The control of the temperature of the plastic film blowing machine is helpful for better film blowing, and the film can reach the expected quality. But how to control the temperature of plastic film blowing machine for better blown film, let me understand the role of temperature on blown film.
The film made by the plastic film blowing machine is widely used in light and heavy packaging due to its good barrier properties, freshness, moisture resistance, frost resistance, oxygen barrier, and oil resistance. Such as a variety of fresh fruits, meat food, pickles, fresh milk, liquid drinks, medical supplies and other fields are commonly used. In order to facilitate the film blowing and normal film blowing, the temperature of the film blowing machine needs an optimal temperature, and how will this temperature be controlled.
According to the melting theory of plastics, the extruder screw of the blown film is divided into three sections: the feeding section, the melting section, and the homogenizing section. At the end of the feeding section and at the beginning of the melting section, according to the melting theory, its temperature should be the viscous flow temperature. The viscous flow temperatures of various blown film resins are PP: 164-175 degrees Celsius, PE: 105-135 degrees Celsius, and PA: 195-210 degrees Celsius. Environmental resolution production quality.
