Definitions

  • This invention relates to a method for fill packaging a liquid packing material and a fill packaging machine utilizing such a method, and more particularly to a fill packaging method and fill packaging machine capable of blocking intrusion of a liquid packing material into a lateral seal portion.
  • a packaging film having a laminated structure comprised of a uniaxially or biaxially oriented base film layer and a non-oriented sealant layer or a packaging film having a single layer structure of partly coating a heat-sensitive adhesive layer onto a base film layer is folded at a central part thereof so as to face the sealant layer or the heat-sensitive adhesive layer inward, and side edge portions of the folded films are overlapped with each other and fused by heating and pressing with a pair of vertical sealing rolls to form a longitudinally extended vertical seal portion while feeding downward, whereby the packaging film is shaped into a cylindrical form.
  • the cylindrically formed film is fed downward while being fused by heating and pressing with a plurality of heat sealing bars positioned at equal intervals in a circumferential direction on each periphery of a pair of lateral sealing rolls in a lateral sealing apparatus to intermittently form lateral sealed portions each extending a widthwise direction of the cylindrically formed packaging film at given intervals in the longitudinal direction of the packaging film, whereby package bags are manufactured.
  • a packing material is filled into each of the package bags by continuously feeding the packing material to the packaging film or intermittently feeding from the formation of one lateral sealed portion in the cylindrically formed packaging film to the formation of next lateral sealed portion, and thereafter the continuously manufactured package bags are cut at a middle part of the lateral sealed portion by a cutting mechanism and taken out in the form of a single bag or at a continuous state of plural bags.
  • Patent Document 1 JP-A-1104-114841
  • lateral sealing is performed by the heat sealing bars on the lateral sealing rolls while pushing out the packing material in the cylindrically formed packaging film, whereby the intrusion of the packing material into the lateral sealed portion is suppressed but is not sufficient.
  • the packing material contains granulates as used in dressing for example, there is a fear that the granulates cannot be pushed out by the heat sealing bars and may be intruded into the lateral sealed portion. If the granulates are intruded into the lateral sealed portion, not only the appearance is damaged but also bubbling is generated to cause poor sealing, and there is a fear of leaking the packing material.
  • the invention is to provide a method for fill packaging a liquid packing material capable of filling the liquid packing material without intruding bubbles, granulates or the like into a lateral sealed portion and improving the productivity, and a fill packaging machine utilizing such a method.
