1. O the manufacture method of type air-isolated and self-adhering packing bag, it is characterized in that, this packaging bag is made up of four layers of resin film, part heat-sealing through a series of heat-sealing equipment forms the space that can deposit medium air, four layers of resin film comprise the ground floor resin film, the resin film and the second layer resin film of two broads of the 4th layer of resin film, two narrower resin films of three-layer resin film, wherein second layer resin film inner surface part has high temperature resistant antiseized printing baffling device, and the inner surface of second layer resin film is local when printing needs through sided corona treatment, make the heat-sealing that forms a falseness between second layer resin film and the three-layer resin film in the time of must be able to being implemented in simultaneously heat-sealing, be unlikely to make second layer resin film and three-layer resin film to bond together;

  • Ground floor resin film and the 4th layer of resin film are placed on top layer up and down respectively, second layer resin film and three-layer resin film are placed on the intermediate layer, after overlapping the putting well through first the heat-sealing, second the heat-sealing heat-sealing and many articles the 3rd the heat-sealing heat-sealings, through the heat-sealing of the 4th heat-sealing, the 5th heat-sealing, first fold line, second fold line, the 3rd fold line, the 4th fold line, the 5th fold line and the 6th heat-sealing, then form the space that to deposit medium air again;

    A plurality of spaces link to each other and inflate the three-dimensional air packaging material of back formation;

    Described three-dimensional air packaging material, through the first interrupted fold line, second fold line, the 3rd fold line, the 4th fold line, after five fold line folded configuration of the 5th fold line, carry out local heat-sealing, after air puts on rations that house steward is unified and enters and enter the space that can deposit medium air through the over-allocation passage, utilize the viscosity characteristics of film self and the principle of air pressure, medium air can not therefrom be leaked out, and utilize second layer resin film inner surface part to have the printing baffling device, making the first base part that seals and the 5th heat-sealing is the technology that hollow pseudo-heat seals at the position of printing the common formation of heat-sealing on the baffling device;

    Air enters through house steward'"'"'s the opening of putting on rations and through the over-allocation passage, enters each space smoothly during inflation, has just formed the air packaging material of a solid, is O type air-isolated and self-adhering packing bag.
