What it concludes

ESTAR film support is made from polyethylene terephthalate (PET) polymer, providing high strength and durability.
The film manufacturing process requires three primary stages: support creation, light sensitivity emulsion application, and packaging.
Extrusion screws use a changing gap design to compress, melt, and remove volatile gases from the polymer material.
Tenter and drafting processes stretch the film in both dimensions to align polymer molecules and add strength.
