Abstract
The utility model discloses a thermal packaging bag. A bag body of the thermal packaging bag comprises a thermal sealing edge which is directly and thermally packaged by at least two laminated substrates in pairs. The thermal packaging bag is characterized in that at most one surface of two surfaces where the thermal sealing edge is positioned is a plastic film layer. Compared with the prior art, the thermal packaging bag has the advantages that the thermal packaging bag contains two surfaces of the thermal sealing edge; at most one surface is the plastic film layer; therefore, the thermal packaging bag of the utility model has lower cost of material compared with the thermal packaging bag with plastic films at two sealing surfaces; furthermore, the bags can be made by thermal packaging, therefore, the thermal packaging bag of the utility model has simpler fabrication process compared with the paper bag with two surfaces bonded by viscous matters.
Description
Technical field
The utility model relates to packing, especially relates to a kind of heat sealing packaging bag.
Background technology
The side seal limit and the underseal limit of existing paper bag have two kinds, and a kind of is that two sealing surface surfaces all are paper, adopt stickum bonding, another kind is that two sealing surface surfaces all are plastic sheetings, adopt heat sealing, simpler, convenient than adopting the bonding manufacture craft of stickum, but material cost is than higher.
Summary of the invention
Technical problem to be solved in the utility model is the defective that remedies above-mentioned prior art, proposes a kind of heat sealing packaging bag.
Technical matters of the present utility model is solved like this:
This heat sealing packaging bag, bag comprise the heat-sealing limit by at least one pair of stacked base material direct heat involution.
The characteristics of this heat sealing packaging bag are:
The two sides at place, described heat-sealing limit, having only one side at the most is plastic film layers.
Technical matters of the present utility model is further to solve like this:
The two sides at place, described heat-sealing limit, one side is a paper, another side is the paper that scribbles hot melt adhesive layer in advance.
The two sides at place, described heat-sealing limit all is the paper that scribbles hot melt adhesive layer in advance.
The two sides at place, described heat-sealing limit, one side is a paper, another side is the plastic sheeting face that is compounded on the paper.
The two sides at place, described heat-sealing limit, one side is a paper, another side is the plastic sheeting face of leaching membrane paper.
Described plastic sheeting face comprises polyethylene, polypropylene film face.
The beneficial effect of the utility model contrast prior art is:
The two sides at the place, heat-sealing limit of this heat sealing packaging bag, have only one side to contain plastic film layers at the most, than two sealing surface surfaces all is that the cost of material is low for the heat sealing packaging bag of plastic sheeting, can adopt the heat sealing bag again, all be that the paper bag manufacture craft of paper is simple than adopting the bonding two sides of stickum.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiment heat sealing of the utility model pill bag;
Fig. 2 is the cross-sectional view along the A-A line shown in Figure 1.
The specific embodiment
Heat sealing pill bag shown in the drawings has 40 gram/sq m leaching membrane papers, 2 heat sealings of polyethylene foil 3 to form by one 40 gram/square rice paper 1 and a single face.The unit price of 40 gram/square rice papers is half of 40 gram/sq m leaching membrane paper unit prices approximately, and the cost of material is low.
The two sides at heat-sealing place, limit simultaneously is a paper 1, another side is the polyethylene foil 3 of leaching membrane paper 2,3 of the polyethylene foils of the one side of paper 1 and leaching membrane paper 2 is relative, adopt simple, the effective heat sealing technology of production technology with the cooresponding side seal of pill bag limit 4 and underseal limit 5 involutions, be heat sealing pill bag.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
