Procession Equipment                                                           

 common film blowing machine equipments available

using film extruder rotation screw of L/D  ratio ≥30 : 1(diameter 45mm) , which will help the finished film to achieve best film quality

Procession Technology                                                           

A  .     the preferred blow-up ratio is 1:2.5, the height from die of orifice to the nip roll should be higher than 2.5m which to insure full cooling and prevent film blocking.

B.   using blowing temperature for reference

c      the screw rotation should be slow at first ,and then adjust the screw rotation faster to match the request.
