PAKDRY7500

PAKDRY7500 is a 7.5 mil thick (minimum) high moisture and gas (oxygen, carbon dioxide et al) barrier film with a dual layer of both 48 gauge polyester and 60 gauge biaxially oriented nylon providing very high tensile strength and resistance to puncture, making this product suitable for vacuum packaging applications and for very large bags including cargo container liners. As an FDA approved substrate for food contact the 6.0 mil MINIMUM metallocene P.E. sealant layer has made this the product of choice for bulk food, fine pharmaceutical powders and medical device engineering specifications.

NOTE: Our PAKDRY7500 structure is 7.5 mils minimum with an FDA approved sealant layer.
