Matte release film is a very good high-end compression isolation material with high filling and temperature resistance, high tensile and tear strength, chemical inertness, and no adhesion.

Matte release film is based on the original PET transparent film, with appropriate adjustments to the raw material formula and the addition of silicon dioxide, so that the surface of the film has appropriate roughness. Then evenly apply 0.2um-0.6um release silicone oil on the surface of the polyester film after drying.

Matte release film makes the surface of the product smooth and smooth, with uniform coating, high cleanliness, stable release force, and good adhesive tape residue. The matte release film should not have defects such as wrinkles, tears, particles, bubbles, pinholes, etc. when selecting the PET matte original film.

What are the functions of matte release film? Matte release film is mainly used for FPC flexible circuit boards, die-cutting industry, food packaging, and automotive insulation.

The thickness of the matte film is 25um, 30um, 36um, 38um, 50um, 75um, 100um, 125um, 188um.

When fast pressing FPC flexible circuit boards, it is necessary to cut the matte release film into a more suitable size. It is generally recommended to cut it to T: 35 μ M × W: 280mm × L: 350mm, can also be adjusted according to the size of the FPC layout design, or reasonably optimized and combined according to the existing equipment table specifications.

The matte release film adopts manual and mechanical cutting methods. Regardless of the matte release film being cut, it must be operated in a dust-free, constant temperature, and humidity free working environment. Operators must wear dust-free protective equipment and their skin must not come into direct contact with the product.

Mechanical cutting of matte release film often uses a flat tension cutting machine. The biggest advantage of flat load cutting and matte release film cutting is its adjustable size and fast speed. A machine can cut up to 30000 pieces per day with accurate accuracy.

The flat cutting machine must place one or two demagnetizing rods, one on the cutting edge and the other at the feeding location. The demagnetizing rod must be in contact with the ground, otherwise it will not work.

In addition, the flat tension cutting machine is also designed with 4-6 sticky dust wheels, and the sticky dust film is placed on the sticky dust wheel to remove dust from the matte release film. After a period of use, the dust film on the dust wheel will be replaced. It is recommended that the viscosity of the sticky dust film be around 30 grams, not too large, otherwise the machine will not rotate. It cannot be too small, it cannot remove dust.

It is a very good high-end compression isolation material with high filling and temperature resistance, high tensile and tear strength, chemical inertness, and no adhesion.

Matte release film can completely replace copper foil and TPX adhesive blocking film; Save a lot of material and labor costs, improve production capacity and efficiency; It is an excellent release material in the production of multi-layer boards. Due to its unique and diverse properties, it is also an ideal laminated isolation material for many soft circuit boards (FPCs).

The matte release film can be used for long-term high-temperature operations at 180-220 ℃. FR-4 multilayer board for lamination. It is recommended to use 500 layers of boards. Um thickness, commonly used size is T: 50 μ M × W: 1070mm × L: 1270mm, must be handled with care when using, stored in a warehouse at a temperature of 25 ℃ and 60%, and must not be close to fire, heat sources, or direct sunlight.
