Two-Layer LLDPE Stretching Film Making Machine (SJ-65*2-1250)

Use: This machine set is used for producing LDPE or LLDPE stretch film, 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.
Characteristics:
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.
