Patent Searching and Data


Title:
延伸積層フィルム及び袋
Document Type and Number:
Japanese Patent JP4848020
Kind Code:
B2
Abstract:
A stretched laminated film and bag is provided, in which a packaging operation in thermal shrinkage packaging is effectively performed without the occurrence of fusion and the like between margins when sealing via heat-sealing with a margin portion of an adjacent bag in a layered state, and without of bag whitening in a thermal shrinkage process thereafter. Specifically, a stretched laminated film has at least four layers of: a surface layer (A), an adhesive layer (A), a barrier layer, and a surface layer (B) sequentially laminated in order thereof, in which the melting temperature of the surface layer (A) is only increased no less than 65°C to no more than 150°C higher than the melting temperature of the surface layer (B), and the barrier layer is composed of a vinylidene chloride copolymer, and the melting temperature of the barrier layer is no less than 130°C to less than 160°C.
