Cold and hot processing method of bag making machine

There are two kinds of bag making machines: hot cutting Bag Making Machine and cold cutting Bag making machine
The difference between the cold and hot processing of bag making machine is mainly in the treatment method of one knife at the end, but in fact they all belong to a kind of bag making machine. The common ground is also quite obvious. They are all produced by barrel materials. There will be heat sealing process before bag cutting, and vest bags can be produced. Bag making machine is a kind of machine that makes all kinds of plastic bags or bags of other materials. Its processing range is bags of various sizes, thicknesses and specifications of plastic or other materials. Generally speaking, plastic bags are the main products.
The hot sealing and hot sealing bag making machine needs to heat seal a knife first, and then cut it off eagerly. The cut edge is heat sealed, so the prepared vest bag is more secure. Generally, the hot sealing vest bag is used in supermarkets. The heat sealing and cold cutting bag making machine is to heat seal a knife first, then cut it with a cold knife, and the cut edge is open. In addition to being used in the production of vest bags, the bag making machine can change the double line sealing knife into the single line sealing knife, and can also be used in the production of flat bags, because its cutting edge is open type.
Sometimes the bag making machine products will appear brittle or brittle fracture, the main reasons are 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 too hard; in the process of aging, a part of it seeps into the film. Due to the influence of penetration, the toughness of the substrate decreases and the brittle fracture is improved.
In the process of using hot cutting bag making machine, due to the use of film with good anti pollution heat sealing property, ionic resin can be selected, because it has good anti pollution heat sealing property, which will not make the product deteriorate after being used in product packaging.
