Polyethylene terephthalate (PET) is widely used in the food and beverage packaging sector due to its chemical mechanical properties. Although PET a fossil-based polymer, recyclability significantly contributes reducing environmental impacts caused by excessive plastic consumption. However, growing demand for post-consumer recycled (PET-PCR) has raised concerns about efficiency of decontamination processes involved recycling this material. This review initially addresses synthesis processes, highlighting injection stretch blow molding as predominant technique production. It then discusses reverse logistics strategy promote sustainability through recovery packaging, such bottles. examines methods PET-PCR production, safety requirements including positive lists permitted substances, contaminant migration limits, non-intentionally added substances (NIASs), updated criteria National Health Surveillance Agency (ANVISA) food-grade resins. Finally, explores future prospects using sector, assessing potential technological advancements enhance safety.
