Canadian startup Freshr patents a compostable antimicrobial microgel for meat packaging

What Happened

Freshr Sustainable Technologies patented a naturally-derived, non-migrating antimicrobial microgel — the core of its FreshrPack™ line — designed to extend shelf life for fresh fish, meat, and poultry while remaining fully compostable, tackling food waste and plastic waste together.

Why It Matters

A non-migrating antimicrobial — one that works at the packaging surface instead of leaching into the food — sidesteps the regulatory and consumer-trust questions that migrating preservatives raise, while still extending shelf life for fresh proteins.

Kills bacteria at the surface, breaks down in a compost bin — most solutions can't claim both.

FET's Takeaway

Fully compostable is the harder engineering constraint here — most antimicrobial packaging solutions trade away compostability for performance, so holding both at once is the real claim to verify at scale.
