This lamination of film foil and polyethylene has a wide range of uses where a high barrier film is needed with a low WVTR (water vapor transmission rate.) 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.
PAKVF4D is identical to PAKVF4 in construction; the foil is laminated "face down" to expose the dull side which is preferred in some applications.
