MULTILAYERED MOLDED PRODUCT, MULTILAYERED STRETCHED MOLDED PRODUCT COMPRISING IT AND MANUFACTURING METHOD OF MULTILAYERED MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a multilayered molded product which is formed into a multilayered stretched molded product characterized in that the transparency of a bottle even in a long-time continuous molding operation of a large number of bottles using the same heating and stretching mold because the content of a cyclic trimer in an outer layer or inner and outer layers is reduced and the flavor properties of the bottle are also enhanced, the multilayered stretched molded product comprising it and a manufacturing method of the multilayered molded product. SOLUTION: The multilayered molded product comprises at least a thermoplastic polyester layer (A) obtained from a molten polyester after melt polycondensation and a thermoplastic polyester layer (B) with a cyclic trimer content of 8,000 ppm or below, wherein a vapor deposition film formed by a plasma CVD method is laminated on a content contact surface.
