MULTILAYER FILM, SHEET FOR PACKAGING, AND CONTAINER FOR FOOD PRODUCT

To provide a multilayer film which does not need to coat an adhesive to an inner layer of the multilayer film, and has an outer layer that is easily peeled from an ethylenic resin.SOLUTION: A multilayer film 10 includes an outer layer 11 which can be bonded to or peeled from a counter outer layer surface having an ethylenic resin, and an inner layer 16 which can be bonded to a counter inner layer surface having a polystyrene-based resin or a polypropylene-based resin, and has peeling strength of 3 N/15 mm or more when the counter inner layer surface and the inner layer 16 are thermally fused under conditions of a temperature of 150°C, a time of 2.0 seconds and a pressure of 0.2 MPa.SELECTED DRAWING: Figure 1 【課題】多層フィルムの内層に接着剤を塗布する必要が無く、且つ、エチレン系樹脂に対する剥離が容易な外層を有する多層フィルムを実現する。【解決手段】多層フィルム１０は、エチレン系樹脂を有する対外層面に対して接着及び剥離可能な外層１１と、ポリスチレン系樹脂、又は、ポリプロピレン系樹脂を有する対内層面に対して接着可能な内層１６とを備え、温度１５０℃、時間２．０秒、圧力０．２ＭＰａの条件で対内層面と内層１６とを熱融着させたときの剥離強度が、３Ｎ／１５ｍｍ以上である。【選択図】図１
