Features of Double Layer Co-extrusion Stretch Film Machine
1. With LLDPE as its main raw material and different grades of resin, the double layer co-extrusion stretch film machine produces a single-sided or double-sided self-adhesive stretch film through extruder. The stretch film thus produced has strong tensility, puncture and impact resistance.
2. Made of 38CRNOALA alloy steel and with nitrogen treatment and precision processing, the screw has proper hardness and is durable.
3. Temperature is controlled by fully automatic controlling system. And the multi-point adjustment of the T mould produce film with uniform thickness.
4. The circulating water cooling system has good cooling effects.
5. The winder is controlled by PLC system and adopts automatic roll change. Besides, the cutting device and dual winding structure of the winder renders neat and smooth film winding.
6. Stretch film has good memory of retraction and autohension. Goods can be tightly bound by the stretch film to prevent sudden collapse in transportation and dust pollution. Besides, the stretch film has high transparency and extensibility, creating beautiful and practical packaging. It is widely used for palletizing of bulk cargo as a desirable substitute of shrink packaging film during transportation.
