A After some special treatment, bopet film will be more outstanding in some aspects. For example, after coronal treatment, bopet film will become more suitable for printing.

A Excellent transparency:
Bopet film has good light transmittance, and the optical fiber will only be slightly damaged when passing through it.

Mechincal strength:
Due to the particularity of its molecular structure, bopet film has good mechanical strength, which enables it to play a role in many fields.

Environmention firendly and recycled:
Compared with metal foil and other professional packaging films, bopet film is more environmentally friendly and produces less pollution in production and recycling.

Thermal stablity:
The melting point of bopet film is above 150 degrees Celsius, which makes it very heat-resistant, able to keep its shape in most cases, and can be used as a heat seal for products.

A BOPET film (biaxially oriented polyester film) has good recyclability. According to cases from many companies and research institutions, even films that are composited with BOPET and other plastic layers can be recycled.

A First, the PET resin is dried to remove moisture and impurities from the resin. Second, the dried PET resin is melted at high temperature and evenly extruded through a flat coating head to form an amorphous film. Third, the cast film is longitudinally stretched at high temperature to orient the molecular chains along the mechanical direction. Fourth, the longitudinally stretched film is transversely stretched at high temperature to orient the molecular chains in the cross-sectional direction, thereby obtaining biaxially oriented properties. Fifth, the biaxially oriented film is thermally cured to stabilize the structure and give it final performance. Finally, the film is rolled up and slit into various specifications as needed.

A Bopet film is a biaxially stretched polyester film, mainly made of polyethylene terephthalate through biaxial stretching. It has the advantages of excellent heat resistance, chemical stability, optical transparency and mechanical strength.
