40 micron opaque blue PE silicone coated release film is commonly used in the tape industry as a release liner.

The blue color of the film provides brand recognition and product differentiation, which is an essential consideration for many tape manufacturers.

Additionally, the silicone coating on the film provides a non-stick surface for the adhesive, which facilitates easy release during tape application.

The film's thickness, at 40 microns, is suitable for a range of tape applications and provides sufficient strength and durability for most products.

Some common applications of 40 micron opaque blue PE silicone coated release film in the tape industry include:

1. Masking tape:

    The release liner is used in the production of masking tapes, where it ensures easy release of the adhesive on the tape's surface during 

    application.

2. Double-sided tape:

    The release liner is used in the manufacture of double-sided tapes, where it creates a barrier between the two adhesive surfaces, enabling

    easy separation during application.

3. Duct tape:

    The release liner is also used in the manufacture of duct tapes, where it ensures easy release during application, enabling the tape to adhere 

    firmly to the surface.

4. Adhesive films:

    The release liner is used in the manufacture of adhesive films for various industrial applications, such as surface protection and insulation.

In summary, 40 micron opaque blue PE silicone coated release film is commonly used in the tape industry for its distinctive blue color, which

provides brand recognition and product differentiation. The film's thickness and silicone coating ensure easy release of adhesive during

application, making it an ideal choice for tape manufacturers.

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.
