PAKVF4CNW

PAKVF4CNW is an ideal material for vacuum packaging products where protection against both moisture and oxygen are necessary. The nylon layer and the FDA approved metallocene poly inner layer (originally produced for PAKVF4C) is renowned for it's Strikethrough capabilities to seal through viscous liquids, lotions, and fine pharmaceutical powders while retaining seal integrity. The nylon layer makes this material excellent for vacuum sealing - even combined with a press to close zipper.
