Release:admin Source: Unknown  Release time:2021-05-28

Bag making machine is a machine for making all kinds of plastic bags or other material bags. There are hot bag making machine and cold cutting bag making machine in the bag making machine. The difference between them is mainly in the treatment method of the last knife, but in fact they all belong to one of the bag making machines. , there will be a heat sealing process before cutting bags, can produce vest bags, its processing range for various sizes of different thickness specifications of plastic or other materials of packaging bags, generally speaking, plastic bags as the main product.

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 seal, the prepared vest bag is more secure, generally used in supermarkets are heat seal and hot-cutting vest bag. On the other hand, the hot sealing and cold cutting bag making machine is to heat seal a knife first, and then cut off with a cold knife. 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 changing the double-line sealing knife into single-line sealing knife in the bag making machine, because its cutting edge is open type.






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 very hard; In the process of curing 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 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 good anti-pollution heat sealing property, used for the packaging of products will not make the product deterioration.
