2. Solutions
Check and adjust the guide roller (such as offset roller, offset roller, etc.), adjust the tension of the double float roller.

Two, paper bag machine cover with spots, bubbles
The cover is speckled, bubble refers to the sealing surface is not flat
1. Occurrence factors
Heat seal knife or heat seal silicone pad uneven.
Bubbles occur when the hygroscopic material structure rich in nylon film is heat-sealed.
Lack of heat sealing pressure.
Use one - component adhesives, such as neoprene adhesives, when making bags by heat sealing. Hot covers are prone to uneven pits.
2. Solutions
Replace adhesive.
View or adjust the heat seal knife and heat seal silicone pad.
