The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the recycling process Jász-Plasztik (EU register number RECYC0157). The input are hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers and containing no more than 5% PET from non-food applications. They are heated in a batch reactor under vacuum and then heated in a continuous reactor under vacuum before being extruded into pellets. Having examined the results of the challenge test provided, the Panel concluded that the decontamination in the batch reactors (step 2) and in the continuous reactor (step 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, pressure and residence time. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 μg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process when used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill, is not considered of safety concern. Trays made of this recycled PET are not intended to be used in microwave and conventional ovens and such use is not covered by this evaluation.
欧洲食品安全局食品接触材料、酶和加工助剂小组（CEP小组）评估了Jász-Plasztik回收工艺（欧盟登记号RECYC0157）的安全性。其输入物是经过热碱洗和干燥的聚对苯二甲酸乙二酯（PET）薄片，这些薄片来自收集的消费后PET容器，且非食品应用的PET含量不超过5%。它们先在间歇式反应器中真空加热，然后在连续式反应器中真空加热，之后再挤出制成颗粒。在审查了所提供的挑战试验结果后，小组得出结论，间歇式反应器（步骤2）和连续式反应器（步骤3）中的去污是决定该工艺去污效率的关键步骤。控制这些关键步骤性能的操作参数是温度、压力和停留时间。结果表明，这种回收工艺能够确保潜在未知污染物向食品中的迁移水平低于保守模拟的0.1μg/kg食品的迁移量。因此，小组得出结论，该工艺获得的再生PET在用于制造与所有类型食品接触的材料和制品以在室温下长期储存（有无热灌装）时，即使100%使用也不存在安全问题。用这种再生PET制成的托盘不打算用于微波炉和传统烤箱，本评估不涵盖此类使用情况。
