80 μm opaque green PE release film, silicone UV cured, for protective and packaging, tapes, labeling and graphics
The 80 micron opaque green PE silicone coated release film is ideal for applications that require a thicker release liner.
It is commonly used in the automotive industry for creating paint protection films, vinyl graphics, and other protective coatings as it provides extra protection and durability against scratches and other types of damage. The release film is also used in building and construction applications for creating protective films for windows and doors, roofing systems, and other building materials. For medical products such as wound dressings, transdermal drug delivery systems, and medical tapes, the release film provides extra cushioning and support while still allowing for easy and gentle release of the adhesive.
In labeling applications, it provides extra durability and rigidity to prevent the labels from tearing or wrinkling during application.
Overall, 80 micron opaque green PE silicone coated release film provides extra thickness and durability when required to protect or provide extra support for the adhesive product.
The process of coating silicone on the surface of PE film involves several steps. The surface of the PE film is first prepared to ensure good adhesion of the silicone coating. The silicone is then applied to the surface of the film using a wide range of methods, including spraying, dipping, or roll coating. Once the silicone has been applied to the film, it needs time to cure, which is commonly done at a high temperature above 120°C. After curing, the coated PE film is trimmed to the desired shape using specialized equipment.
UV curing has become increasingly popular for silicone coating on PE film in recent years. Compared to heat curing, the UV curing method is faster, energy-efficient, and eco-friendly. It results in a uniform and high-quality silicone coating with excellent adhesion and chemical resistance, and it saves time, resulting in faster production times. Unlike heat curing, the UV-curing process uses light waves in the ultraviolet spectrum, 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. This process involves determining the desired release ratio, adjusting the coating weight of each side, conducting testing, and adjusting the coating weight as needed until the desired release ratio is achieved. It is essential to establish clear plan process parameters to control the symmetrical release ratio. The amount of silicone coating applied, the temperature used, and the solvent system used can all be regulated to control the specified release level or ratio of both sides of PE film.
