Abstract
A multilayer composite and an easily openable container produced by using the multilayer composite are provided. The multilayer composite comprises a surface layer of a polyolefin resin, an intermediate layer of a mixture of a polystyrenic resin with a thermoplastic elastomer or with a thermoplastic elastomer and a polyolefin resin, and a base layer of a polystyrenic resin, and the peeling strength between the intermediate layer and the base layer is larger than the peeling strength between the surface layer and the intermediate layer. The easily openable container produced by using the multilayer composite is capable of being sealed with a lid strongly while maintaining easy openability because the opening of the sealed container is performed utilizing the peeling between the surface layer and the intermediate layer.
