Abstract

The production of the base of a bag uses continuous strip with a folded edge consisting of two layers of heat-sealing thermoplastic film. The folded edge is folded again inwards to form two equal sections of double thickness, these are parted by a triangular tool, each section is pressed on a side of the triangle and part is cut off, the cut edges being then welded together to form a base. The process produces a square base.
