Polyester Films

APET (amorphous polyethylene terephthalate) is a thermal plastic composed of carbon, hydrogen, and oxygen. APET has excellent transparency and high impact strength. It also is non-toxic and has excellent gas, water, and chemical barrier properties. Typical applications of APET include vacuum forming, food packaging, folding boxes, offset printing, and screen printing.

Industrial polyester films have outstanding mechanical and dielectric strength. These films are extremely durable and dimensionally stable. They also have low water absorption and good chemical resistance and retain these properties over a wide range of temperature and humidity levels.

General-purpose polyester films are chemical and moisture resistant, with high tensile strength, dimensional stability, and working temperatures up to 400°F. These films can be heat-sealable, metalized, punched, and laminated. General-purpose polyester films come in a variety of opacities such as clear, very clear, slightly hazed, matte, translucent white, opaque white, and black.

Heat stabilized polyester film is an optically clear, glossy film with adhesion-promoting pretreatment on both sides. Heat stabilized polyester has very good adhesion to various types of inks. It also has very low heat shrinkage, and it is ideal for applications such as membrane touch switches and displays.

Print-treated polyester is an optically clear, glossy polyester film. It has been pretreated on both sides for adhesion promotion. Print-treated polyester was developed for use in applications such as window safety film, solar control film, graphic arts films, microfilms, reprographics, membrane touch switches, printed circuits, and laminates.
