Standard PA/PE film has OTR 20–40 cm³/m²/day. Adding EVOH reduces this to ≤ 3 cm³/m²/day — a 10–15× improvement that directly translates to longer shelf life and better color retention for fresh red meat.
EVOH barrier decreases slightly at high relative humidity (>85% RH). Our film design positions the EVOH layer in the center, protected by outer PA and PE layers that act as moisture barriers.
Yes. We offer high barrier EVOH lidding films that pair with our EVOH bottom web for complete high-barrier pack solutions. Please specify peelable or non-peelable seal when requesting samples.
