How To Make Transparent PET Film?

Polymerization

plain polyester film is made by polymerization of Purified Terephthalic Acid (PTA) and Monoethylene Glycol (MEG) under specific temperatures and pressure to form PET pellets.

Extrusion and dyeing

The PET pellets are then melted down and pushed through a dyeing machine to obtain a flat sheet.

Orientation

The next step involves stretching the clear polyester film sheets to align the molecules to make it stronger and more stable. Two methods of orientation are Tentering and Bubble blowing.

Thermal Finishing

The oriented PET film is annealed or treated with heat to stabilize the film and acquire its properties.  The film is cooled and rolled into large spools to be further processed or cut as per the requirement.
