Feature:
Haul-off unit is oscillating reversed by horizontal ±180°. Its structure is reasonable, so it saves lots of energy and it is easy to maintain. By means of the reversing haul-off unit, films can be produced without requiring rotary die head, so the structure of die head is simplified. Reversing haul-off unit eliminates many problems of ling channel for the rotary 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 coextruded product and production technical processing control, if the blown film line is with IBC (Internal Bubble Cooling system), it can produce film with the quality of higher grade transparency and better all round performance. The produced film is very flat, reel is high-quality by these of reversing haul-off units. The film can meet the demand for the high-speed printing.
