PE Two-Color Mulch Film Blowing Machine

Product Description:

Features of mulch film blowing machine:
mulch film series blowing lines are developed by importing Japanese technology and combining with the situation of our country. It is mainly used to produce double colors plastics mulch and agricultural film, such as white and black (or silvery white) film. It resolved successfully many difficult problems for some machines such as easy mix materials, indistinct in color limits, not even in thickness, easy tearing in joint places, etc. It can also be used to produce the double layers film by changing the die partially.
The line has been improved for many times, and it has many merits now, such as the reasonable design, compact structure, convenient operation, especially the main motor has been changed into frequency conversion and after re-equipping the line, the efficiency of the line is increased and the energy consumption is reduced, the whole line function is more advanced and reasonable. And we can also carry full frequency conversion timing and other special equipping according to the consumers requirements.
