LeapFreshSeal™ — Plastic Food Trays & Thermoformed Containers
rPET Available PP 121°C MAP Compatible
FreshSeal™ — Engineered for the Full Cold Chain
Thermoformed trays for production → blast freezing → transport → retail display → consumer microwave. PET: 88–92% clarity, ambient/chilled. PP: microwaveable to 121°C. RPET: 30–100% GRS-certified PCR. All FDA 21 CFR + EU 10/2011. Critical spec: flange flatness ±0.4mm — beyond that, heat-seal fails and MAP shelf life is compromised. Verified by CMM and vacuum decay every batch.
