At least one layer of an aliphatic polyester resin, which is biodegradable and is also excellent in gas-barrier property and mechanical strength, is laminated with another thermoplastic resin layer to provide a satisfactory multilayer stretched product. The aliphatic co-polyester (A) has a crystallization temperature Tc1 due to crystallization in the course of heating, which is higher than the glass transition temperature Tg of another thermoplastic resin. |
