Topic:
Feasibility of recycled Polypropylene for Reusable Packaging Applications: This study evaluated the feasibility of post-industrial recycled polypropylene (PIR PP) for reusable food packaging, comparing it with virgin homopolymer (Homo PP) and copolymer (Co PP) grades. Injection-moulded containers underwent 20 simulated reuse cycles involving oven heating and commercial dishwashing, with assessments of thermal, mechanical, chemical, colour stability, microbial safety, and QR code traceability. PIR PP demonstrated comparable performance to virgin grades, with minor thermal changes in PIR PP and Co PP that did not affect dimensional stability. PIR PP met EN 1186 chemical migration limits, and microbial testing confirmed effective decontamination after each cycle. QR codes remained scannable across materials. The results support PIR PP as a viable, safe, and durable material for reusable food-contact applications, aligning with EU circular economy goals.
