The difference between fully automatic and semi-automatic vest bag making machines

The three-layer co extrusion blown film machine packaging industry is a major mainstream industry in China. Food, medicine, clothing, agriculture, and other industries cannot do without packaging. Therefore, bag making machines are a form of packaging. So, what is the difference between semi-automatic and fully automatic punching bag making machines?

As the name suggests, a heat sealed and hot cut bag making machine is a machine that first seals the bag with a knife, then cuts it with a hot cut. The cut edge is heat sealed, and the made vest bag is equivalent to double safety, because most supermarkets use heat sealed and hot cut vest bags. It is a specialized machine for vest bags. If you want to diversify production, you can consider a heat sealed and cold cut bag making machine. In addition to vest bags, you can also produce outer packaging bags for hardware daily necessities - flat bags

In addition to these two types of machines, there is also a hot cut edge sealing bag making machine. When I saw a friend answer earlier, I confused these two types of machines. Blowing film technology tip: Blowing film is actually a thin film between biaxial oriented film and cast film.

Double axis oriented films can also be produced using the blowing expansion method. As long as the temperature is appropriate, the blowing expansion ratio and traction ratio are appropriate, the bi-directional orientation can be roughly the same. When producing blow blown film, if the traction speed is too fast and the difference between the same blow blown ratio is too large, there may be a significant difference in longitudinal and transverse orientation. It is necessary to clarify the type of bag making machine,

At present, the main bag making machines on the market include plastic bag making machines, non-woven fabric bag making machines, pearl cotton bag making machines, EPE bag making machines, chain clip bag making machines, multi-functional blow blown film bag making and printing integrated machines, etc. It is necessary to clarify which type of machine you are making and how to solve raw material problems. Understanding these problems can avoid many problems that may arise in the future when starting a factory.
