Abstract

PURPOSE:To obtain a thermoformed partially crystallized polyester container, consisting of polyethylene terephthalate having a specific intrinsic viscosity, polymer with thermotropic liquid crystallinity and polyolefin and having excellent moldability, impact and heat resistance. CONSTITUTION:A container, obtained by thermoforming a polyester composition consisting of (A) 85-98.95wt.% polyethylene terephthalate having 0.65-1.2, preferably 0.75-1.1 intrinsic viscosity (20 deg.C), (B) 0.05-5wt.%, preferably 0.1-8wt.% polymer which is in a liquid crystal state at 260-320 deg.C that is a processing temperature of the component (A), preferably a polyester, consisting essentially of recurring units derived from hydroxybenzoic acid and having <=800 polymerization degree and (D) 1-10wt.%, preferably 2-6wt.% polyolefin, preferably polyethylene and/or polypropylene, having 15-80% crystallinity and most suitable especially as a container for cooked frozen food, etc.
