Composite cans are cylindrical containers made from multiple layers of materials, designed to provide durability, strength, and versatility for packaging various products. These cans typically consist of a paperboard body and a metal or plastic base and lid, creating a robust structure that protects the contents inside. The paperboard layer serves as the primary material, providing rigidity, while the inner layers, often composed of foil or plastic, enhance the can's barrier properties, ensuring the preservation of the packaged goods by shielding them from moisture, light, and external elements.
