This unit mainly applies LLDPE and adopts several kinds of resins to manufacture single/double-side self-adhesive three-layer stretch wrapping film by extruder. The multi-layer co-extruded stretch film has better tensile strength, puncture resistance and impact resistance  than simple-layer or two-layer stretch wrapping film. Its good shrinking memory and self-adhesive function can make goods integrity to prevent them from loosening and collapsing transportation and being polluted by dust. The transparency and tensile strength of this product can make the packaging beautiful, economical and practical. The film can be widely used for wrapping of palletized goods. It’s good substitute for hot shrink packaging film in transportation.
