Aluminum-plastic film and substrate for aluminum-plastic film

Abstract

An aluminum-plastic film and a substrate for an aluminum-plastic film are provided. The aluminum-plastic film includes a polyester layer, a composite resin layer, a polyamide layer, and an aluminum layer. The composite resin layer is disposed between the polyester layer and the polyamide layer. The aluminum layer is disposed on the polyamide layer. The polyester layer, the composite resin layer, and the polyamide layer are integrally formed by co-extrusion. The composite resin layer includes a terpolymer and a polyolefin resin. Based on a total weight of the composite resin layer being 100 wt %, an amount of the terpolymer is higher than 45 wt %. The terpolymer contains structural units of ethylene butyl acrylate.
