DuPont Teijin Films Mylar® LBT-2 Polyester Packaging Film, 48 Gauge
Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film
Material Notes:	Data provided by DuPont Packaging Polymers. Mylar® LBT-2 is an uncoated, transparent, exceptionally strong film used as a substrate for laminating and extrusion coating and as a component of packaging structures requiring great strength, high temperature performance and good machinability. It is corona treated on two sides for improved bonding of inks and adhesives. Mylar® LBT-2 can be readily printed with appropriately formulated commercial inks. Consideration should be given in film handling and final package design to the increased susceptibility of the two contacting corona treated surfaces to blocking, particularly in the presence of moisture.
