Description
Technical field
The utility model is to belong to packaging field, especially a kind of sealing packaging bag.
Background technology
Sealing packaging bag is bonded, then sealed by sealing machine, multilayer according to specification difference using the material of different layers
Material can guarantee load-bearing and the leakproofness of sack, but existing sealing packaging bag is sealed when such as there is 3 layers or more of material
When need to fold, the thickness of the packaging bag after folding increases 1 times, it may appear that folds and irregular sealing line is caused the local flaw occur
Defect influences leakproofness and the aesthetics of product, in addition, sealing packaging bag, draws baling line by needle and penetrates packaging bag and sealed
Mouthful, too thick material makes the needle of sealing machine wear faster and is easy broken needle, and frequent needle exchange causes processing cost higher, efficiency low
Under.
Invention content
In view of the deficiencies of the prior art, the technical solution of the utility model, solve sealing packaging bag in load-bearing property and
Contradiction in sealing performance reaches novel durable function with simple and clear design, and sealing packaging bag is by following technology
What scheme was realized.
A kind of sealing packaging bag, including bag body, the bag body are made of multiple material layers, and the multiple material layer includes the
One material layer, second material layer, third material layer, the first material layer are to be located at bag positioned at bag volume surrounding, second material layer
Body middle layer, third material layer are located at the internal layer of bag, which is characterized in that the second material layer of bag body sack position is shorter than the first material
The bed of material and third material layer.
Preferably, in bag body sack position, after first material layer and third material layer are along second material layer edge fold
Form sealing area.
The sealing area is used to carry out sealing by sewing machine, the line of sealing run through first material layer, second material layer and
Third material layer.
Preferably, the first material layer and third material layer are longer than second material layer.
Preferably, the material of the material layer includes：Brown paper, plastic paper, non-woven fabrics, plastic foil.
Preferably, identical or different material can be used in the material layer.
Preferably, the second material layer is made of single-layer or multi-layer material layer, and material layer is by brown paper, plastic paper, nothing
The one or more compositions of woven fabric, plastic foil.
The utility model has the beneficial effects that：It by utility model sealing packaging bag, solves packaging bag in sealing, rolls over
The problem of laminate materials layer is too thick, seam line unobvious out-of-flatness, sewing machine eedle is easily broken off.The utility model is simple in structure,
Keep packaging bag sealing more simple and efficient, improves industrial production efficiency.
Description of the drawings
Fig. 1 is the sealing package construction schematic diagram of the utility model specific embodiment.
Fig. 2 is the positive structure schematic of sealing packaging bag.
Fig. 3 is the side sectional view of sealing packaging bag.
In figure：1-bag body, 2-first material layers, 3-second material layers, 4-third material layers, 5-sealing areas, 6-
Seam line.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1 to Figure 3, a kind of sealing packaging bag, including bag body 1, the bag body 1 are made of multiple material layers, institute
It includes first material layer 2, second material layer 3, third material layer 4 to state multiple material layers, and the first material layer 2 is to be located at bag body
Outer layer, second material layer 3 are located at 1 middle layer of bag body, third material layer 4 is located at 1 internal layer of bag body, and the second of 1 sack position of bag body
Material layer 3 is shorter than first material layer 2 and third material layer 4.
In 1 sack position of bag body, second material layer 3, the second material are also set up between first material layer 2 and third material layer 4
The presence of the bed of material 3 so that packaging bag load-bearing property is strengthened, while keeping 6 position of seam line clear, 2 He of first material layer
Third material layer 4 is along sealing area 5 is formed after 3 edge fold of second material layer, sealing area 5 by sewing machine for being stitched
Mouthful, seam line 6 runs through first material layer 2, second material layer 3 and third material layer 4.
The third material layer 4 is longer than second material layer 3.Third material layer 4 is longer than second material layer 3, can to wrap
Pack opens third material layer 4 easily when loading product, will not make product is wrongly installed to enter other materials layer.
The material of the material layer includes：Brown paper, plastic paper, non-woven fabrics, plastic foil.
Identical or different material can be used in the material layer.
3 aperture position of the second material layer is 6 position of packaging bag seam line.When second material layer 3 is not involved in sealing
The folding of material, reduces sealing region folded portion thickness, and aperture position can make packaging bag seam line 6 clear smooth.
The second material layer 3 is made of one or two layers material layer.Packet can be greatly improved in the construction of two layers of material
The load-bearing property of pack.
The preferred embodiment that these are only the utility model, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
