On September 29, 2015 the European Food Safety Authority (EFSA) published a scientific opinion on the post-consumer polyethylene terephthalate (PET) recycling process ‘San Miguel Industrias PET’. The process is based on the Starlinger IV+® technology and uses washed and dried PET flakes from post-consumer PET containers containing no more than 0.15% PET from non-food consumer applications. Based on conducted challenge tests and a reference contamination level of 3 mg/kg PET, EFSA’s Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) concluded that the processes can ensure that migration of potential unknown contaminants from the recycled PET into food does not exceed 0.1 µg/kg food. Therefore, CEF considers recycled PET obtained from the process safe for use in materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill. Trays made of this PET should not be used in microwave and conventional ovens.
