摘要： A heat sealable polypropylene resin laminate film having good toughness and heat sealing strength and energy sufficient for packaging heavy goods, mainly fruits and vegetables, and a package made of such film, is a laminate film having three or more layers, a substrate layer made of a crystalline polypropylene resin, a heat sealable layer having a melting point of not more than 150° C., and an intermediate layer. The product of the tensile modulus of elasticity (GPa) in both orthogonal directions of the film is 3.1-6.0 (GPa)2, and the heat sealing energy is not less than 11N·cm/15 mm when the film is sealed, such that the heat sealing strength of the film is not less than 8N/15 mm.
