        Now we will use a large number of paper bags to package items in our lives. These paper bags are automatically produced by paper bag packaging machines, which has greatly helped our commodity circulation, but there are some problems in the production of paper bag packaging machines. Warped edges are one of them. More commonly, we will find out the cause and solution of the raised edge through the following attempts.
        What is the cause of the edge of the paper bag?
        1. The thickness of the paper bag is uneven.
        2. The heat sealing temperature is too high or the heat sealing time is too long.
        3. In the longitudinal heat sealing part, the running trajectory of the composite film is not straight.
        4. The heat resistance of the film in the composite material is poor.
        5. Inappropriate tension matching control of the composite substrate during the composite processing process leads to the maturation of the composite material and residual stress after solidification, especially when the thickness of the composite film is thin.
        Now we know why the raised edges appear. Let's set about solving this problem.
        1. Adjust the tension of the floating roller.
        2. Use low temperature sealing and heat sealing inner sealing materials.
        3. Adjust the heat-sealing temperature to a suitable temperature.
        4. Reselect the surface base film;
        5. Adjust the tension of each part of the composite processing equipment so that the shrinkage of the two composite substrates is as equal as possible.

        It is precisely because we now realize the convenience and environmental protection of paper bags that our paper bag machine manufacturers are constantly innovating in order to grow and strengthen ourselves in this highly competitive market; China ’s packaging market has great potential and development. T-space only if we are ready to meet the greater challenges of the future.
