What to Do If Aluminum Sheet Protective Film Prone to Warping in Winter
2025-09-22
Core Causes of Warping in Winter
- Low temperatures reduce film flexibility and weaken the adhesive layer
- Large indoor-outdoor temperature differences cause condensation on aluminum surfaces
- Residual dust further weakens adhesive adhesion
- Improper application techniques increase warping risk
Environment and Tool Preparation
- Store protective film at room temperature before application to restore flexibility
- Gently raise aluminum surface temperature if too cold (use room-temperature dry cloth)
- Prepare soft scraper, clean dry cloth, and neutral detergent
- Ensure aluminum surface is free of dust, moisture, and oil
Winter Application Techniques
- Precisely align one end of film with aluminum edge and press firmly
- Slowly extend film toward other end while using scraper to press from center to sides
- Ensure no air bubbles remain between film and plate
- Repeatedly press edges with scraper to ensure full contact
- Gently adjust position if wrinkles appear - avoid forceful pulling
Post-Application Reinforcement
- Press protective film edges again with dry cloth, especially corners
- Use breathable tape for temporary reinforcement in extremely low temperatures
- Avoid frequent touching of protective film edges
- If edges warp slightly, press again with scraper or clean and reinforce with neutral detergent
Note: Always handle aluminum sheets and protective film carefully to prevent damage. Avoid using excessive heat when warming surfaces.
