Abstract
An apparatus for making a self-opening bag pack includes a supply of film material. An extruder forms a continuous tube of film. A flattener flattens the tube. A corona treater treats at least one surface of the flattened tube. A first sealer forms a bottom seam across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks at a predetermined distance from the bottom seam. A stacker forms the bag blanks into a bag pack. An adhesion knife penetrates the bag pack and adheres adjacent bag blanks together in the bag pack. An aperture maker forms means for suspending the bag pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag will be adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.
