How to Retract a Merchandise

Post by 360 Ecopackaging On 0 Comments

The shrink wrapping of goods is a process used to secure and protect products during transport or prolonged storage.

This type of plastic creates a protective film capable of protecting items against adverse atmospheric conditions (UV rays, rain, wind…).

 

Materials needed for shrink wrapping

Below, we provide you with the necessary materials to shrink wrap effectively:

Steps to follow to shrink-wrap goods

 

Prepare the load: the first step is to place the products in an organized way, making sure that they are well secured and that they do not move.

Cut the shrink wrap: next, cut the necessary amount of shrink wrap to completely cover the load. It is important that the shrink wrap is long enough to seal the bottom of the pallet.

Place the shrink wrap over the load: once the shrink wrap is cut, unfold it over the load and check that it is completely covered. If it is not well covered, adjust its position.

Seal the plastic at the bottom: with the help of the clamp, seal the plastic to the bottom of the load, so that it is taut and tight, to avoid wrinkles or air pockets.

Apply heat: in this step, repeat the same process as in the previous procedure, but this time it is done on the load. Again, it is important to avoid possible wrinkles or air pockets.

Finish shrink-wrapping: the last step is to check that there are no gaps or goods exposed to the elements. In case of an error, this piece should be covered with more plastic or with specific adhesive tape.

Mechanical Impact Detectors

Post by 360 Ecopackaging On 0 Comments

There are two types of impact detectors: mechanical and electronic.

This time we will focus on mechanical devices, they are the most used and the most affordable due to their simple architecture. They are capable of detecting impacts on one or more axes and there are tared models with different g-force sensitivities.

Mechanical Impact Detectors

Therefore, we can classify these detectors as:

 

One-dimensional

Mechanical detectors that capture accelerations in only one axis (one direction and two directions).

These detectors are the most commonly used, there are sticker type (with adhesive) that are easily anchored to the packaging to be controlled.

Mechanical Impact Detectors

Their placement is generally:

  1. For a box with a side-to-side proportionality of approximately 1:1
Mechanical Impact Detectors

2. For a box with approximate side-to-side ratio > 2:1

Mechanical Impact Detectors

3. The heights “h” at which the indicator should be positioned may vary depending on the load, the g-force and the manufacturer.

Most of these indicators are activated by changing color (red) when the maximum set acceleration has been exceeded, it does not show a history of events, for that an electronic detector would be necessary.

 

Two-dimensional

 

Mechanical detectors that capture accelerations in two axes (two directions with their two senses).

These detectors are capable of detecting impacts in two directions and even show the direction, sense and modulus of the maximum force to which the load was subjected as shown in the above simulation (provided it is within the operating range of the detector).

Mechanical Impact Detectors

Their placement is generally done by means of four screws (per detector) and unlike the one-dimensional ones, their location in the case does not generally interfere in the operation.

There are two main types: magnetic and combined sphere-spring system.

Both are two-dimensional and allow the working accelerations g to be adjusted (depending on their type of construction).

Cardboard, a strategic packaging for the Circular Economy

Post by 360 Ecopackaging On 0 Comments

In a Circular Economy model where waste becomes a resource, the paper and board industry has a key role to play.

 

We know that the future of packaging involves incorporating sustainable materials, reducing the ecological footprint associated with its production and use, and that its waste can be revalued, without neglecting the purpose for which it is designed: to protect the product. In this future, cartonboard packaging will be a priority.

 

Cardboard as a sustainable packaging material

 

Cardboard is a natural, renewable, recyclable and biodegradable material. In recent years, it has been replacing other traditional packaging materials such as plastic.

Paper and cardboard fibers are also much stronger than previously thought. It has been shown that fiber-based packaging material – paper, cardboard, paperboard and folding cartons – can be recycled more than 25 times, retaining their mechanical properties for re-integration into the production process.

This makes it one of the most sustainable materials in the packaging sector and one of the preferred packaging solutions for the consumer.

Cardboard, a strategic packaging for the Circular Economy

Why is cardboard packaging preferred by consumers?

 

The way companies package their products is a matter of concern for consumers, influencing their purchasing decisions.

The European Association of Carton and Cartonboard Manufacturers reveals that 4 out of 5 consumers prefer cartons to plastic. In its report, it says that more than half of the consumers surveyed in Spain claim to have switched brands because the packaging was not recyclable or because they used unnecessary packaging. It adds that 82 percent would be willing to pay more for environmentally friendly packaging.

Most commonly used carton packaging

For companies interested in incorporating circularity into their packaging, cardboard packaging represents a zero-waste system of significant social, economic and environmental value.

Because of its versatility, it can be used throughout the packaging chain:

  1. Primary packaging, which is directly in contact with the product.

  2. Packaging for Ecommerce.

  3. Cargo units for storage and transport of consumer goods.

  4. Protective elements, such as interior fillers to pack merchandise shipments, or corners to avoid friction during transport.

The most commonly used cartons are:

Corrugated cardboard boxes

Can be used in standard size or large volume for packing and palletizing light and heavy goods. They are foldable, which facilitates storage, reducing space.

 

Pallet boxes

They are corrugated cardboard boxes placed on a wooden pallet or cardboard. Its use as commercial exhibitors has been extended by its profitability, since they serve both as product container shelf and advertising support, because the cardboard can be easily printed and incorporate gaps or shelves to place the product.

 

The cardboard pallet

Consists of corrugated cardboard sheets and solid cardboard blocks that are inserted as pillars. Resistant and lighter than the wooden pallet, it is also valid for international transport, without having to undergo phytosanitary treatment.

 

The road map to a Circular Economy is written on cardboard.

Desiccant/Dehydrating salts

Desiccant Salts

Post by 360 Ecopackaging On 0 Comments

Desiccant salts, also called dehydrating salts, are chemical compounds that absorb moisture and water in very different ratios, depending on the amount of desiccants and their chemical composition, and can regenerate if subjected to a temperature above 150ºC.

There are different types of desiccant, the most common are:

 

  • Silica gel

These are small solid pellets of silicon dioxide obtained from sodium silicate. Despite being a chemical compound, it is not toxic or flammable by itself, although one of its components is highly toxic to humans if ingested or in contact with it for a long time, as it could cause silicosis. This is cobalt chloride, which is used to determine the amount of moisture in the gel. In this way, it causes the gel to change color when wet, varying from blue (dry) to pink.

Desiccant Salts

  • Bentonite

Is a very fine-grained (colloidal) clay of the montmorillonite type containing bases and iron. The name derives from a deposit found at Fort Benton, USA. The particle size is less than 0.03% of the average grain size of kaolinite.

Desiccant Salts

  • Calcium chloride

In addition to its use in pharmaceuticals and food, this compound is used as a desiccant, given its moisture-absorbing qualities. It is less common than silica gel, although it does not contain toxic elements and has a higher degree of moisture absorption. The problem is that it is not advisable to use it in spaces that are not hermetically sealed, since it runs the risk of liquefying, with the consequent elimination of its absorption capacity.

Desiccant Salts

Measures

 

There are four different units for measuring desiccants. The most commonly used due to their standardization are grams, but we also find NFH, DIN units and MIL units.

These would be the equivalences between them, taking as a reference the most used measurements:

Equivalency table

We recommend the use of one half kilo bag (16 DIN units) of desiccant or dehydrating salts per cubic meter. As a guideline, we can indicate that for a 20 feet container it is advisable to use 20 bags of 1 kg. These data are estimates since, depending on the cargo to be transported (sensitivity to oxidation and/or corrosion mainly), the proportion of salts should be adjusted to maintain the relative humidity at the established rates.

 

Packaging

 

The desiccant can be purchased in bulk or packaged in breathable bags for use in containers or inside packaging.

The bags are made of non-woven textile so that moisture passes through them and can be picked up by the compound. Now, certain desiccant manufacturers have begun using another material called Tyvek, which is used primarily in home and building construction to prevent moisture.

This material is made of high-density polyethylene and nonwoven olefin fiber, so it is highly breathable and its uses are very diverse. Although it looks like paper, we must not forget that it is plastic when it comes to recycling.

As we mentioned at the beginning of this section, desiccant bags are frequently used in containers for shipping goods by sea.

Salt compounds and moisture can cause damage to the goods. For this reason, many containers come with special cables or rings for the placement of desiccants.

In this case, a hook or hooks, usually made of plastic or metal, are added to the bags to attach them to the walls of the container. If the container has no means of hanging the bag, many manufacturers incorporate a special adhesive to attach the bag directly to the inner side walls.

 

Other remarks

 

There is a chemical compound called dimethyl fumarate, DMF, which is also used as a desiccant.

Years ago the Finnish doctor Tapio Rantanen discovered that it can cause severe allergic reactions and large skin eczema, even in very small proportions, after the marketing of this product in sofas by a Chinese company, with the aim of preventing the furniture from deteriorating with humidity, resulting in several cases of affected people in several countries around the world, including Spain.

For this reason it is very important to make sure that the desiccant that we are going to use is free of this substance and that it has passed the pertinent controls that indicate it.

It is also common to find in the desiccant packages cards indicating the moisture content of the salts, thus warning if it is necessary to replace the package in case they no longer absorb water vapor.

Indicator cards

These cards work by changing color, in such a way that when their blue color disappears and turns to a light pink, as in the case of silica gel, it means that the desiccant salts have already exhausted their absorption capacity.

 

In conclusion, you will have to choose the type of desiccant that you believe convenient and in the right measure depending on the volume of the load and how it is packed. It is always advisable to use it, since humidity is present everywhere and in certain regions and countries more than in others, but above all it is an indispensable requirement for sea and river transport, combining it with other types of materials for adequate protection.
