PURPOSE: To provide a composite film suitable for making pillow pack films in lamination with other films. CONSTITUTION: The extrusion composite film for laminate includes a first layer polyolefin resin, a second layer of a polyolefinic adhesive resin layer, a third layer of a polyamide layer, a fourth layer of an ethylene vinyl alcohol copolymer resin layer, a sixth layer of a polyolefinic adhesive resin layer and a seventh layer of a heat-sealing polyolefin layer, in which the film is allowed to laminate with other films in its first layer. The coextrusion composite film for laminate has a high heat-sealing strength and thus no likelihood of the occurrence of face-curl, so that it becomes suitable for pillow pack films in lamination with other films. |
