Coiling of plastic-weaved cloth (PP、PE) →Coiling up in bracket ---Printing in obverse and reverse side with four to six color---Cutting (equipping computer to treat )—Bag tube turning--- Rectifying and checking--- forward position orientation---Spreading glue--- Stoving--- Opening bottom---Bag bottom adjusting--- Pasting mouth of valve--- Forming--- Sticking attached bottom --- Folding in reverse side to press--- Producing bag and stacking up.

The bag-making procedure is accomplished continually in one time, and the shape of the bag is valve mouth and square bottom。The whole product line assembles the control of machine, electricity and steam
