The scope of application of film blowing machine is mainly according to the different material and set, such as the ABA film blowing machine output film is suitable for all kinds of shopping bags, bags and other bacteria on the tensile and hardness of high brightness and other requirements of the bag, and high pressure PE blown film is suitable for all kinds of plastic bags, feed back the film is suitable for all kinds of garbage bags and so on, film blowing machine is widely used in various industries.
At present, the popular packaging in the market is mainly plastic and paper, the blow molding plastics based on plastic film blowing machine is larger in the market. With the increasingly stringent requirements for paper industry, the new indicators of environmental protection and energy saving have improved the threshold of paper industry, resulting in the expansion of the cost of paper packaging market and the rise in prices. This makes the share of plastic packaging in the market increased accordingly, stimulated the development of blown film manufacturing machinery industry.
Nowadays, blown film machine develops high-end technology, blown film can also be used as food preservation and other application technology, take the new blown film machinery manufacturing road. Blown film blow out of a special film, the use of advanced technology, so that fruits and vegetables durable. The quality of blown film machine and blown film technology determine the quality of film forming. Therefore, a good performance of blown film machine in the production of film in the process of showing a good market adaptability, improve production efficiency at the same time, to provide convenience for people, and promote social harmony and development. Blown film machine is film, suitable for all kinds of high grade film packaging. Because of its good barrier property, fresh film, moisture proof, frost proof, oxygen resistant and oil resistant, it can be widely used in light and heavy packaging.
In the film blowing machine feeding section entrance, to a lower temperature, prevent the resin viscous flow inlet is blocked, in addition, continuous feeding in the compressed air to pour Duan Shuzhi, discharged from the feed port. According to the structure of blown film machine, the price of high quality film blowing machine, although the feeding port is not electrically heated, the operation steps of blown film machine, but through the barrel heat transfer, the feed port temperature is about 50-90 degrees. In this way, the temperature of the feed section is determined. At the entrance of 50-90 degrees, the end is equal to the melting point or viscous flow temperature, blowing machine, in this section can be defined as temperature, geometric linear heating.
