PAKVF3.5D

This lamination of film foil and polyethylene has a wide range of uses where a high barrier film is needed with a low WVTR. It is ideal for packaging of hygroscopic items and products susceptible to corrosion, and in food or medical device packaging, where very low oxygen levels are required.

NOTE: PAKVF3.5D is 3.5 mils thick and offers the appropriate barrier for food products. In some unique applications where an even stronger barrier is needed, we offer 5 mil thick PAKVF4C structure is 5.0 mils minimum also with an FDA approved sealant layer.
