Matte blue release film is based on the original PET transparent film. After adjusting the raw material formula and adding silica, apply silicon or fluorine to the surface of the film to make the blue release film non stick or slightly stick when in contact with specific materials under limited conditions. TPX matte blue release film is mainly used for FPC flexible printed circuit boards, die-cutting industry, outer packaging, and automotive insulation.

Blue release film production:

PET blue release film is also called heat transfer film, heat insulation film, synovial film, Tiannan paper, silicone oil film, anti mucous membrane, silicone oil release paper, silicone oil paper, hole facial mask, and PET blue release film is also called PET transfer film. It mainly uses the carrier of vacuum aluminum plating, which involves placing PET film into a vacuum aluminum plating machine for aluminum plating, gluing, and laminating with paper. Then, the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the cardboard through gluing, forming the so-called aluminum plated cardboard. The production process of aluminized cardboard is as follows: PET substrate → release layer → color layer → aluminized layer → adhesive layer → transfer to the cardboard.

Characteristics of blue release film:

1. Using PET as the substrate, the film surface is smooth and flat, evenly coated, and free from defects such as wrinkles, tears, bubbles, and vacuum.

2. It has good high-temperature resistance, dimensional stability, and the characteristics of double-sided demolding during pressing, as well as good flame retardancy and filling performance. It is the preferred material for pressing and isolating high-end PCB precision circuits.

3. Matte blue release film has high tensile and tear strength, chemical inertness, and non stick properties, making it an excellent release material for multi-layer board production.

Attention: Storage time: It is recommended to use within 3 months. Storage environment: Try to be dry and avoid open flames.
