We know that the non-woven bag making machine is very helpful for the production of many non-woven bags now. In the production, we should also try our best to deal with the problems of daily operation.
What should I do if the non-woven bag making machine is not completely heat-sealed and causes the contents to leak or deteriorate?
Reason: The anti-pollution heat sealing property of the film is poor, mainly because the resin used in the inner sealing layer is not suitable.
Countermeasures: Use a film with good anti-pollution heat sealability. Generally speaking, LDPE has moderate anti-pollution heat-sealability, EVA has good anti-pollution heat-seal properties when the VA content is large, LDPE also has good anti-pollution heat-seal properties, and ionic resins and metallocene polymers have good anti-pollution heat-seal properties. Has excellent anti-pollution heat sealability.
What should I do if the seal of the non-woven bag making machine is brittle and brittle?
Reasons: 1. The heat sealing temperature is too high; 2. The pressure is too high; 3. The heat sealing time is too long; 4. The edge of the upper sealer is too sharp or the coated PTFE is damaged; The rubber is too hard; 6. During the compounding and curing process, a part of the adhesive penetrates into the inside of the film. Due to the influence of the penetration of the adhesive, the toughness (impact resistance) of the substrate decreases and the brittleness increases;
