发明名称 Composite container and method of heat sealing composite containers
摘要 A sealed composite container is provided having a tubular body member and a liner ply adhered to the inner surface of the tubular body member. An end of the body member and liner ply is rolled outwardly to form a rim and a lid is heat sealed to the rim. A tacky composition is in contact with the rim and the lid and is positioned therebetween. The tacky composition has sufficient tackiness to temporarily hold the lid in place overlying the rim. At least one of the lid and liner ply comprises a seal layer comprising a heat sealable composition. The tacky composition and the heat sealable composition form a heat seal between the lid and the liner ply, the tacky composition being chemically compatible with the heat sealable composition such that a fusion seal is formed therebetween.
