| abstract | 【Task】 INDUSTRIAL APPLICABILITY The present invention can be used as a sealant for packaging bags without powder because it has excellent heat-sealing properties, low-temperature impact resistance, and blocking resistance, and can also be suitably used for retort pouch applications due to its excellent surface resistance. Furthermore, when the packaging bag filled with retort food is heated in a microwave oven or the like, the sealing force is reduced and the packaging bag is vaporized, so that the packaging bag can be prevented from breaking and the contents from being scattered or leaking out. Provided are a polypropylene-based composite film and a packaging material using the same. SOLUTION: It is a polypropylene-based composite film in which a seal layer (B) is laminated on at least one side of the base material layer (A), and the base material layer (A) is a propylene / ethylene block copolymer (a1) of 75 to 90. A resin composition containing 10 to 25% by weight of linear low-density polyethylene (a2), and the seal layer (B) contains 30 to 40% by weight of propylene / ethylene block copolymer (b1) and propylene. 30 to 50% by weight of ethylene block copolymer (b2), 15 to 25% by weight of homopolypropylene (b3), 3 to 10% by weight of linear low-density polyethylene (b4), crystal nucleating agent (b5). A polypropine-based composite film containing 50 to 5000 ppm of a resin composition, wherein the above (b1), (b2), and (b5) are resin compositions satisfying specific conditions.
