Jan 08,2024

Cargo containers are vital in transporting import and export products by ship, train, or truck. And shipping container door seals are the essential element of these cargo containers. However, it is important to note that these ships, trains, or trucks travel through all types of weather and natural obstacles. Heavy winds, rain, or snow can be common natural obstacles. Therefore, shipping container door seals are mandatory to prevent water, air, or snow leakage. So, it is crucial to understand the fundamentals of container door gaskets.

This seal strip type is also famous as a container door gasket or shipping container weather stripping. Shipping container door seals are ideal for protecting and sealing out the container. It mainly works against water, snow, dust, or other contaminants. Therefore, shipping container door seals are the typical seal strip types used for weather stripping.

Continuous use of the shipping container door seals erodes the material gradually. As a result, it requires maintenance and replacement if necessary. Shipping container door seals are made of high-quality EPDM rubber. Here, EPDM stands for Ethylene Propylene Diene Monomer. It is a synthetic rubber primarily used for all outdoor applications. However, the specialty of this material is its outer membrane. It is an excellent air-tight and waterproof seal.
The most popular application of shipping container door seals is sealing cargo containers for ships, trains, or trucks. However, you could also use this seal strip in dry cargo containers of 20 feet and 40 feet high. Refrigerated containers of 20 feet and 40 feet tall also need this seal strip.
