Image of MYLAR® LB clear polyester film

MYLAR® LB is an uncoated, transparent polyester film designed for use as a component of a lamination structure. It is available with corona treatment on one or both sides. These products are known as MYLAR® LBT and MYLAR® LBT2 respectively.

MYLAR® LB polyester film frequently is selected as a component of a laminated structure because of its ability to contribute great strength, high temperature resistance, and flavor/odor barrier. Its sparkling clarity and relative insensitivity to heat and humidity make it an ideal print carrier and outer ply of many laminated food packaging structures. Retention of properties over a temperature range from -100°F to 300°F permits uses requiring freezer storage temperatures followed by heating for warming, cooking or ovenable applications. The chemical resistance and barrier to acids, weak bases, greases and oils, detergents and other active ingredients make MYLAR® LB useful in containing many "hard-to-hold" food or non-food products. MYLAR® LB is not degraded by standard sterilization procedures involving steam retorts, gamma or cobalt radiation, ethylene oxide gas exposure, or hydrogen peroxide immersion.
