40 μm translucent white PE release film, silicone UV cured, for protective and packaging, tapes, labeling and graphics

Translucent white PE silicone coated release film is a type of release liner that has a layer of silicone adhesive applied to one side of a

polyethylene film. Here are some primary uses of translucent white PE silicone coated release film:

1. Protective and packaging applications:

Translucent white PE silicone coated release film is often used as a protective layer in applications where surface protection is required.

For instance, it is commonly used to protect surfaces, such as plastic sheets, from scratches and other damages during storage or

transportation.

2. Labeling and graphics applications:

Translucent white PE silicone coated release film is also frequently used as a release liner for adhesive labels or stickers.

It can be printed with high-quality graphics, such as logos and designs.

3. Thermal lamination applications:

Translucent white PE silicone coated release film is also utilized in thermal lamination where the film is heated and applied to paper to

protect the printed matter during handling.

4. Medical and healthcare applications:

Translucent white PE silicone coated release film is also used in the medical and healthcare industry for packaging of medical devices,

such as surgical instruments and equipment.

5. Automotive and electronics applications:

Translucent white PE silicone coated release film is also used in the automotive and electronics industry for the production of gaskets,

displays, and touch screens.

Overall, translucent white PE silicone coated release film provides a reliable and high-quality solution for a range of applications, including

protection, labeling, graphics, thermal lamination, medical and healthcare, automotive, and electronics applications.

Translucent white PE silicone coated release film is commonly used in the tape industry as a release liner for double-sided tapes, adhesive tapes

or labels. The use of silicone as a coating for the film provides a non-stick surface to allow the tape to be removed easily during application.

Here are some ways in which translucent white PE silicone coated release film is mainly used for the tape industry:

1. Double-Sided Tape Liner:

Translucent white PE silicone coated release film serves as a liner for double-sided tapes, protecting the adhesive layer until the time of

application. Removing the release liner ensures full contact between the tape's adhesive layer and the surface it will adhere to.

2. Adhesive Tape Liner:

Translucent white PE silicone coated release film is utilized in the adhesive tape industry to provide a protective liner for the adhesive until

it is ready to be applied.

3. Label Printing:

The translucent white PE silicone coated release film is print-compatible, making it an ideal liner to print on before the adhesive layer is applied.

This is crucial for identification or branding purposes.

4. Die-cutting:

The tape industry frequently uses die-cutting techniques to create precise shapes. For this purpose, the release liner must be easy to remove,

requiring a stable, non-tearable substrate, and translucent white PE silicone coated release film meet these criteria.

In summary, the translucent white PE silicone coated release film is commonly used as a release liner for double-sided or adhesive tapes, labels,

and printing. It offers a non-stick surface, precision cutting, and is print-compatible.

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.
