PET film (Polyester Film) is used successfully in a wide range of applications, due to its excellent combination of optical, physical, mechanical, thermal, and chemical properties, as well as its unique versatility.
Characteristics:
1). Optically brilliant, clear appearance
2). Unequaled mechanical strength and toughness
3). Excellent dielectric properties
4). Good flatness and coefficient of friction (COF)
5). Tear-resistant and puncture-resistant characteristics
6). Excellent dimensional stability over a wide range of temperatures
7). Very good resistance to most common solvents, moisture, oil, and grease
8). Excellent barrier against a wide range of gases.
9). Widely use for packaging, printing, laminating, metallizing, decroation, electrical insulation.
