The coextruded, highly transparent Multifol GVA-PT bottom web is made of polyamide, polyester, and polyethylene layers as well as an EVOH high barrier. It has a particularly high oxygen barrier and can be used for MAP packaging as well as vacuum packaging. After being used on thermoforming systems, it is particularly durable and puncture resistant. Thanks to an improved sealing layer, it can be securely sealed at low temperatures and despite the sealing area being contaminated by the product. The sealed seams have a very good hot tack and remain stable while still hot.
