      PE shrinking film:

      It is economical and applicable packaging materials. With excellent elongation, anti-piercing and excellent binding force, it is suitable for stacking of various articles and packaging of pallets.

      It is made with 3 layers and 5 layers co-extrusion casting film equipment, and there are many specifications for choice of the client.

      Manual shrinking film: Applicable for simple manual operation.

      Shrinking film for use of machine: Suitable for traditional shrinking film twisting machine, or mechanical pre-stretching machine, and its elongation ratio is 2 times as much (+100%).

      Pre-stretching shrinking film: suitable for power-driven pre-stretching shrinking film twisting machine, and its elongation ratio is 3 times as much (+200%).

      Material: linear low density (LLDPE)

      Size: thickness: 0.012-0.040mm, Width: 300~3,000mm, length: 200~4,000M

      Diameter of tube: I.D. 2” and 3”, bonding face: internal bonding/external bonding/ double-face bonding
