80 μm opaque blue PE release film, silicone UV cured, for protective and packaging, tapes, labeling and graphics
An 80-micron opaque blue PE (polyethylene) silicone-coated release film can be used in various applications where a protective and release liner is required. Some of the common applications for this type of film include:
Adhesive Tapes: The release film can be used as a liner for adhesive tapes, providing a smooth and non-stick surface that allows the tape to be easily removed and applied.
Labels and Stickers: It can be used as a liner for labels and stickers, allowing for easy application and removal without damaging the adhesive or the surface it is applied to.
Graphic Films: The release film can be used as a protective liner for graphic films, such as vinyl or polyester films used for signage and vehicle wraps. It protects the adhesive side of the film during storage, transportation, and application.
Medical Applications: The film can be used as a liner for medical devices, such as wound dressings or transdermal patches. It provides a sterile and non-stick surface that allows for easy application and removal without causing discomfort to the patient.
Industrial Applications: The release film can be used in various industrial processes where a protective liner is required, such as in the manufacturing of composites, laminates, or other materials. It prevents sticking or damage during processing and can be easily removed afterward.
It's important to note that while these applications are common, the specific use of the 80-micron opaque blue PE silicone-coated release film can vary depending on the manufacturer and their intended purpose for the product. It's always recommended to consult the product specifications or contact the manufacturer for specific information regarding its recommended applications.

Coating silicone onto the surface of polyethylene film typically involves a process called silicone coating or silicone lamination. Here's a general overview of the steps involved:
Surface Preparation: Ensure that the polyethylene film surface is clean and free from any dust, dirt, or contaminants. This can be done by wiping the surface with a clean cloth or using a solvent that is compatible with polyethylene, such as isopropyl alcohol.
Silicone Coating Solution: Prepare a silicone coating solution or dispersion. This typically involves mixing a silicone polymer or silicone emulsion with a suitable solvent or carrier. The specific formulation will depend on the desired properties of the silicone coating, such as its thickness, adhesion, and flexibility.
Coating Application: Apply the silicone coating solution onto the polyethylene film surface. This can be done using various methods, including:
Roll Coating: The film is passed through a set of coating rollers or a coating machine, where the silicone coating solution is applied evenly onto the film surface.
Spray Coating: The silicone coating solution is sprayed onto the film surface using a spray nozzle or a spray coating machine. This method allows for more precise control over the coating thickness.
Knife Coating: The silicone coating solution is applied onto the film surface using a knife or a blade, which spreads the solution evenly across the film.
Drying or Curing: After the silicone coating is applied, the coated film needs to be dried or cured to allow the silicone to adhere and form a stable coating. This can be achieved by passing the film through a drying oven or using other curing methods specified by the silicone manufacturer. The drying or curing temperature and duration will depend on the specific silicone coating used.
Quality Control: Once the coating is dried or cured, it's important to inspect the coated film for any defects or inconsistencies. This may involve visual inspection, measuring the coating thickness, or conducting adhesion tests to ensure the desired quality of the silicone coating.
It's worth noting that the specific process and equipment required for silicone coating can vary depending on the scale of production and the specific requirements of the coating application. It's recommended to consult with a silicone coating manufacturer or supplier for detailed guidance and to ensure the process is carried out properly and safely.
