Abstract: An apparatus for producing various shapes of polyethylene bags includes a heating mold separating means, a cutting mold separating means and a collecting means. By using such an apparatus for making PE bags, a double-layered polyethylene sheet rolled on a roller is transported into the heating mold separating means by input rollers to form polyethylene bags of any desired shape. Since the bags can not be completely separated from the sheets by heating mold, the bags together with the sheets must be sent into the cutting mold separating means by transporting rollers again. The cutting mold separating means will cut the boundary of the bag except the root portion, so that the bag is completely separated from the sheets, except for the root portion. Finally, the bags together with the sheets are sent into the collecting means. The cutter of the collecting means indents the root portion of the bags and the needles of the collecting means pokes through the root portion of the bags.
