Materials

Metallized Polyester Film

Origin:       Made in China
Structure:   Metallized on one side, Corona treat on other side.
Feature:     A metallized bi-axially oriented polyester film exhibiting good metal adhesion and bright Al foil appearance. Consistently good handling properties, heat stability, slip, and high tensile strength for easy lamination. Featuring supior MVTR, OTR and light barrier properties. Providing superior oxygen and water vapor barrier. The polyester side is in compliance with the regulation FDS 21 CFR 177.1630(section f,.g,h),approved for direct food contact. The non-metallized side is FDA approved for indirect Food contact.
