Description
Material Notes:
Data provided by DuPont Packaging Polymers.A transparent polyester packaging film, solvent coated on one side with a PVDC copolymer. The coating is heat sealable, and is an excellent moisture and oxygen barrier. Available in 50 and 75 gauges, with the coated side normally wound toward the core. Designed to be reverse printed on the coated side, then combined with a sealant layer such as polyethylene or Surlyn® ionomer resin – locking in the PVDC coating.
