Pfas-free high-barrier polymer coating for dairy packaging without aluminum foil
EraPolyCare provides a PFAS-free polymer coating that replaces aluminum foil in dairy packaging. The coating delivers high-barrier performance to help preserve freshness, supports recyclability-compatible packaging approaches, and maintains structural integrity at processing and storage temperatures (150–180°F). It is designed to work with commercial coating and film processes and targets improved oxygen and water vapor barrier performance for extended shelf life.
Overview
EraPolyCare presents a PFAS-free polymer coating designed to replace aluminum foil in dairy packaging. The coating provides high-barrier properties essential for preserving product freshness while supporting sustainability objectives. It is intended to be compatible with existing recycling streams, contributing to recyclable/reusable/compostable packaging targets. The coating maintains structural integrity at elevated temperatures (150–180°F), supporting product quality and safety during processing and storage.
Technical specifications
Key features:
- PFAS-free coating eliminates the need for aluminum foil, reducing environmental impact
- Maintains required dead fold and stiffness at high temperatures to preserve structural integrity
- Targets oxygen transmission rate (OTR) and high water vapor transmission rate (WVTR) performance for extended shelf life
- Compatible with commercial processes such as cast film, extrusion, and roll coating
- Designed to support food safety regulatory compliance and existing recycling processes
Technology readiness level
The technology is currently at TRL 5, with ongoing substrate optimization and process compatibility testing. The goal is to reach TRL 8 to enable mass production tailored to specific packaging needs. The coating has been validated in thermoforming processes and is undergoing further evaluations for barrier properties and regulatory compliance.
