This machine has been awarded many patents: 99201634.7, 99247820.0.
This machine breaks the former shortcoming of only using expensive special coating plastics for film instead, it use common polypropylene power material plus a little polyethylene. Under the molten state, it has a peculiar gluey function to daub film between braiding bag and paper or braiding bag and BOPP film or on braiding film and make all kinds of compound braiding bags through pasting and cutting by pressure.
As a result, it greatly reduces the cost and win better market for compound bags. The extruder of this unit can control the melting temperature automatically. It uses no-class speed adjuster to adjust the thickness of melting film, two-side or one-side film, double-mold head and the width of coating. The timber, which can be adjusted crossly, has auto-cutting side, blowing side and the M-folding side. If the device is cut off, the whole structure will operate in the same step. Moreover, this machine can also adjust the length of cutting bags by using no-class speed adjuster changing gears.
