Which type of container is NOT mentioned as a type of end-opening container?

End-opening containers are specifically designed with openings at the ends to facilitate loading and unloading cargo, particularly in bulk or oversized applications. The types of containers typically categorized as end-opening include metallic and composite materials known for their structural integrity and suitability for various cargo types.

Steel, aluminum, and fiberglass reinforced plywood are all widely recognized materials used in constructing end-opening containers. Steel and aluminum are favored for their strength and durability, while fiberglass reinforced plywood is valued for being lightweight yet strong, making it applicable in intermodal transportation. These materials can be effectively designed to meet the end-opening requirements, ensuring easy access for cargo handling.

Plastic, on the other hand, is not generally associated with end-opening container designs in conventional shipping practices. While plastic may be used in smaller containers or for specific packaging solutions, it lacks the structural capabilities and durability that heavier or bulk cargo typically requires in the context of intermodal shipping. Thus, it does not fit into the standard definitions of end-opening containers broadly utilized in the shipping and transport industry.
