Blowing film is actually a kind of film between two-axis directional film and tape casting film. It can also be used to produce biaxial directional film by blowing method. As long as the temperature is appropriate, the ratio of blowing to traction is appropriate, the degree of orientation of biaxial direction can be approximately the same.
1. Two layers polypropylene film blowing machine,This machine set adopt bottom blow type to produce polypropylene plastic film with good fransparency and without such phenomena as flow liner,corrugation and fold,etc.
2.This screw material cylinder is elabroately made of 38CRMOALA alloy steel after nitrogen treatment and has best rigidity and corosion resistance.
3.The nould head is plated with hard chromium and has screw mandrel structrue with uniform and smooth material discharging.And the aircooled device has labyrinth type stucture with characteristica as uniform air-jut quantity,automatic temperature control and automatic heating.
4.The coiling device adopts torque motor to keep proper tension with even rolling and convenient roll replacing.
Tip of Blowing Film Technology: Blowing film is actually a kind of film between two-axis directional film and tape casting film. It can also be used to produce biaxial directional film by blowing method. As long as the temperature is appropriate, the ratio of blowing to traction is appropriate, the degree of orientation of biaxial direction can be approximately the same. When blown film is produced, if the traction speed is too fast and the ratio of blown film to blown film is too large, the difference between the longitudinal orientation and the transverse orientation may be too large. As a result, the transverse strength is low and the transverse orientation is easy to break, just like the one-way stretching process. The prevention method is to reduce the traction speed appropriately and make it match with the blowing ratio; increase the air circulation to make the blown film cool quickly and avoid being stretched and oriented in the high elastic state at high temperature.
