PURPOSE:To provide the laminated wrapping material in which low-temperature heat sealing property, heat sealing strength, resistance to pinhole, gas barrier property, maintenance of flavor, impact resistance and bag-breaking strength or the like are excellent and constitution of a layer is simple and forming is easy and especially suitable to food wrapping for preventing reduction of a flavor component. CONSTITUTION:Laminated wrapping material is constituted by bonding a biaxially stretched polypropylene film layer to the metal vapor deposition face of a polyester composition layer in which metal is vapor-deposited through a layer consisting of an ethylene-unsaturated carboxylic acid copolymer or its ionomer. The polyester composition consists of 70-95 pts.wt. copolymerized polyethylene terephthalate containing 3-15mol% copolymerized component and 5-30 pts.wt. ionomer of the ethylene-unsaturated carboxylic acid copolymer. |
