The three-side sealing bag making machine needs to heat seal a knife first, and then cut it off eagerly. The edge after cutting is heat sealed. Generally, the vest bag used in the supermarket is heat sealed and eager. Bag making machine is first heat seal a knife, and then cut with a cold knife, cut the edge is open. In addition to the vest bag production, it can be used for double line sealing knife into single line sealing knife, also can be used in the production of flat pocket, because its cutting edge is open type.

In the process of using three-side sealing bag making machine, ionic resin can be selected because of the use of anti-pollution heat sealing film with good matching, because it has good anti-pollution heat sealing properties, used for packaging products will not make the product deteriorate.

Sometimes the products of bag-making machine will appear brittle or brittle, the main reason is nothing more than that the heat sealing is too high and too large; The heat sealing time is too long; The edge of the upper part is too sharp; The silicon at the bottom is hard; In the process of and curing, part of the infiltration into the film and so on. Due to the influence of penetration, the toughness of the substrate decreases and the brittle fracture is strengthened.

In order to solve this problem, according to the different materials of the inner sealing layer, suitable processing and heat sealing time should be selected for the three-side sealing bag making machine; And improve the upper heat sealing knife plane state, make the surface smooth; Also choose suitable hardness of silicon pad, so as to ensure bag quality.
