A hermetic container liner is a specialized liner designed to create an airtight and watertight barrier within shipping containers. It is typically made of durable materials such as multi-layered films or laminated textiles. The purpose of a hermetic container liner is to provide an extra layer of protection for the cargo being transported, preventing moisture, dust, and contaminants from entering the container and potentially damaging the goods. It is particularly useful for industries dealing with sensitive or perishable products like food, chemicals, pharmaceuticals, or electronics, ensuring optimal conditions and preserving the quality of the cargo throughout its journey.
