How to solve the wrinkle of PP film blowing machine film?
Many films are often produced by PP film blowing machine,but wrinkles will appear in the production process,so how do we solve this situation?
First,the blowing ratio is too large,causing the membrane bubble to be unstable,swing left and right,and prone to wrinkles
Solution:reduce the expansion ratio appropriately.
Second,the cooling effect is not enough
It can improve the cooling effect of PP film blowing machine and ensure that the film can be fully cooled.
Third,the angle of the herringbone splint is too large,and the membrane bubble is flattened in a short distance,so the membrane is also prone to wrinkles
Solution:appropriately reduce the included angle of herringbone splint
Fourth,the film thickness is uneven
Adjust the thickness of the film to ensure uniform thickness.
Fifth,the pressure on both sides of the traction roller is inconsistent,high on one side and low on the other
Solution:adjust the pressure of the traction roller to ensure that the film is stressed evenly.
Therefore,the wrinkle of PP film blowing machine needs to be solved with correct methods to ensure the quality of products
