1. PET Film Wrinkle
- Adjust the temperature and speed according to the environment, ensuring they are optimal.
2. Small Holes on the Surface of Both Colors and Adhesive Side
- Reduce the drying temperature if the oven temperature is too high. If possible, cure at a lower temperature for a longer time.
3. Excessive Powder Remains on the Film After Powder Removal
- Check the file and design to ensure the edge is clean and smooth in high resolution.
- Ensure the printer and applicator are well grounded.
- Maintain humidity levels above 45%.
- Ensure the use of POLYTECH products, as quality varies by manufacturer.
4. Design Details Lost
- Ensure normal heat press conditions.
- Check if the pattern lines are too thin; thin lines reduce white ink and powder volume. Expand the thin lines or the white ink area to adhere enough hot melt powder.
5. PET Film Sticks to Each Other After Curing
- Ensure reasonable curing conditions and that the cooling fans are turned on. If sticking persists, avoid winding.
