Release coated films are thin films (often polyester, polypropylene, or PTFE-based) treated with a release coating such as silicone. This coating prevents adhesives, resins, or sticky materials from permanently bonding to the film, making them ideal for process protection, lamination, and clean release applications.

🛠️ Key Uses of Release Coated Films

• Adhesive Processing
  • Used as liners for double-sided tapes, labels, and transfer adhesives.
  • Prevents premature sticking and ensures clean release during application.
• Composite Manufacturing
  • Acts as a release layer in resin infusion, prepreg layup, and lamination.
  • Ensures smooth separation of cured composites from moulds.
• Packaging & Industrial Processes
  • Provides non-stick surfaces in heat sealing, lamination, and extrusion.
  • Protects rollers, belts, and surfaces from adhesive buildup.
• Electronics & Electrical
  • Serves as release liners for insulation films, foils, and adhesive components.
  • Used in capacitor and transformer manufacturing.
• Medical & Hygiene Products
  • Release liners for medical dressings, wound care adhesives, and hygiene products.
• Printing & Graphics
  • Used in decal, sticker, and label production to carry adhesive layers until transfer.

✅ Benefits of Release Coated Films

• Non-Stick Surface: Prevents adhesives and resins from bonding permanently.
• Clean Release: Ensures smooth separation without residue.
• Heat & Chemical Resistance: Performs reliably in demanding industrial environments.
• Durability: Strong film backing resists tearing and stretching.
• Versatility: Available in multiple film types (PET, PP, PTFE) for tailored performance.
