Abstract: The present invention relates to thermoformed plastic articles such as frozen food trays which exhibit unexpectedly high impact strength at low temperatures. The articles are obtained from polyester blends containing 88 to 99 weight percent of a poly(ethylene terephthalate) resin and 1 to 12 weight percent of a poly(1,4-cyclohexylenedimethylene terephthalate) resin which contains at least 30 mole percent of 1,4-cyclohexanedimethanol.
Abstract translation: 本发明涉及热成型塑料制品，例如在低温下具有出人意料的高冲击强度的冷冻食品托盘。 该制品由含有88-99％（重量）聚（对苯二甲酸乙二醇酯）树脂和1至12％重量的聚（1,4-环己烯二甲基对苯二甲酸乙二醇酯）树脂的聚酯共混物获得，该树脂含有至少30摩尔％的1,4 -cyclohexanedimethanol。

Abstract: A modified atmospheric package for containing foodstuffs without spoilage is made from a tray of a foamed thermoformable polyester and a film lid of a non-thermoformed polymer. The foamed polyester is made from repeat units from an acid component of at least 65 mole percent terephthalic acid or naphthalenedicarboxylic acid and repeat units from a glycol component of at least 65 mole percent ethylene glycol or 1,4-cyclohexanedimethanol.
