LeapPlastic Packaging — PET/PP/RPET Custom Manufacturer
Plastic Packaging — Precision Performance at Industrial Scale
Thermoformed PET and PP remain the dominant materials for fresh food, bakery, and ready-meal packaging for three technical reasons: crystal-clear product visibility (PET delivers 88–92% light transmission), consistent gas barrier performance for MAP shelf-life extension, and unit economics that beat paper by 10–30% at production scale. Three thermoforming lines produce over 300 million trays and containers annually. RPET with GRS certification available — price parity with virgin PET achieved in ~15 jurisdictions (2025).
