PP food containers preserve oxygen barrier after retort
from Packaging Digest
Food manufacturers seeking high-barrier packaging materials at a lower cost without performance trade-offs now have another cost-effective option to consider. New REVOH technology from Winpak Portion Packaging Inc. is engineered to enhance the post-retort oxygen barrier of thermoformed containers by reducing oxygen ingress 30 to 35 percent during the critical time when the packaging's EVOH oxygen barrier layer is most vulnerable to penetration - immediately after retort.
