36 μm Clear PET non silicone coated release film for electronics, medical, automotive and printing etc.
The 36 μm clear PET non-silicone coated release film is commonly used in various application scenarios where a transparent and reliable release liner is required. Here are some typical uses:
Adhesive Tape and Label Production: The 36 μm clear PET non-silicone coated release film is commonly employed in the manufacturing of adhesive tapes and labels. It acts as a transparent and non-stick backing, facilitating easy release of the adhesive material during application. The clear PET film allows for visibility of the adhesive and printed content, ensuring accurate alignment and positioning.
Graphic Overlays and Membrane Switches: This release film finds application in the production of graphic overlays and membrane switches used in electronic devices, control panels, or touchscreens. It serves as a protective layer during manufacturing and assembly, enabling precise alignment of graphic elements. The clear PET film ensures optical clarity and visibility of printed designs or touch-sensitive components.
Pressure-Sensitive Product Protection: The 36 μm clear PET non-silicone coated release film is commonly used to protect pressure-sensitive products, such as adhesive films, tapes, or foam pads. It acts as a temporary protective layer during transportation, storage, or handling, facilitating easy application of the pressure-sensitive product. The transparent nature of the film allows for accurate positioning and alignment.
Surface Protection and Masking: This release film is frequently utilized in surface protection and masking applications. It can be applied to various surfaces, including glass, metal, or plastic, to safeguard against scratches, dirt, or damage during handling, fabrication, or painting processes. The clear PET film allows for visual inspection of the protected surface while ensuring easy removal without leaving adhesive residue.
Film and Sheet Manufacturing: The 36 μm clear PET non-silicone coated release film finds application in the manufacturing of films and sheets. It can serve as a release liner or interleaf layer between layers of material during production, preventing adhesion or damage. The clear film allows for visual inspection and quality control throughout the manufacturing process.
Please note that the specific suitability of the 36 μm clear PET non-silicone coated release film for a particular application should be verified based on industry requirements, manufacturer guidelines, and customization options available.
Besides, the application of non-silicon release film is mainly based on two points:
1. It does not contain silicon, so there are no issues with silicon transfer contamination.
2. It is compatible with silicone and gel, and is cheaper than fluorine-coated film
(although the release effect is not as good as fluorine-coated film).
