The haul off unit can swing horizontally at 180 degrees. With a reasonable structure, it is easy to maintain. By means of swinging of the haul off unit, films can be produced without die head rotation, so the structure of die head can be greatly simplified. This helps eliminate such problems as long channel for the rotating die head, difficult sealing for the melt, easy leakage, uneven heating, and large difference in film thickness. The use of haul off unit can also help simplify the recipe for multi-layer co-extruded film and reduce the difficulty of controlling production process.
If needed, our multi-layer film blowing machine can be equipped with an IBC (internal bubble cooling) system so as to produce films with higher transparency and better all around performance. With great flatness, the films made by our film blowing line can meet high speed, high precision printing demand.
