Packaging for sea transport: how to choose the right one

Packaging is an essential part of transporting goods by sea efficiently and safely.
Nowadays, the possibilities for shipping goods all over the world are endless: air, sea and land transport. In this sense, each transport route has its specific characteristics and, depending on the one we choose, we will have to adapt the type of packaging to this one to guarantee a safe shipment.

In this case, we will deal with the most important points at the time of choosing a packaging for maritime transport.

An aspect to emphasize is that the great majority of insurances for the marine transport cover great part of the risks associated to this type of transport, but they do not cover the losses caused by a bad stowage, among them a deficient packing. This is one more reason to take special care with the packaging we choose when transporting our products by sea.


Special features of the maritime environment

These are some of the most important features of maritime transport:

-Environment of humidity and salinity: This differentiating point of the sea means that we have to pay special attention to the packaging for maritime transport as the goods will be exposed to rust and corrosion, much more than in any other means of transport.

-Extreme temperatures: In maritime containers, which are the elements most used for transport by sea, temperatures can reach maximum values, both cold and heat.

-Contamination: Many products cannot be in contact with the environment or with other goods, since their qualities, such as food, would be altered.

-Sudden movements of cargo: In sea transport, containers are transported and placed by cranes, which can sometimes cause sudden movements of goods.

Elements used in maritime transport

Among the most important resources to ensure proper maritime packaging are the following:

-Maritime containers: This is the most important element of packaging for maritime transport. They are manufactured under the ISO (International Organization for Standardization) standard. That is why they are also called ISO containers. 

Thanks to their robustness, they are ideal for preventing possible damage due to sudden movements of goods during loading and unloading operations. 

In addition, among the different types of containers, we can choose a refrigerated maritime container, with which we can avoid extreme temperatures.

-Fixing system: This refers to any element used to immobilize the cargo inside the container and thus avoid damage caused by sudden movements in loading and unloading. Among the most important are: mooring belts, air bags, steel cables, wooden supports, etc.


-VCI aluminium and desiccant salts: These are two barrier and anti-humidity materials, which protect the load especially against corrosion, mould and various damage caused by constant excess humidity.

-Isothermal insulators: This type of protection protects products and goods from temperature changes without the need for special containers.

-Containers for liquids and bulks: These are antiseptic and safe containers for the transport of liquids and bulks and ensure their insulation and prevent product contact with other substances. These include big bags, liners, flexitanks etc.

In conclusion, the sea has some peculiarities of its own that make it absolutely necessary to be very meticulous when choosing the best packaging for maritime transport to prevent damage or loss and ensure proper transport of cargo by sea.

NIMF-15 regulation for heat treatment of wood in foreign trade
Heat treatment of wood
The heat treatment of wood is a critical process used to eliminate pests and diseases, as well as to comply with international regulations governing the trade of wood abroad. The NIMF-15 standard, in particular, establishes the requirements for the heat treatment of wood used in packaging used in international trade.

In this sense, heat sealing for wood packaging is an effective technique to ensure that these regulations are met. By using this technique, the risk of pests and diseases entering the destination country is avoided, which could lead to serious economic and environmental consequences.
It is important to mention that heat sealing for wood packaging is a process that must be carried out by trained professionals and with the appropriate machinery to guarantee its correct application.
