What is PET double-sided release film

What is PET double-sided release film? It is a commonly used material in the thermal transfer of PET double-sided release film. The substrate is PET, and the surface is coated with silicone oil, so it is also called silicone oil film. Normal thickness from 25um to 150um. There are hot and cold tear and matte finish. After anti-static and anti-scratch treatment, the product has good adsorption and adhesion.

ET release film is also called PET silicone oil film, which is coated with a layer of silicone oil on the surface of PET film to reduce the adhesion of PET film surface and achieve the effect of release. It can be divided into single-sided release film and double-sided release film. According to the release force, it can be divided into light release film, medium release film and heavy release film. Commonly used thickness is: 0.012mm, 0.019mm, 0.025mm, 0.038mm, 0.05mm, 0.075mm, 0.125mm, 0.188mmPET double-sided release film manufacturers are equipped with large slicer, can be rolled according to your specifications. PET double-sided release film has been widely used in packaging, printing, screen printing, pad printing, inscriptions, film switches, flexible circuits, insulation products, circuit boards, laser anti-counterfeiting, adhesives, electronics, sealing materials, reflective materials, waterproof materials, medicine (plaster paper), toilet paper, adhesive products, die cutting and stamping.

Membrane separation

PET double-sided release film is also called thermal transfer film, release film, isolation film, synovial film, Tenna paper, silicone oil film, anti-mucous membrane, silicone oil release paper, silicone oil paper, facial mask, PET double-sided release film is also called PET transfer film. Mainly used as a carrier for vacuum aluminum plating, that is, after the PET film is aluminized in the vacuum aluminum plating machine, it is coated with glue and paper composite, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the cardboard through adhesive, forming the so-called aluminized cardboard. The production process of aluminized cardboard is: PET base film release layer color layer aluminized coating layer transferred to the cardboard.

In addition to the excellent physical and mechanical properties of ordinary polyester film, PET double-sided release film also has excellent optical properties, such as good transparency, low fog and high gloss. Mainly used for high-grade vacuum aluminized products. After aluminum plating, the film is mirror-like, with good packaging and decorative effects. It can also be used for laser anti-counterfeiting base film. The BOPET film market has large capacity, high added value and obvious economic benefits.

Transfer film, also known as thermal transfer film, is characterized by high tensile strength, good thermal stability, low thermal shrinkage, smooth surface, good stripping performance, and reusable.

Vacuum aluminized paperboard is a kind of paperboard with metallic luster, which is an advanced new packaging material developed in recent years. This aluminized cardboard is bright in color, strong in metal, bright and elegant in printed matter, can replace printed matter with large area gilding, and play the icing on the cake of beautifying goods. Due to the vacuum aluminum plating method, the surface of the cardboard is only covered with a thin and dense bright aluminum layer of 0.25um~0.3um, which is only 1/500 of the aluminum foil layer of the laminated cardboard. Therefore, it is a kind of green packaging material with noble and beautiful metal texture, degradable and recyclable environmental performance.

Today's world has entered the information age, electromagnetic waves of various frequencies and wavelengths fill the entire earth space. These electromagnetic waves can cause varying degrees of interference to unshielded sensitive electronic components, circuit boards and communication devices, causing data distortion and communication confusion. The static electricity generated by electromagnetic induction and friction will be destructive to various sensitive components, instruments, and some chemical products. For example, high voltage discharge caused by electrostatic accumulation of packaging film. Therefore, the development of anti-static PET packaging film is also very important. The antistatic film is characterized by the addition of some antistatic agents to the double-sided PET film to form a very thin conductive layer and continuous phase on the surface of the film, which can improve the surface conductivity and make the generated charge leak as soon as possible. Generally, the surface resistivity of the antistatic film is 109~11 ohms.
