2000mm Three-layer/Five-layer Co-extruded High-speed Cast PE Stretch Film Line

This line is designed for producing single/double-side self-adhesive three-layer/five-layer
co-extruded stretch film by extruder with LLDPE and several kinds of resins.

Features of Machine 
1. Adopt the latest winding system to cut the film instantly and change the rolls quickly, greatly reducing the waste at changing rolls and saving cost.
2. Adopt adjustable parting system with separate rollers, adjustable paring gap, with excellent effect.
3. Equipped with weightless automatic dosing and mixing system to control the accuracy of the formula and save the labor cost.
4.The die for this line is optional with edge cover system to reduce the necking of film and ensure the stable production of film in high speed. This system can guarantee the stability of melt film edge, though the raw material and thickness of product are changed frequently. The background reason is that a modern production line must meet customers’ various requirements, like a smaller product order that need change the production technics and formula constantly. If without this system, the melt film edge will not be stable. This system always puts the same raw material (such as LLDPE) into edge of melt film and makes the edge melt at the same production environment all the time.
5. The cooling roller adopts major diameter and special flow to ensure good cooling and molding under high speed production.
6. Adopt professional screw design and gem treatment device to ensure sufficient plasticization and stable extrusion. The barrel adopts air-cooling heating device with good heat transfer, heat release and low noise. Robot operation, fully automatic paper core loading, finished roll changing and unloading system to ensure stable production under high capacity and high speed.
7. The whole line adopts PLC and touch screen with human-machine interface and supports long-distance detection by network which can offer all-round system maintenance, shorten the distance of space-time and realize commissioning in different places. 
8. All the electric control parts are famous brands to ensure machine’s quality and reliable running.

Characteristics of Product
1.High tensile strength, puncture resistance and impact strength. 
2.Good shrinking memory and self-adhesion can make goods integrity to prevent goods from loosening and collapsing during transportation and being polluted by dust. 
3.Good transparency and extensibility can make the package beautiful, economical and practical.

Main Applications of Product
The film can be widely used in wrapping of palletized goods. It’s a good substitute for hot shrink packaging film.
