发明名称 Sealant layer for container lid
摘要 A sealed composite container for products is provided having a paperboard body ply with a liner ply adhered on the inner surface thereof. One end of the container is rolled outwardly to form a rim and exposing the inner surface of the liner ply. A lid is heat sealed to the rim of the container. The dual-layer sealant composition layer of the lid comprises a base layer, such as high density polyethylene, and an adjacent frangible layer, such as ethylene-methyl acrylate copolymer, the frangible layer being operatively positioned for heat sealing to the rim of the container.
