MULTILAYERED POLYESTER SHEET AND MOLDED ARTICLE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a multilayered polyester sheet excellent in heat resistance, impact resistance and container moldability and reducing the contamination of a mold at the time of molding, and a molded article thereof. SOLUTION: The multilayered polyester type sheet is constituted of two or more layers including at least one layer consisting of 99 wt.% or more of a polyester resin with an proper viscosity of 0.70 dL/g or more and 1 wt.% or less of a polyolefinic resin and at least a layer consisting of 92-99 wt.% of a polyester resin with an intrinsic viscosity of 0.70 dL/g or more and 1-8 wt.% of a polyolefinic resin of which the density measured based on JIS K-6760-1981 is 0.91 g/cm3 or less and/or 1-8 wt.% of a (copolymerized) polyolefinic resin containing an epoxy group. The molded article with a degree of crystallization of 10-40% is molded using this sheet.
