    • The present invention relates to a process for thermoforming a foamed polyester sheet of low crystallinity to produce a heat-resistant molded foam article (13). The process comprises the steps of heating a foamed polyester sheet (10) to a preforming temperature by contact with at least one heating plate and molding the heated foamed polyester sheet onto a non-heated mold (30). The present invention further relates to a process for manufacturing a package by thermoforming a foamed polyester sheet of low crystallinity to produce a heat-resistant molded foam container, loading a product (51) into said container and sealing or welding a film of thermoplastic material (61) onto said container to close it. The heat-resistant molded foam articles and the packages thus obtained are excellent in heat resistance and are not thermally distorted even when heated in a microwave or conventional oven. They are particularly useful for the packaging of food products for dual ovenable applications.
    • 本发明涉及一种用于热成型低结晶度的发泡聚酯片材以制备耐热成型泡沫制品(13)的方法。 该方法包括以下步骤:通过与至少一个加热板接触将发泡聚酯片材(10)加热到预成型温度,并将加热的发泡聚酯片材模制到未加热的模具(30)上。 本发明还涉及一种通过热成形低结晶度的发泡聚酯薄片来制造包装的方法,以制造耐热成型泡沫容器,将产品(51)装入所述容器并密封或焊接热塑性材料薄膜( 61)到所述容器上以将其关闭。 由此获得的耐热成型泡沫制品和包装件具有优异的耐热性,并且即使在微波炉或常规烤箱中加热也不会发生热变形。 它们特别适用于双重可烘烤应用的食品包装。
