  • Patent number: 9028386
    Abstract: The plastic bag may include flexible thermoplastic sidewalls that have a pattern imparted onto them. The wrinkle pattern may be a plurality of linear ribs formed into the sidewall that may be arranged adjacent and parallel to one another. To impart the pattern to the sidewall, a thermoplastic web used to make the sidewall may be directed between a first cylindrical roller and a second cylindrical roller, each of which may have a plurality of spaced ridges extending about their peripheries. When the web is directed between the first and second rollers, the meshing of the ridges may form ribs into the web.

    Abstract: A flexible film, and articles comprising the film, comprises interleaved pluralities of each of first bands and second bands disposed adjacent to the first bands. Both the first and second bands have a length and a width; the first bands comprise a first film basis weight and first and second regions. The first regions and second regions being comprised of the same material composition. The first regions undergo a substantially molecular-level deformation and the second regions initially undergo a substantially geometric deformation when the sheet material is subjected to an applied elongation along at least one axis. The second bands comprise a second film basis weight and a plurality of corrugations disposed along the length of the band. In this aspect the material may be described as having alternating bands of structural-elastic-like film and ring-rolled film.

  • Publication number: 20130011084
    Abstract: A flexible film, and articles comprising the film, comprises interleaved pluralities of each of first bands and second bands disposed adjacent to the first bands. Both the first and second bands have a length and a width; the first bands comprise a first film basis weight and first and second regions. The first regions and second regions being comprised of the same material composition. The first regions undergo a substantially molecular-level deformation and the second regions initially undergo a substantially geometric deformation when the sheet material is subjected to an applied elongation along at least one axis. The second bands comprise a second film basis weight and a plurality of corrugations disposed along the length of the band. In this aspect the material may be described as having alternating bands of structural-elastic-like film and ring-rolled film.

  • Patent number: 8317670
    Abstract: A trifold side seamed plastic produce bag includes a front wall and a taller back wall, first and second side edges sealed together and a seamless bag bottom. The taller back wall provides means for finding the bag opening. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method and apparatus for producing the bags includes a slitter that removes a strip of plastic from only the top layer of the bag stream to form an extended flap on each bag. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls.

  • Publication number: 20120270713
    Abstract: A machine for making bags is disclosed and includes input, drum, and output sections. The drum section has at least one seal bar on a drum. The sections are mounted to side frames that are single metal plates. The frames are not coated after being formed and/or are comprised of at least one of galvanized steel, galvannealed steel, stainless steel or aluminum. The drum is comprised of first and second plates, and opposing third and fourth plates. The first plate is rotatable with respect to the second plate, and the third plate is rotatable with respect to the fourth plate. The distance from the seal bars to the center of the drum is responsive to the rotation of the plates. The first plate has a plurality of non-radial grooves, and the second plate has a plurality of radial slots, with fixtures in the slots and grooves. The fixtures are connected to seal bars. The non-radial grooves are curved and/or spiraled. The plates are comprised of zinc plated steel and/or are discs.

  • Publication number: 20120231940
    Abstract: An air cushion manufacturing machine includes a film supply unit and a feed unit installed on a machine body and a sealing device for heat sealing an inflated double-layer film when the feed of the film stops. The manufacturing machine is characterized in that a solid state relay (SSR) is coupled to a power supply required by a heat sealer of the sealing device, and the solid state relay controlled by the processor compensates the heat loss of sealing according to the cycle of the sealing process, and a power-on time percentage is controlled to produce a punctuate periodic micro heating to the heat sealer and achieve a constant-temperature heat compensation for each sealing course of the heat sealer. The manufacturing machine is not affected by ambient temperature and is capable of improving the sealing effectiveness and overcome the drawback of conventional sealing devices that easily breaking an electrothermal wire.
