The encapsulation of foils on steel, stainless steel or non-ferrous metal takes place at high temperatures when the laminating roll coatings are heavily loaded. Depending on the coating used, it can melt and become cracked or smooth.
If the wrong coating material is selected, wrinkles may form on the finished laminated product or the foil may adhere to the laminating roll, which can lead to defects on the laminated product.
High contact pressure and/or high circumferential speeds often cause damage to the laminating roll coating, such as impressions or detachment of the covering.
Problems in brief:
- The laminating rolls show melting or cracks in the surface
- The laminated product exhibits wrinkles, pits or similar damage
- The product remains stuck to the laminating roll
- Removal of coating through excessive contact pressure or too high a speed
