Manufactured from polyethylene terephthalate, polyester film is chemical and moisture resistance, with high tensile strength, dimensional stability, and working temperatures to 400°F. It can be coated with heat-sealable, friction or abrasive materials, metalized, punched, dyed and laminated. Heavier gauges of polyester can be stamped or vacuum formed, and lighter gauges can be wound into spiral tubes.
Polyester films come in a variety of opacities such as clear, very clear, slightly hazy, matte, translucent white, opaque white, and black. Produced in several grades, characteristics include UV, oxygen, and static resistant, one or two-side pretreatment for better ink adhesion, heat stabilized, slip treated, and fire retardant.
