Procession Technology                                                           

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.      using blowing temperature for reference
