Haul-off unit is oscillating reverse by horizontal±180。.Its structure is reasonable, so it
economizes lots of energy and it is easy to maintain. By means of the reversing haul-off
unit, films can be produced without requiting rotating die head, so the structure of die head
is simplified. Reversing haul-off unit eliminates many problems of ling channel for the
rotating die head, difficult sealing for the melt, compound leakage being easy,
unsymmetrical heating, difficult maintenance, macro film tolerance and so on Haul-off
unit reduces the degree of difficulty for recipe of the multi-layer co-extruded product and
production technical processing control, if the blowing film line is with IBC (Internal Bubble
cooling system),it can produce film with the quality of more high-grade transparency and
better all round performance. The produced film is very flat, reel is high-quality by the use
of reversing haul-off units. The film can meet the demand for the high-speed printing.
