.

Aluminium Foil Barrier

It is used in conjunction with desiccant salts precisely to prevent moisture from oxidizing the metal on long ship voyages, but is also used for long-term protection of machinery and other products, for example, for storage if long-term storage is planned.

 

 

COMPOSITION

This material is mainly composed of aluminum and polyethylene. Depending on the manufacturer, the proportion of each material and even the type of plastic used may vary. For example, sometimes polyester, PET plastic or polypropylene are added. As for polyethylene, it can be of high or low density.

Some barrier materials have more plastic than aluminum or vice versa. The quality and correct protection of the product will depend to a large extent on the total thickness of the barrier film from which the bags are made and how many grams it weighs per square meter, as well as the proportion of aluminum it contains. The more aluminum the material contains to the detriment of plastic, the lower the vapor transmission inside the container.

This material is waterproof and resistant to external factors such as ultraviolet rays.

 

PRESENTATION

Generally we can find this material in rolls whose measures can vary according to the customer’s needs, although it is also common to find manufacturers and companies that sell ready-made bags with the measures that the customer deems appropriate.

Aluminium Foil Barrier

The aluminium foil barrier bag can also be vacuum sealed if desired, with the help of special machines that absorb oxygen from inside the bag. In this way, the product is better protected against oxidation.

There are several ways of sealing this bag. As its name suggests, the most common way is with heat, although we can also opt for plastic closures that seal the container.

This material can also be printed, so it is common for a company to print its own corporate logo, as well as the specifications of the material and the temperature to which it must be subjected for sealing.

This material must be manufactured in compliance with DIN 55531-1, which is the German and European standard in general.

 

Other world standards equivalent to this norm that can be found are the following:

  • USA: MIL-B-131.
  • France: NF H 00310.
  • Germany (military classification): TL 8135-0003.
  • United Kingdom (military classification): DEF STAN 81-75/1.
Aluminium Foil Barrier

To conclude, it is convenient to point out the main difference between aluminum barrier material and other plastic materials that we will see later, such as shrink film or VCI. For long boat trips, adverse weather conditions or long storage periods, aluminum is the most convenient option for the correct protection of the product against plastic compounds, since it is much more resistant.

Case study, Use of Desiccant Salts

In the previous post we have seen what a DIN unit is and the degree of absorption per unit, therefore we must remember that a DIN unit is equivalent to an absorption of 6g of water and that to absorb these 6g of water approximately 30g of desiccant salts are necessary (depending on the type of salt and the conditions).

Desiccant Salts

Having recalled the previous post, we consider a practical case for a part of dimensions 1150x750x750mm (length x width x height) to be transported in a box equipped with a thermoweldable bag of inner dimensions 1200x800x800mm.

 

To calculate the volume of air enclosed between the box and the part we must find the differential of volumes, therefore:

 

1,2 x 0,8 x 0,8 – 1,15 x 0,75 x 0,75  = 0,121 m3

 

Once this data has been calculated, we go to the formula:

 

n = 1/a · ( V · b + m · c + A · e · D · t )

And we calculate the number “n” of DIN units replacing each constant by its value, (to know the value of these parameters do not hesitate to visit our previous post).

The result would be n = 2 approximately, so about 60g of desiccant compound would be necessary for this packaging. We must bear in mind that it is always better to distribute these salts proportionally so that the atmosphere always maintains homogeneous humidity levels, so whenever possible we will use several bags distributed homogeneously.

Desiccant Salts

As we have mentioned in previous posts, it is important to define the volume of air that we want to maintain with low humidity levels in order to calculate the number of DIN units that will be necessary. Once we know this information, our supplier will tell us the exact grams of salt that we will need depending on its composition.
