Problems solved by technology
[0002] At present, when using heat-sealed paper bags, the usual operating procedures are as follows: figure 1 As shown, when the material is filled into the bag body 4 of the paper bag from the opening of the mouth 2 of the bag, the hot melt glue layer 1 at the mouth is heated, and after the hot melt glue layer melts, it is drawn along the bending line 3 at the mouth. Then bend forward 180 degrees and bond; in this process, the automatic packaging machine uses high-temperature air to heat the hot-melt glue layer 1 at the mouth, because it takes a certain amount of time for the hot air to heat the hot-melt glue layer, which affects the How to shorten the time for heating the hot melt glue layer has become a difficult problem for the overall speed of filling bags on the assembly line

The invention discloses a heat seal paper bag with ultra-large-area hot melt glue. The heat seal paper bag with the ultra-large-area hot melt glue comprises a hot melt glue layer, a bag opening and paper, wherein the hot melt glue layer is arranged between the bag opening and the paper and is serrated. When the hot melt glue layer is used, the hot melt glue can be rapidly melted and can rapidly enter a next bonding process, so that overall filling speed is increased, and labor productivity is greatly improved.
Description
technical field [0001] The invention relates to the field of packaging bags, in particular to a heat-sealed paper bag with a super large area of hot melt adhesive. Background technique [0002] At present, when using heat-sealed paper bags, the usual operating procedures are as follows: figure 1 As shown, when the material is filled into the bag body 4 of the paper bag from the opening of the mouth 2 of the bag, the hot melt glue layer 1 at the mouth is heated, and after the hot melt glue layer melts, it is drawn along the bending line 3 at the mouth. Then bend forward 180 degrees and bond; in this process, the automatic packaging machine uses high-temperature air to heat the hot-melt glue layer 1 at the mouth, because it takes a certain amount of time for the hot air to heat the hot-melt glue layer, which affects the How to shorten the time for heating the hot melt glue layer has become a difficult problem for the overall speed of filling bags on the assembly line.
