Metallyte™ UBWES - Oriented Polypropylene Film

FLEXIBLE PACKAGING PRODUCT DATA SHEET

Product Description

MetallyteTM UBWES is a multi-layer, cavitated, white OPP film with an enhanced sealant to allow sealing through contamination. This film has an exceptional barrier to gases, flavors, and moisture. It is metallized on one side with a proprietary sealant layer on the other. UBWES is lap sealable to other coextruded OPP films.
