120-micron opaque green PE silicone coated release film is a type of release liner that is mainly used in the production of adhesive products

that require a very strong and durable backing.

Some of the most common applications of 120-micron opaque green PE silicone coated release film include:

1. Heavy-Duty Tapes:

120-micron opaque green PE silicone coated release film is used as an inner or outer liner in the production of heavy-duty tapes,

such as duct tape, industrial masking tape, carpet tape, and other types of construction or industrial tapes. The thicker film provides extra

stability, durability, and stiffness to the tape.

2. Manufacturing of Gaskets and Seals:

120-micron opaque green PE silicone coated release film is used in the manufacturing of gaskets and seals in various industries

such as automotive, aerospace, and construction. The thicker film provides adequate stiffness and durability to the product.

3. Medical and Pharmaceutical Applications:

120-micron opaque green PE silicone coated release film is used in the manufacturing of transdermal drug delivery systems, advanced

wound care products, and other specialized medical products where a higher level of thickness and rigidity is required.

Overall, 120-micron opaque green PE silicone coated release film is mainly used in specialized applications that require a very thick, heavy,

and durable backing. The green color of the release liner provides visual appeal and helps in product differentiation.

Coating silicone on the surface of PE film involves a multi-step process that includes the following:

1. Preparation of the film:

The first step is to prepare the surface of the PE film to ensure good adhesion of the silicone coating. The film may need to be cleaned and

treated with corona discharge or plasma to enhance its surface energy.

2. Application of silicone:

The silicone can be applied to the surface of the film using a wide range of methods, including spraying, dipping, or roll coating.

A silicone solution is prepared with a specific level of viscosity and concentration so it can be applied evenly to the film.

3. Curing of silicone:

Once the silicone has been applied to the film, it needs time to cure. Most commonly curing is done at a high temperature, typically above

120°C to allow uniform curing for better curing as well as adhesion to the PE substrate.

4. Trimming or die-cutting:

After the coating is cured, the coated PE film is trimmed to the correct size or cut into the desired shape using specialized equipment.

UV curing method is becoming increasingly popular for silicone coating on PE film in recent years. The UV curing method involves the use of

UV light to initiate a chemical reaction in the silicone, which then causes it to cure and crosslink. In contrast to the heat curing method, the UV-

curing process uses light waves in the ultraviolet spectrum rather than heat.

There are some advantages to using UV curing as a method to cure silicone on PE film:

1. Faster curing time:

The UV curing method is generally faster than the heat curing method and can often cure the silicone coating in just a few seconds.

2. Energy-efficient and eco-friendly:

Since UV curing does not require high heat temperatures, it is a more energy-efficient process and has a lower carbon footprint which

makes it an eco-friendly option.

3. High-quality coating:

UV curing results in a uniform and high-quality silicone coating with excellent adhesion and chemical resistance.

4. Lesser production time:

Compared to heat curing, the UV curing process can save time, resulting in faster production times.

5. No heat damage:

UV curing on PE film does not result in any heat damage, which ensures that the substrate's properties remain intact in the production process.

The specified stripping ratio of both sides of PE film can be controlled by regulating the coating weight of the silicone coating on each side of the

film. The stripping ratio is defined as the force required to remove the silicone-coated release liner from an adhesive and is expressed numerically

as a ratio.

Here are some steps to control the specified release ratio of both sides of PE film:

1. Determine the required release ratio:

The first step is to determine the desired release ratio for each side of the PE film. This will depend on the specific application requirements.

2. Adjust the coating weight of each side:

The next step is to adjust the coating weight of the silicone on each side of the PE film.

The coating weight will determine the thickness of the silicone coating and, therefore, the release ratio.

3. Conduct testing:

Once the coating weight has been adjusted, the release ratio needs to be tested on each side of the PE film.

The use of a tensile tester or a release force tester can help measure the force required to remove the silicone coated release liner from

the adhesive.

4. Adjust coating weight as needed:

If the release ratio does not meet the specified requirements, the coating weight on each side of the PE film needs to be adjusted accordingly.

This adjustment process may need to be repeated until the desired release ratio is achieved.

It is essential to establish a clear plan or coating process parameter to control the symmetrical release ratio.

This process involves finding the optimal settings for silicone wetting and adhesion on simple process setup steps.

The amount of silicone coating applied, the temperature used, as well as the solvent system used can all be regulated to control the specified

release level or release ratio of both sides of PE film.
