RIGID PVC FILM
Polyethylene terephthalate (PET) film is the most common thermoplastic polymer from the polyester family, which plays a large role in various industries, including packaging, vacuum forming, thermoforming, and the printing industry, due to its ease of recycling. PET film is produced in two types, transparent and colored. One of the derivatives of PET film production is metallized PET, which is available in different colors. Pharmaceutical grades of PET film are also used in the pharmaceutical industry in laminated form.
PET film is used as one of the most popular materials in the packaging industry due to its unique physical and chemical properties such as high impact resistance, high transparency, thermal stability and recyclability. In the food and beverage packaging industry, PET film has a special place due to its non-reactivity with the internal contents and maintaining the freshness and quality of the product.

Chemical properties
In addition, PET film is also used in other industries such as the electronics industry and the production of automobile parts. In the electronics industry, PET film is used as electrical insulation and in the production of display screens. In the automotive industry, PET film is used in the production of internal car parts due to its high resistance to heat and chemicals.
In the automotive industry, PET film is used in the production of internal car parts due to its high resistance to heat and chemicals. Also, special grades of PET film are produced for use in specific environments such as medical and pharmaceutical environments. These grades are used laminated with other materials to create better protective and hygienic properties.
PET film also has an environmental advantage over many other materials because it can be easily recycled and reused in new products. These features have made PET film one of the best options for use in various industries.
