Product has snow point
(1) Caused by: Rubber roll pressure is not enough; Solution: increase the pressure;
(2) Caused by: Adhesive on Laminating film is not completely melted; Solution:
Increasing the coating temperature
Increase the film and heating roller contact area, and the heat melt adhesive film will increase the degree
Reduce coating speed
(3) Caused by: Laminating film of the adhesive surface with dust; Solution: impurities, should be promptly removed.
Products with wrinkles
(1) Caused by: rubber roller too much pressure, resulting in membrane deformation; Solution: appropriately reduced pressure.
(2) Caused by: rubber roller surface damage, not smooth; Solution: replace the rubber roller
(3) Caused by: rubber roller and the pressure imbalance between the heating rollers; Solution: adjusted and have them balance
(4) Caused by: film inconsistent on both sides of the tension, or wavy edges; Solution: replace the thin films.
