Double Winder Multilayer Blown Film Extrusion with Rotary Die Head
Characteristics:
1.Die head is layer type spiral mandrel, continuous 3600 rotation.
2.Screen pack changer design is reliable, safe in operation and change the fitter screen easier
3.Double winder used for cutting film into two rolls in one time
4.Various functional parts may be installed to the lies.,such as length counting device, vertical
cutting device, cooling water row pipe, film spreading roller, scrap collecting device.
Use:
The lines are designed developed by our corporation according to market need. they reach the advanced levels in the 90s.come up with analogous lines in home.
It is optimum designed on the trounds of preference of analogous line in foreign and home.
The lines can be blown continous 800 - 1500mm in folding width 0.08mm in the chickness packaging films,film has good insulation ,for instance holding temperature, anti - humid, anti-breeze, anti-rain ,anti-rost, insulation oxygen, oil resistive, and so used for light and heavey duty packaging, for example fresh fruits, meat feeding, salt vegetables, fresh milk, drink.
