PURPOSE:To provide an easily strippable film retaining the flavor of content such food in a package filled with food or the like, convenient to open and capable of being opened by stripping a heat-sealing part. CONSTITUTION:A first layer 1 composed of a heat-sealable polyester base plastic layer having adhesion with a material to be coated in a molten state and modified so as to have tensile breaking strength of 100-350kg/cm<2>, elongation at break of 30-100%, film interlaminar strength of 0.5-2.0kg/15mm and easy cohesive failure of thickness 15mum or less and a second layer 2 composed of a polyester base plastic layer bonded to the first layer 1 in a molten state and having no easy cohesive failure are laminated by coextrusion. |
