A flat bag having side gussets and a simple bottom seam is made first. The side gussets are subsequently spread to transform the bottom portion of the bag into a block bottom in such a manner that the underside of the bag and the lower folded edge are retained in a portion which extends from the bottom seam by a distance equal to the gusset depth. The upper folded edge and/or the upper side of the bag is gripped by movable gripping means, and the gripping means are moved relative to the support so as to form the block bottom. The gripping means which grip the upper folded edge and/or the upper side of the bag are moved tangentially to the support for the bag during the transformation of the bottom portion whereas a lifting component of motion is avoided.
LPP Block Bottom Bag is mainly used by Cement Plants all over the world due to its specialty of valve, flat bottom and filling system with the Micro/nano Perforation as per the requirements
