Select and procure high-quality raw materials, such as polyester film, adhesives, and UV protection coatings.

Use extrusion equipment to process polymer raw materials into thin films. This involves heating the materials to a molten state and then extruding them through a die to form film sheets.

Apply various functional coatings to the base film, such as scratch-resistant coatings, UV protective layers, and adhesive layers. This step is typically performed in a cleanroom environment to prevent contamination.

Bond multiple layers of films with different properties together. This process ensures the final product has a combination of features such as strength, high transparency, and specific optical properties.

The coatings and adhesives need to be dried and cured at appropriate temperatures to ensure they adhere firmly to the film and provide long-lasting performance.

The cured film is cut into specified widths and lengths, then wound into large rolls for easier handling and transportation.

Conduct rigorous quality checks, including thickness measurement, optical testing, UV resistance tests, and tensile strength evaluations, to ensure compliance with specifications and meet expected performance standards.

Package the qualified products according to specifications, label them with batch and production information, and store them in warehouses ready for shipment.
