Production Process

Tradsark uses advanced vacuum metallization technology to produce aluminized polyester films:

1. PET Film Base – High-quality PET film is prepared with excellent mechanical and thermal properties.

2. Vacuum Aluminum Deposition – Pure aluminum is evaporated in a high-vacuum chamber.

3. Condensation on PET Film – Aluminum atoms are deposited evenly onto the PET film surface.

4. Finishing & Slitting – The film is cooled, inspected, and slit into required widths and thicknesses.

5. Quality Testing – Each batch is tested for barrier properties, coating adhesion, and strength.

This process ensures a uniform aluminum coating with excellent reflectivity, barrier performance, and durability.
