It is reported that bag making machine is applied to manufacturing and printing the uncolored vest bags made of HDPE, LDPE roll films and PE Stretch Wrap Films. It adopts PLC control, double servo motor fixed length and the liquid crystal touch screen actual display to finish the feeding, sealing, cutting, punching holes and transporting only in one process. It is of high degree of automation and good economic result. As a hand quilter I have gotten in the habit of carrying my cut pieces in a plastic bag. Threads also do well in plastic bags as the thread slides easily through the sealer part of the bag while holding the other spools of thread. However, the machine can also be employed if the tubular bags to be manufactured are to be of greater width than afore-mentioned and if sealing of the longitudinal joint is affected in a manner other than by an entrained internal seal strip, such as, for example, by overlapping strip edges.
