The European Food Safety Authority (EFSA) has determined the food safety of plastic polyethylene terephthalate (PET) when produced by a recycling process called Poly Recycling for use in food contact materials.
Poly Recycling involves the input of washed and dried PET flakes originating from collected post-consumer PET containers, including no more than 5 percent PET from non-food consumer applications. The flakes are heated in a reactor before being extruded.
