Maritime transport: Practical guide to shipment of goods

By 360 Ecopackaging On 9 de May de 2024 0 Comments

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:

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.

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.

Aluminium Foil Barrier

By 360 Ecopackaging On 30 de November de 2022 0 Comments

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.

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.

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.

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.
