The film made of film blower has good barrier property, preservative, damp proof, frost proof, oxygen proof and oil resistance, and can be widely used in light and heavy packaging. It is widely used in various fields such as fresh fruit, meat, pickles, fresh milk, liquid drink, medical supplies and so on. In order to facilitate the film blowing and normal blowing, the temperature of the blowing machine needs a best temperature, and how the temperature will be controlled.
With the increasing demand of the market, the technical requirements for the film blowing machine are increased. But the domestic PE film blowing machine has not yet reached the market demand. In the production technology of the high end film blowing machine, China has not yet reached the level of the developed countries. Nowadays, traditional plastic film is no longer able to meet the requirements of high-grade commodity packaging. The multi-layer co extrusion composite film blown by blow molding machine has been favored by people.
With the rising of the soft packaging industry, the technology level of the blown film machine of the blown film machine has been fully developed in the market. Now the blown film of blown film machine is applied in the high-end packaging industry, and has reached sixteen percent international level.
The use of high pressure polyethylene blown film machine, film blowing machine manufacturer (LDPE) or low pressure polyethylene (HDPE), after heating, extrusion, blowing, stretching and coiling of cylindrical film, made by cutting and sealing lining bag for food packaging bags, shopping bags or woven bags, unilateral or on both sides is cut, roll after doing film, film and film.
In order to get the plastic bag product with controllable quality in the process of processing, the processing links should be controlled in place. In general, the processing process of the film blowing machine is divided into heating, pulling and controlling the edge of the air pressure. After adding gas to the membrane head and adding gas to the middle of the circular membrane, the film is straight up. The size of the plastic bag is controlled by how much air is blown, then the film is stabilized by the film stabilizing device.
