以加有填料的结晶性聚对苯二甲酸乙二酯(CPET)为材料的托盘已被开发用以与热固性聚酯食物托盘竞争。这种被制造者称之为结构设计独特的CPET托盘是由特殊组成的填料和高分子量热塑性PET组成的。这种透明坚韧的托盘由于具有良好的阻隔水蒸汽性,良好的阻氧性和耐化学腐蚀性,而在食品、医药及工业方面使用。它也适用于气体或γ射线消毒的场合。这种托盘在室温下的刚性是CPET的两
Trays made of filler-filled crystalline polyethylene terephthalate (CPET) have been developed to compete with thermosetting polyester food trays. This type of CPET pallet, which the manufacturer calls a structurally unique design, consists of a special composition of filler and high molecular weight thermoplastic PET. This transparent, tough pallet is used in food, pharmaceutical and industrial applications due to its good vapor barrier properties, good oxygen barrier and chemical resistance. It is also suitable for gas or gamma ray sterilization applications. The rigidity of this tray at room temperature is two for CPET
