Which material is typically used for the lining in a container?

Plywood or similar materials are commonly used for the lining in a container due to their durability and strength. These materials provide a stable surface that can withstand the rigors of transporting various cargo types. They offer protection against impacts and help maintain the structural integrity of the container. Additionally, plywood can be treated to resist moisture and other environmental factors, which is essential for preventing damage to the cargo inside.

While plastic sheeting can be used for moisture barriers, it does not provide the same level of support and structural strength as plywood. Steel reinforcement is typically used for the frame or structure of a container rather than its lining. Foam insulation, while beneficial for temperature control, is not usually employed as a main lining material in cargo containers. Therefore, plywood or similar materials are the most suitable choice for providing effective cargo support and protection within containers.
