How to solve the problem if the woven bag curls
Product Details
If the woven bag after hot pressing is cut after less than 24 hours, it is easy to bend. The relative solution is actually very simple. After this problem occurs, we should select the self-sealing bag surface substrate film, adjust the tension of each part of the composite processing equipment, and make the shrinkage of the two composite substrates equal as much as possible. Secondly, we can adjust the tension of the floating roller, and select the inner sealing substrate with low temperature heat sealing property, Adjust the heat seal temperature to a suitable temperature. It is important to fully cool and ripen the material before entering the heat-sealing process when producing color printing woven bags, so that the problem of warping will not occur.
