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

40-micron opaque red PE silicone coated release film is a type of release liner used in the production of adhesive products such as tapes,

labels, and other types of coated materials. The film has a thickness of 40 microns, which makes it relatively thin, flexible, and easy to handle.

Some of the most common applications of 40-micron opaque red PE silicone coated release film include:

1. Label Industry:

    The release liner is widely used in the label industry as a backing material for self-adhesive labels for various applications such as food

    and beverage labeling, packaging, and industrial labeling. The red color of the film provides visual appeal and differentiation.

2. Graphic Art Industry:

    The release liner is used in the graphic art industry for creating vinyl graphics, cut lettering, and decals.

    The red color of the film enables the user to easily identify the liner from the adhesive side.

3. Electrical and Electronic Industry:

    The release liner is used in the electrical and electronic industry for creating protective tapes and insulating materials.

4. Automotive Industry:

    The release liner is used in the automotive industry as an inner or outer liner for double-sided tape used to attach body trims, molding,

    and other automotive parts.

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.
