Abstract
The utility model discloses a heat seal paper bag with hot melt adhesive of a super-large area. The heat seal paper bag with the hot melt adhesive of the super-large area comprises a hot melting glue layer, a bag mouth portion and paper. The hot melting glue layer is arranged between the bag mouth portion and the paper, and the hot melting glue layer is in a sawtooth shape. The heat seal paper bag with the hot melt adhesive of the super-large area enables hot melting glue to melt quickly when the hot melting glue layer is heated, and can go on to a next bonding process fast, and therefore integral filling speed is improved, and labor producing efficiency is greatly improved.
Description
Technical field
The utility model relates to packaging bag field, particularly a kind of hot-seal paper bag with overlarge area hot melt adhesive.
Background technology
At present when using hot-seal paper bag, common operating sequence is as shown in Figure 1, after material is packed into the bag 4 of paper bag by the opening part from sack oral area 2, and the hot melt adhesive water layer 1 of heating oral area, after the hot melt glue melting layer, bending 180 degree are also bonding from back to front along oral area bending line 3; In this process, the automatic packaging machine device all adopts high temperature air to heat the hot melt adhesive water layer 1 of oral area, because hot air heating hot melt adhesive water layer needs the regular hour, thereby affected filling bags bulk velocity on conveyor line, the time that how to shorten heat hot melten gel water layer has become a difficult problem.
Two-layer paper is rolled into tubular, the two ends of outer paper are bonding at outer paper adhesive portion 6 use glue, the two ends of internal layer paper are bonding at internal layer paper adhesive portion 5 use glue, each layer paper of sack oral area 2 from back to front successively one deck form stepped than a floor height, and the position blade coating hot melt glue of the hot melt adhesive water layer 1 of oral area, the two-layer paper of hot melt glue blade coating exceeding on the position at the rear portion.Blade coating technique due to what adopt, as shown in Figure 3, hot melt adhesive water layer 1 by blade coating equably on paper 9, hot melt adhesive water layer surface 11 forms smooth mirror-like, this shape is a kind of shape of body surface area minimum, when hot air blows on this surface, hot melt glue is heated when preparing heat seal, because heating surface area is little, so need the more time heat hot melt glue.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of hot-seal paper bag with overlarge area hot melt adhesive, it makes when heat hot melten gel water layer, hot melt glue can melt rapidly, can enter very soon next bonding process, thereby improved whole filling speed, greatly improved labor efficiency.
For solveing the technical problem, the utility model provides a kind of hot-seal paper bag with overlarge area hot melt adhesive, hot-seal paper bag with overlarge area hot melt adhesive comprises hot melt adhesive water layer, sack oral area, paper, the hot melt adhesive water layer is between sack oral area and paper, it is characterized in that, the hot melt adhesive water layer be shaped as zigzag fashion.
Preferably, described hot-seal paper bag with overlarge area hot melt adhesive also comprises bottom oral area bending line, bag, bottom bending line, sack, the oral area bending line is positioned at the below of sack oral area, the bottom bending line is positioned at the top of sack bottom, and bag is between oral area bending line and bottom bending line.
Preferably, described hot-seal paper bag with overlarge area hot melt adhesive also comprises internal layer paper adhesive portion and outer paper adhesive portion, and internal layer paper adhesive portion extends to from the sack oral area bottom sack, and the outer paper adhesive portion extends to bottom sack from the oral area bending line.
Positive progressive effect of the present utility model is: the utility model makes the time of heating hot melt glue short, has also greatly improved entire package speed when having saved the energy, has been fit to the needs of large-scale industrial production.

The specific embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
as shown in Figure 4 and Figure 5, the hot-seal paper bag that the utlity model has the overlarge area hot melt adhesive comprises hot melt adhesive water layer 21, sack oral area 2, oral area bending line 3, bag 4, internal layer paper adhesive portion 5, outer paper adhesive portion 6, bottom bending line 7, sack bottom 8, paper 29, hot melt adhesive water layer 21 is between sack oral area 2 and paper 29, hot melt adhesive water layer 21 be shaped as zigzag fashion, oral area bending line 3 is positioned at the below of sack oral area 2, bottom bending line 7 is positioned at the top of sack bottom 8, bag 4 is between oral area bending line 3 and bottom bending line 7, internal layer paper adhesive portion 5 extends to sack bottom 8 from sack oral area 2, outer paper adhesive portion 6 extends to sack bottom 8 from oral area bending line 3.
when making hot-seal paper bag, change the technique of original blade coating hot melt adhesive water layer, roll out saw tooth shaped structure as shown in Figure 5 at the position of the hot melt adhesive water layer of oral area with oblique gear, at this time, the gross area on the hot melt adhesive water layer surface in the gross area comparison diagram 3 on hot melt adhesive water layer surface 22 has just enlarged 3 ~ 4 times, when hot air is blowing this when surface, on the one hand, because heating surface area is large 3 ~ 4 times, the flash time of the glue of same grammes per square metre has just shortened 3 ~ 4 times, on the other hand, when air is blowing this rough surface long time of meeting stop, total like this time of heat is just shorter, thereby greatly shortened total time of heat, improved total package speed, saved simultaneously the energy.
Two-layer paper is rolled into tubular, and wherein the two ends of outer paper are bonding firmly at outer paper bonding position 6 use glue, and the two ends of internal layer paper are bonding firm at internal layer paper adhesive portion 5 use glue.Can find out at sack oral area 2, each layer paper from back to front successively one deck form stepped than a floor height, grow layer by layer 2 ~ 3 centimetres, the hot melt adhesive water layer 21 of oral area with regard to roll extrusion on the paper that grows at rear portion, the structure of sack bottom 8 is opposite with the symmetrical configuration of sack oral area 2, sack bottom before dispatching from the factory just along sack bottom bending line 7 backward bending 180 spend, and it is firm to add heat bonding.
After material is packed into bag 4 from the position that sack oral area 2 opens, sack is moved to heating station by automatic equipment, when hot air blows on hot melt adhesive water layer 21 at oral area, just because of this saw tooth shaped structure as hot melt adhesive water layer surface 22 in Fig. 5 figure, greatly increased the total surface area of glue, the increase of heating surface area makes hot melt glue melt rapidly, sack just can move to rapidly next bonding workstation, so just greatly improved work efficiency, simultaneously also save the energy, be fit to the needs of large-scale industrial production.
Although more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these are only casehistorys, under the prerequisite that does not deviate from principle of the present utility model and essence, can make various changes or modifications to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
