Metallyte™ MLB20

Oriented Polypropylene Film

Product Description

Metallyte  MLB20 is an enhanced-barrier clear metallized film designed for heat sealable applications. Due to its low temperature sealing face and very wide sealing range, MLB offers an excellent performance on HFFS machines and ensures excellent bond strength when laminated to other substrates. The improved barrier properties make it an excellent choice for packaging of sensitive products, combining great product protection and yield advantage.
