MYLAR® LBT

Product Description

Mylar® LBT is an uncoated, transparent polyeser film that has been corona treated on one side to provide superior wetting and adhesion of inks, primers and adhesives. Mylar® LBT is commercially available in nominal 48, 75 and 92 gauges. Other gauges may be available upon request. The standard wind-up presents the corona-treated side facing the roll core.

General Product Info

In addition to the enhanced wettability offered to inks, primers, adhesives and coatings, Mylar® LBT offers all of the properties attributed to Mylar® LB, including high levels of strength, temperature resistance and flavor and odor barriers. Its sparkling clarity and insensitivity to humidity make Mylar® LBT a preferred print carrier.

Typical Applications

Mylar® LBT typically is used as the reverse printed outer ply of a lamination with inner plies providing additional oxygen barrier if needed, as well as heat sealability. The availability of the two-side corona-treated Mylar® LBT2 permits use where the ply will be buried inside a lamination with bonding to both surfaces or where the exposed outer surface will subsequently receive surface printing, code dating or some for of package lot identification.
