They are clear, flexible, transparent or translucent material produced from PET polymer, a linear, thermoplastic polyester resin. PET film is a high-performance polymeric film and is generally more expensive than other polymeric films with several unique properties that are required for various end-uses. PET film has certain inherent desirable qualities such as high tensile strength, durability, heat resistance, good gas-barrier properties, dimensional stability, chemical inertness and clarity. PET film is available commercially in a range of widths, thicknesses and properties depending upon the needs of end users. It can be made as a single layer or can be coextruded with other co-polymers into a multilayer film encompassing the desired characteristics of each material. The distinct physical properties of the various types of PET film can be imparted into the product either during the polymerization of the PET resin, by the addition of chemicals such as slip modifiers (surface modifiers) or color additives, or subsequently during the PET film production process where various surface finishes may also be imparted by externally treating the films' surface(s).The biaxial orientation of the PET film makes it suitable for such applications as food packaging, electrical insulation, and printing sheets by increasing the product's crystallinity and thereby improving its tensile strength, heat resistance, and gas-barrier properties.
BOPET - Thin Film
All these years, Polyplex was predominantly operating only in thin PET films. The largest application of thin PET films is flexible packaging.
BOPET - Thick Industrial
Polyplex thick PET film segment with a thickness range of 23 to 350µ. Thick PET film is suitable for various Display, PV, Electrical and Industrial applications. Sarafil Thick film produced with strict quality and cleanness norms:
- Cleanroom condition for super clear PET films (Class 1000/10000)
- Low MD shrinkage(<1.0%) capability
- Web inspection and Auto web cleaning at TDO outlet
