DuPont Teijin Films Mylar® LBTW Polyester Film, 48 Gauge
Categories: Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film

Material Notes: Mylar® LBTW is an uncoated, transparent polyester film that has been corona treated on one side to provide superior wetting and adhesion of inks, primers, and adhesives. Mylar® LBTW is commercially available in nominal 48, 75 and 92 gauges. Mylar® LBTW is wound inverted with the corona-treated side facing the outside of the roll

General Product Info: In addition to the enhanced wettability offered to inks, primers, adhesives and coatings, Mylar® LBTW 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® LBTW a preferred print carrier.

Typical Applications: Mylar® LBTW 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.

Approvals: FDA Food Contact Status - All gauges of Mylar® LBTW comply with the Food and Drug Administration regulation 21 CFR 177.1630 -- Polyethylene phthalate polymers, sections (f), (g) and (h). These regulations describe films that can safely be used in contact with all types of foods including alcoholic beverages that do not exceed 50% alcohol by volume. The films listed above can be used to contain foods during oven cooking at temperatures up to and above 250°F. The films listed above may be used for packaging, transporting, or holding alcoholic beverages that do not exceed 50% alcohol by volume. UL Recognition - Product has been registered with Underwriters Laboratories. UL 94 VTM-2 - for 92 - 500 gauge (0.023 - 0.13mm) UL Recognition - for 92 - 500 gauge (0.023 - 0.13mm) - HWI=5, HAI=4, CTI=1
