Problem & Solution

1)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.

2)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.

3) Defect after cutting curly products
