Three side sealing bag making machine is divided into hot-cutting bag making machine and cold cutting bag making machine. The difference between them is mainly in the treatment method of the last cut, but in fact they all belong to one kind of bag making machine. The common ground is also quite obvious. They are all produced with cylinder material. There is a heat sealing process before cutting the bag, and they can produce the vest bag.

Heat-sealing and hot-cutting bag making machine needs to heat seal one knife first, and then hot cut off. The cut edge is heat sealed, and the prepared vest bag is more secure. Generally, the vest bag used in supermarkets is heat sealed and hot-cutting. While the hot sealing and cold cutting bag making machine is to heat seal a knife first, and then cut off with a cold knife, and the edge after cutting is open. It can not only be used in the production of vest bags, but also in the production of flat pockets by replacing the double-line sealing knife with the single-line sealing knife in the bag making machine, because its cutting edge is open.

In the process of using hot bag making machine, because of the use of anti-pollution heat sealing film and matching, you can choose the ion resin, because it has excellent anti-pollution heat sealing properties, used for the packaging of products will not make the product deterioration.

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

In order to improve this problem, we should choose the appropriate processing and heat sealing time for the bag making machine according to the different materials of the inner sealing layer; And effectively improve the upper heat sealing cutter plane state, make the surface smooth; Also choose the right hardness of the silicon pad, so as to ensure the quality of the bag.

In the process of three-side sealing bag making mechanism, the suitable cutter plays a crucial role. The so-called suitability, of course, requires that the material, shape and installation position of the cutter can meet the bag making requirements of the bag making machine. The key to analyze here is the selection of bag making machine tool materials.
