<p>PROBLEM TO BE SOLVED: To provide a multilayer film that has a polypropylene resin layer and a polyester resin layer and that is capable of having efficient bond performance between layers without using an adhesive between the layers and capable of preventing occurrence of defects in secondary processing using the multilayer film.SOLUTION: There is provided a multilayer film where at least an A layer, a B layer, a C layer, and a D layer are laminated in this order. The A layer contains a polypropylene resin. The B layer consists of a resin (b) with a density of 0.88 to 0.92 g/cmmeasured according to JISK 7112 that comprises a copolymer of ethylene andα-olefin obtained by polymerization with a single site catalyst, where theα-olefin has 4 or more carbon atoms the content of the resin (b) is 65 mass% or more based on the total mass of the B layer. The C layer contains a polyethylene resin and the D layer contains a polyester resin.</p> |
