Abstract
Provided is a molded body in which at least one surface layer made of a copolyester polymer is laminated on one surface or both surfaces of a base layer made of aliphatic polycarbonate. When coextruding aliphatic polycarbonate and copolyester polymer, two layers adhere well to each other and are hardly delaminated from each other even without an adhesive and a tie layer, oxygen barrier property and low-temperature heat seal property can be provided as compared with a case where the copolyester polymer alone is used, the cost can be reduced because a separate adhesive or a tie layer is not required, and the manufacturing cost can be significantly reduced because the constitution of layers is simplified.
