– How to avoid wrinkles during the production process of stretch film –
As one of the top 3 china stretch film manufacturers, will share with you to see what problems need our attention. Let’s take a look together.
- The thickness of the substrate of the stretched film is not uniform, and the difference between the thickness and the thickness is too large, or the position of the substrate is skewed, causing the composite film to wrinkle.
- Improper tension setting and control, or improper compound pressure setting.
- The axis between the silicone rubber pressure roller and the cooling steel roller is not parallel.
- The surface of the guide roller is not clean, sticking foreign objects, or the surface of the guide roller is uneven, and there are pits, scratches, scratches and other phenomena.
- The aluminized layer transfer will occur during aluminizing, and the coating layer transfer will occur during the coating. The main measure to prevent the corona on the reverse side of the stretched film is to adjust the pressure of the rubber pressure roller before the corona treatment roller. The pressure on both ends of the pressure roller must be consistent and the pressure should be appropriate.
