Metallyte™ 28UBWES
Oriented Polypropylene Film
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.
UBWES is used as the inner web for adhesive and extrusion laminations, where superior moisture and oxygen barriers are required. UBWES provides an excellent light barrier and is designed to provide strong, leak-free seals for flat pouches and has been designed specifically to replace foil and a sealant web in those applications.
