Description
Material Notes:
Data provided by DuPont Packaging Polymers.A transparent polyester packaging film, dispersion coated on one side with a PVDC copolymer. The coating is an excellent moisture and oxygen barrier. M45 is designed to be combined with a sealant layer, locking in the PVDC coating. M45 can be surface or reverse printed with appropriately formulated inks, and can be combined with other webs by adhesive or extrusion laminating. The coated surface is particularly well suited for water based inks and adhesives.
