With the development of flexible packaging products and gradually mature, the market competition is more and more fierce. In order to meet the needs of the market, in addition to further strengthen the quality control of printing, composite materials, more and more attention to the quality of bag-making machine. Bag-making process is the last process of plastic flexible packaging production and processing. If the bag-making quality is unqualified, it will be reprocessed at least, which wastes resources and affects production and operation at worst. Therefore, we should understand the problems encountered in the bag-making process, so as to solve them quickly and reduce the loss.

Below, take the hot sealing and cold cutting bag making machine as an example:

When the upper and lower blades begin to overlap, adjust the screw at the entrance of the blade to keep a little gap at the entrance side, because when the overlap begins, if there is no gap or the blade is used below, damage will occur. After adjusting the gap at the entrance of the blade, squeeze the screw that adjusts the knife pressure when the bag cutting effect is not good.
