The EFSA Panel on Food Contact Materials (FCM) assessed the safety of the recycling process NGR LSP (EU register number RECYC328). The input is hot washed and dried poly(ethylene terephthalate) (PET) flakes mainly originating from collected post-consumer PET containers, with no more than 5% PET from non-food consumer applications. The flakes are dried (step 2), melted in an extruder (step 3) and decontaminated during a melt-state polycondensation step under high temperature and vacuum (step 4). In step 5, the material is granulated. Having examined the challenge test provided, the Panel concluded that the melt-state polycondensation (step 4) is critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of step 4 are the pressure, the temperature, the residence time and the characteristics of the reactor. It was demonstrated that this recycling process ensures that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.0481 or 0.0962 μg/kg food, depending on the molar mass of a contaminant substance. Therefore, the Panel concluded that the recycled PET obtained from this process is not of safety concern, when used at up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs, including drinking water, for long-term storage at room temperature or below, with or without hot-fill. Articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such uses are not covered by this evaluation.
欧洲食品安全局食品接触材料（FCM）小组评估了回收工艺NGR LSP（欧盟注册号RECYC328）的安全性。其输入物是经过热洗和干燥的聚对苯二甲酸乙二酯（PET）薄片，主要源自收集的消费后PET容器，非食品消费用途的PET含量不超过5%。这些薄片经过干燥（步骤2）、在挤出机中熔化（步骤3），并在高温和真空下的熔融态缩聚步骤中进行去污处理（步骤4）。在步骤5中，材料被造粒。在审查了所提供的挑战测试后，小组得出结论，熔融态缩聚（步骤4）对于确定该工艺的去污效率至关重要。控制步骤4性能的操作参数是压力、温度、停留时间和反应器的特性。结果表明，这种回收工艺可确保潜在未知污染物向食品中的迁移水平低于根据污染物物质摩尔质量保守模拟的0.0481或0.0962μg/kg食品的迁移量。因此，小组得出结论，当以高达100%的比例用于制造与所有类型食品（包括饮用水）接触的材料和制品时，该工艺获得的再生PET在室温或更低温度下长期储存（无论是否热灌装）不存在安全问题。由这种再生PET制成的制品不适用于微波炉和传统烤箱，本评估不涵盖此类用途。
