Film Grade Base Polyester Chips

PET Chips, also known as Polyester Chips or Polyethylene Terephthalate Chips is the base of any type of plastics & polymer. Depending on the processing, PET may exist both as an amorphous (transparent) commonly known as Bright or Super Bright Chips and as a semi-crystalline material commonly known as PET Semi-Dull Chips.PET Chips are also used to make PET Film. High quality chips without Silica & CiO2 contents are used to make PET Film.

The Film grade polyester chips are commonly available in Super Bright and Additive (Silica) varieties. Feature of film grade PET chips is excellent clarity as the film is made in very thin specification & even the slightest mistake in raw material can be harmful to the film quality. The film is available in two types, Viz.,1.Plain (both side untreated (UT) 2.One side Corona treated film (CT), Applications of film grade pet chips are Printing & Lamination, Metallization, Embossing, Holograms, thermal lamination.
