Abstract: A roll of separable bags which leaves no scrap material and method of making a roll of separable bags which leaves no scrap material is disclosed herein. An elongated tube of material having a length and a width is laid flat, forming a web of material. The web of material comprises an outer and an inner sheet portion. First and second seals are formed widthwise across the outer and inner sheet portions. First and second bag separating perforation lines are formed widthwise across the outer and inner sheet portions. A user may tear one bag away from the roll of bags by using the bag separating perforation line. The user may then deploy the handles of the bag by tearing along the handle perforation lines.

Abstract: An apparatus for making a self-opening bag pack includes a supply of flexible film material. An extruder forms a continuous tube of film. A flattener flattens the tube. A first sealer forms a bottom seal across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks has a bag mouth at a predetermined distance from the bottom seal. Second and third sealers form angled seals at lower corners of the bag blank forming a flat bottomed bag. An adhesion knife penetrates the bag pack adhering adjacent bag blanks together in the bag pack. An aperture maker forms apertures 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 is adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack

Abstract: A method of manufacturing a roll of bags includes: moving a layflat tubing from a feed end toward a produce end of a workstation; sealing the layflat tubing to form sealing lines along a width direction of the layflat tubing; punching the layflat tubing to form punching lines along the width direction; spraying, by a coding machine coupled to the workstation, at least one counting mark on the layflat tubing; cutting by the workstation, the layflat tubing along the width direction to form connected bags; and winding the connected bags into the roll of bags. The connected bags are separated by the punching lines, each bag has one of the sealing lines, and at least one bag has the at least one sprayed counting mark that counts its relative position in the roll of bags.

Abstract: A system and method of at least partially forming reinforced packages. The method comprises moving a web of material in a downstream direction through a web forming section, at least partially forming at least a bag portion in the web of material during the moving the web of material through the web forming section, forming an attached web by adhering a construct to the bag portion of the web of material, and moving the attached web through a separating station. The moving the attached web can comprise moving the construct with the web of material. The method further can comprise separating the bag portion from a remainder of the web of material to form a bag during the moving the attached web through the separating station, the bag being attached to the construct.

Abstract: Bags are made, with which a stack is formed. To do this, a tube is formed with a strip of flexible material, a portion of tube is separated at the front of the tube forming a first flap at the rear of the portion of tube, the first flap prolonging the first wall of the portion beyond the end of the second wall adjacent to the first wall, a bag is formed with each portion of tube, and a stack of bags is formed, the first wall of the first of the bags being against the second wall of the adjacent second bag. An anti-adhesive coating is applied on to the first wall of the first bag and a coat of adhesive is applied on to the second wall of the second bag ensuring the temporary attachment with the anti-adhesive coating.

Abstract: A gusset preheating assembly and a method of using the same. The assembly includes a heating gun assembly mounted on a frame. Spreader rods open up a gap in a bag's gusset and nozzles blow warmed air into the gap. Orthogonally arranged first and second hydraulic members are operatively engaged with heating gun assembly and are activated to move the heating gun assembly vertically or horizontally. Hot air blowing into the gap from the nozzle relaxes the gusset. Pressure is applied to the relaxed gusset, thereby reducing the thickness of the gusset region of the bag. The reduction in thickness makes it possible to increase the number of gusseted bags that are packaged in a container or on a roll.
