摘要： Provided is a coextruded film including an adhesive layer, which is formed from a blend of a maleic anhydride modified polyolefin resin and a polyolefin resin, between a barrier layer that is formed from an ethylene vinyl alcohol copolymer, and a sealant layer that is formed from a polyolefin resin. When this adhesive layer is applied, it is possible to provide a coextruded film which has a sufficient barrier property due to the barrier layer formed from the ethylene vinyl alcohol copolymer, and in which surface gloss is satisfactory, and irregularities are suppressed, and thus the exterior appearance thereof is excellent.
