Dalian Blowing Film Unit Tells You Tips for Blowing Film Technology

Dalian Blowing Film Unit tells you the tips for blowing film technology: 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 blown bulging films, if the traction speed is too fast and the difference between the same blown bulging ratio is too large, it may result in a significant difference between the longitudinal and transverse orientations. As a result, like the process of producing cracked fibers through unidirectional stretching, the transverse strength is low and it is easy to break. The prevention method is to appropriately reduce the traction speed to match the inflation ratio; Increase the air volume of the wind ring to quickly cool the blown expansion film and avoid being stretched and oriented at higher temperatures and high elastic states.

So a high-performance film blowing machine demonstrates good market adaptability in the process of producing films, improves production efficiency, provides convenience for people, and promotes social harmony and development. Food packaging is a field with a wide range of film applications, and the high-end film blown out by the film blowing machine can be used for product packaging promotion, enhancing commercial value. At present, the popular packaging in the market is mainly made of plastic and paper. The blow molding industry, which is mainly based on plastic film blowing machines, has a large proportion in the market. However, with the increasingly strict requirements for the paper making industry, new environmental and energy-saving indicators have raised the threshold for the paper making industry, causing the cost of the paper packaging market to expand and prices to rise.

This has led to a corresponding increase in the market share of plastic packaging, stimulating the development of the blow molding machine manufacturing machinery industry. The film made by a hair dryer can be widely used for light and heavy packaging due to its good barrier properties, freshness, moisture resistance, frost resistance, oxygen resistance, and oil resistance. Such as various fresh fruits, meat products, Pickled vegetables, fresh milk, liquid drinks, medical supplies and other fields are widely used.

In order to facilitate the lifting and normal blowing of the film by the film blowing machine, the temperature of the film blowing machine needs an optimal temperature. How will this temperature be controlled. When cleaning the film mouth and changing the mesh, protective gloves should be worn, and attention should be paid to the exposed parts of the wiring terminals at the machine head to avoid electric shock injuries; When cleaning the film port and changing the screen, a copper shovel must be used to avoid damaging the film port and changing the screen. At the same time, when stopping the machine to change the screen, attention should be paid to improving efficiency, timing, and temperature should not be lowered to avoid affecting the next film blowing work.
