Transparent PET/APET Film for Printing and Thermoforming

Polyethylene Terephthalate Film (PET Film)

Polyethylene Terephthalate Film (PET Film) is the most common thermoplastic polymer resin of the polyester family. It is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing and in combination with glass fiber for engineering resins.

Polyethylene Terephthalate (PET) Film

PET is an excellent water and moisture barrier material,making it widely used in plastic bottles for soft drinks. For certain specialty bottles, such as those designated for beer containment, PET sandwiches an additional polyvinyl alcohol (PVOH) layer to further reduce its oxygen permeability.

Biaxially oriented PET film (often known by one of its trade names, “Mylar”) can be aluminized by evaporating a thin film of metal onto it to reduce its permeability, and to make it reflective and opaque (MPET). These properties are useful in many applications, including flexible food packaging and thermal insulation. See: “space blankets”. Due to its high mechanical strength, polyester film/PET film is often used in tape applications, such as the carrier for magnetic tape or backing for pressure-sensitive adhesive tapes.

Non-oriented PET sheet can be thermoformed to make packaging trays and blister packs. If crystallizable PET is used, the trays can be used for frozen dinners, since they withstand both freezing and oven baking temperatures. Opposed to amorphous PET, which is transparent, crystallizable PET or CPET tends to be black in colour.

When filled with glass particles or fibers, PET becomes significantly stiffer and more durable.

Our polyester films can be used for a variety of end uses. PET is also used as a substrate in thin film solar cells
