PAKVF4T
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: Our PAKVF4C structure is 5.0 mils minimum also with an FDA approved sealant layer.
