2.ZQ-CRM1800 three-layer coextrusion stretch film extrusion line.
3.Film width:1500mm.

                                ZQ-CRM1800 three-layer coextrusion stretch film extrusion line

   This machine uses LLDPE as main raw material,and adopts several different kinds of resin.It can produce two-layer or three-layer stretch film which has the property of autohension.The coextrusion stretch film has better tensile strength, anti puncture capability and shock resistance than monolayer film.And in the meantime,it has good retraction memory and autohension.It also has excellent transparency and extensibility.

Machine features:

1.Special designed screw and static mixer,to insure fine plastifying, uniform colour and lustre and high capacity.

2.The material of die head adopts imported die steel,and processes with finish machining,so it can avoid the deformation of die head.

3.The inside of cooling steel roll adopts bidirection return circuit design, inlaying spiral passageway,it can ensure the uniform temperature of the roll surface.

4.This production line adopts PLC control, automatic changing reel and conceal automatic cutter,it is safe and convenient.
