Description
Technical field
The utility model is related to packaging bag field, more particularly to a kind of high-intensity packing bag.
Background technology
A piece of paper is generally taken in current packaging bag and a film is compound moreover, the intensity of this packaging bag is general, is easy
Rupture.And the back cover of packaging bag at present is all to use concordant back cover mode, as shown in Figure 1, both sides 10a, 10b of bottom are put down
It cuts, then concordantly encloses mucigel 20, then stick underseal paper 40 using glue 30 in outermost layer, the bottom of this packaging bag holds
It is easily rupturable.
Utility model content
The purpose of this utility model is that for the above-mentioned insufficient and defect of the prior art, a kind of high-intensity packing is provided
Bag, to solve the above problems.
Following technical scheme may be used to realize in the technical issues of the utility model is solved：
A kind of high-intensity packing bag includes the bag body made by extrusion coating paper, which is characterized in that the bag body from outside to inside according to
Secondary external paper layer, middle film layer, inner paper layer including mutually bonding, the outer paper on the two of the bag body bottom back cover side being oppositely arranged
Layer, middle film layer, inner paper layer length are ladder-like arranged, when bonding, wherein the external paper layer on a back cover side, middle film layer, interior paper
Layer is mutually bonded with the external paper layer, middle film layer, inner paper layer on other back cover side, and it is adjacent between layer staggeredly overlap and bond.
In a preferred embodiments of the utility model, lead between the external paper layer of the bag body, middle film layer, inner paper layer
The point glue bond of super-interval.
In a preferred embodiments of the utility model, the external paper layer and inner paper layer are stretchable paper, the intermediate coat
Layer is polyethylene film.
As a result of technical solution as above, a bag body is made using three layers of extrusion coating paper in the utility model, increases a bag body
Intensity, and utilize special back cover side adhesive means, considerably increase the utility model bottom resistance to fracture ability so that this
Utility model can hold 50kg contents, and content can be cement, lime or mortar etc..
Description of the drawings

The utility model is expanded on further in face.
Include the bag body 100 made by extrusion coating paper, bag body 100 referring to a kind of Fig. 2 to high-intensity packing bag shown in Fig. 4
Include external paper layer 110, middle film layer 120, the inner paper layer 130 mutually bonded successively from outside to inside.External paper layer in the present embodiment
110 and inner paper layer 130 be stretchable paper, middle film layer 120 be polyethylene film.The bag external paper layer 110 of body 100, middle film layer 120,
Bonded by the dispensing at interval 140 between inner paper layer 130, can not only pack adhesion strength, and save raw material, reduce at
This.
The external paper layer 161 on the two back cover sides 160,170 being oppositely arranged of bag body 100 bottom, 171, middle film layer 162,
172, inner paper layer 163,173 length are ladder-like arranged, when bonding, wherein external paper layer 161, the middle film layer on a back cover side 160
162, inner paper layer 163 and the external paper layer 171, middle film layer 172, inner paper layer 173 on other back cover side 170 mutually bond, and phase
Layer between neighbour staggeredly overlaps bonding by glue 150.
A bag body is made using three layers of extrusion coating paper in the utility model, increases the intensity of bag body, and utilize special back cover
Side adhesive means considerably increase the utility model bottom resistance to fracture ability so that the utility model can hold 50kg contents
Object, content can be cement, lime or mortar etc..Current packaging bag is fallen when equipped with 25KG contents from the position of 2m high
It will rupture three times, and the packaging bag of the utility model falls five times from the position of 2m high when equipped with 25KG contents and all will not
Rupture.
