用包装袋。[Claims for Utility Model Registration] (1) (A) An easily peelable adhesive layer 2, a stretched polyester layer 3, and an unstretched polypropylene film layer 4 are laminated in this order, and the laminate is penetrated. (b) a covering layer B in which a stretched polyester film layer 6, an aluminum foil 7, and an unstretched polypropylene film layer 8 are laminated in this order; C) Covering the base layer A with a polypropylene layer 9 melt-pressed so that the adhesive layer 2 of the base layer A and the unstretched polypropylene film layer 8 of the coating layer B are adjacent to each other. Layer B is adhered, and a melt-extruded polypropylene layer 5 is further bonded to the surface of the unstretched polypropylene film layer 4 of the base layer A.
A laminate C is constructed by directly bonding this polypropylene layer 5 and the polypropylene layer 9 together in the ventilation hole 10; (e) The other surface 1b constituting the packaging bag is made of the same constituent layers as the above-mentioned laminate C, or is made of the same constituent layers as the above-mentioned laminate C. The polypropylene layer 5 of these laminates is not provided with the ventilation hole 10 and is constructed into a bag shape using the polypropylene layer 5 as the inner surface of the packaging bag, or the layer is a constituent layer in which the polypropylene layer 5 is omitted from the laminate C. A packaging bag for retort food, characterized in that it has no ventilation holes 10 and is constructed in a bag shape using the non-stretched polypropylene film layer 4 of these constituent layers as the inner surface of the packaging bag. (2) The retort food packaging bag according to claim (1), wherein the stretched polyester film layer 3 is a laminate of a stretched polyester film and a stretched nylon film.
