1.Screw and cylinder are all
made of 38CRMOALA alloy and treates by nitrogen,It has an advantage of corrosion
resistance and endurance etc.
2.The cooling device adopts cycle water cooling provide the best transparent
effect of the stretch film.
3.Take-up equipment adopts with friction type rewinding and equipment with edge
correcting device to ensure the quality The machine set is used for producing
LDPE or LLDPE.stretch film, which is equipped with single screw, the extruded
stretchsides adhesive, If the machine adopts double screws, the two hoppers
should use different type of material, one side of the extruded stretch film is
adhesive and the other side is normal, It is widely used for packing
architecture and hardware parts etc.
