Zusammenfassung: | To provide a heat-shrinkable gas barrier film which can extend a freshness holding period of a food product, is excellent in shrinkage finishing property in a gas substitution packaging machine, can suppress deformation of the container, and is difficult to impair appearance of a package, in a form of overlapping and heat-shrinkable packaging a container storing a food product with the gas substitution packaging machine.SOLUTION: A heat-shrinkable gas barrier film is a heated laminated oriented film including at least a heat seal layer (A), an adhesive layer (B), a gas barrier layer (C), an adhesive layer (B) and a heat seal layer (A) in this order. The heat seal layer (A) is a layer containing an ethylene-based resin as a main component, the adhesive layer (B) is a layer containing an olefinic adhesive resin as a main component, and the gas barrier layer (C) is a layer containing a saponified ethylene-vinyl acetate copolymer as a main component.SELECTED DRAWING: None
【課題】食品を入れた容器をガス置換包装機にてオーバーラップ熱収縮包装する形態において、食品等の鮮度保持期間を延長することが可能であり、且つ、ガス置換包装機において収縮仕上がり性に優れ、容器の変形を抑制でき、包装物の美観性を損ないにくい熱収縮性ガスバリアフィルムを提供する。【解決手段】ヒートシール層(A)、接着層(B)、ガスバリア層(C)、接着層(B)及びヒートシール層(A)を少なくともこの順に含む加熱積層延伸フィルムであって、前記ヒートシール層(A)はエチレン系樹脂を主成分とする層であり、前記接着層(B)はオレフィン系接着性樹脂を主成分とする層であり、前記ガスバリア層(C)はエチレン−酢酸ビニル共重合体ケン化物を主成分とする層である熱収縮性ガスバリアフィルム。【選択図】なし |
