Temperature control of blown film machine

Reasonable and scientific temperature control of plastic film blowing machine is more conducive to better film blowing, and blown film can achieve the expected quality goals. But how to control the temperature of the plastic film blowing machine to blow the film better? Let me understand the effect of temperature on blown film.
The film made by plastic film blowing machine can be widely used for light and heavy packaging due to its good barrier properties, preservation, moisture resistance, frost resistance, oxygen barrier, 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 film lifting and normal film blowing of the blown film machine, the temperature of the blown film machine needs an optimal temperature. How will this temperature be controlled.
According to the theory of plastic melting, the extruder screw for blown film is divided into three sections: feeding section, melting section, and homogenization section. At the end of the feeding section and the beginning of the melting section, according to the melting theory, its temperature should be the viscous flow temperature. The viscosity flow temperatures of various blown film resins are PP: 164-175 degrees Celsius, PE: 105-135 degrees Celsius, PA: 195-210 degrees Celsius. The environment determines the quality of products.
