Coextrusion Geomembrane Film Blowing Machine (SJ-GS)

Coextrusion Geomembrane Film Blowing Machine(SJ-GS)Use: The agricultural film, geomembrane film blowing line is used for making three layer co-extrusion wide film like three-layer compound plastic shed film, functional film, impermeable geomembrane, etc. Out of LLDPE, LDPE, EVA, MPE and HDPE materials. It is composed of three extruders, columnar filter screen, three-layer compound die, twin-tuyere air ring, hauling machine, coiling machine, temperature and electrical control system, etc. Product Description1. 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. 2. This machine set is to satisfy the customer's requirements of high quality, high out put film blowing equipment. It adopts the extruder with force feeding function, precision type ceramic heater, precision type double vents air ring, horizontal type rotary traction system, IBC inner cooling system, fully automatic surface friction type double cut double winders, computer concentrate control system, advanced technique and equipments.
