Title (EN) LAMINATED FILM AND FOOD PACKAGING BAG
(FR) FILM STRATIFIÉ, ET SAC D’EMBALLAGE ALIMENTAIRE
(JA) 積層フィルム及び食品包装袋
Abstract:
(EN) This laminated film has at least a surface layer (A), an intermediate layer (B), and a seal layer (C), wherein one outer layer of the laminated film is the surface layer (A) and the other outer layer of the laminated film is the seal layer (C). In this laminated film, the surface layer (A) and the seal layer (C) each contains a propylene-based resin; and the intermediate layer(B) contains a plant-derived biomass polyethylene(b1), a petroleum-derived polyethylene(b2) and a propylene-based block copolymer resin. This laminated film enables suitable sealing strength or impact resistance to be achieved while using a resin plant-derived component.
(FR) L’invention concerne un film stratifié qui possède au moins une couche de surface (A), une couche intermédiaire (B) et une couche de scellement (C), une couche superficielle étant constituée de la couche de surface (A), et l’autre couche superficielle de la couche de scellement (C). Ce film stratifié comprend une résine à base de propylène dans la couche de surface (A) et la couche de scellement (C), et la couche intermédiaire (B) comprend un polyéthylène de biomasse dérivé de plantes (b1), un polyéthylène dérivé de combustibles fossiles (b2), et une résine de copolymère séquencé à base de propylène. Ainsi, tout en s’adaptant à un composant dérivé de plantes ou de résine, ce film stratifié permet de développer une solidité de scellement et une résistance aux chocs satisfaisantes.
(JA) 少なくとも表面層(A)、中間層(B)及びシール層(C)を有し、一方の表層が表面層(A)、他方の表層がシール層(C)からなる積層フィルムである。そして、当該積層フィルムは、表面層(A)及びシール層(C)にプロピレン系樹脂を含有し、中間層(B)が植物由来のバイオマスポリエチレン(b1)化石燃料由来のポリエチレン(b2)とプロピレン系ブロック共重合樹脂を含有する積層フィルムにより、樹脂植物由来成分を適用しつつも、好適なシール強度や耐衝撃性を実現できる。
