 ProcessionEquipment                                                          

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

ProcessionTechnology                                                           

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

b.      fleshly blown film product feels a little brittle and crisp ,due to dehydration in production ,after 24 hours ,its function regains to normal plastics .

c.       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.

d.      using blowing temperature for reference
