Abstract
The utility model discloses a kind of cube plastic packaging bag, bag body is straight plastic film tube, and one end of straight plastic film tube is openend, and the other end is blind end.The product is not easy to tear.Finished product is cut by blowing cylindrical material one-shot forming, then heat seal, and blanking is simple, convenient processing.
Description
Technical field
It the utility model is related to packaging bag, more particularly to a kind of square bottom plastic packaging bag for tobacco leaf packaging.
Background technology
The species of existing packaging bag is a lot, but most of plastic packaging bags are all through folding, and hot pressing, shear the one of aftershaping
Word bottom bag, but the packaging bag at this word bottom, when packing rectangle object, the inner surface of packaging bag can not be complete with packed article
Full fitting.And it is smaller that packaging bag struts rear accommodation space, can not accommodate more articles.
In addition, current cube plastic packaging bag, the seam of joint place is at an acute angle, is easily ftractureed from there during use.
Utility model content
To solve the problems, such as that above-mentioned cube plastic packaging bag joint place is easily torn in use, the utility model carries
For a kind of cube plastic packaging bag, the increase of packaging bag space, joint place is not easy to tear, and uses integral type, and blanking is simple, processing
It is convenient.
Realize that the technical scheme of above-mentioned purpose is as follows：
A kind of cube plastic packaging bag, bag body are straight plastic film tube, and one end of straight plastic film tube is openend, another
End is blind end, including front, the back side, left surface, right flank, among the back side longitudinal direction split for single piece of material when, front and
Back bottom is trapezoidal, and rectangle is connect under trapezoidal；The left surface, right flank bottom are trapezoidal, and rectangle is connect under trapezoidal；The left side
There is vertically folded line among face, right flank；Pass through the binding face of right flank two binding face with corresponding front and back respectively
Fitting, the binding face of left surface two are bonded with another binding face of corresponding front and back respectively, the bottom two of front and back
Individual horizontal abutment face is bonded to form blind end, obtains the finished product of plastic-film packing bag.
Joint place makes plastic bag packaging bag not easy to crack in 90 degree of intersections.And plastic packaging bag of the prior art, patch
Intersect out of plumb at conjunction, easily torn during use from infall.
Preferably, each joint place laminating type of cube plastic packaging bag is blanching treatment.
Preferably, the cube plastic packaging bag is water white transparency bag.
The advantages of cube polybag provided by the utility model, is：
1st, joint place makes plastic bag packaging bag not easy to crack in 90 degree of intersections.
2nd, by the foldover design of two sides, strutting packaging bag, trailing flank area is larger, and interior space is larger.Into
Product are cut by blowing cylindrical material one-shot forming, then heat seal, and blanking is simple, convenient processing.
3rd, the plastic packaging bag can be according to the plastics needed from unlike material different-thickness of packaged object, plastics
Packaging bag has the characteristics of intensity is high, and durability is good, good appearance, and size arbitrarily adjusts, and the plastic packaging bag is made
Type is succinct, and the transparent cleaning of color, processing and fabricating is simple, and cost is cheap, and application field is extensive.
Brief description of the drawings
Expanded view when Fig. 1 is longitudinally cutting among the back side of the utility model cube plastic packaging bag
Fig. 2 is the schematic perspective view of the utility model cube plastic packaging bag.
Fig. 3 is cube plastic packaging bag of the prior art.
Symbol description:1- plastic packaging bags, 11- fronts, the 12- back sides, 13- right flanks, 131 right side fold lines, 14- left sides
Face, 141 left side fold lines, the joint places of 15- first, the joint places of 16- second, the joint places of 17- the 3rd, the joint places of 18- the 4th, 19-
5th joint place, 2- openings, 21 floding at boundary lines, 22 binding faces, 3 cutting lines, 4 blind ends.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to be that the purpose of this utility model, technical scheme and advantage are clearer
The specific mode of having a try of type is described in further detail.
A kind of cube plastic packaging bag 1, bag body are straight plastic film tube, and one end of straight plastic film tube is openend 2, separately
One end is blind end 4, and Fig. 1 is the expanded view among the back side of the utility model cube plastic packaging bag during longitudinally cutting, such as
Shown in Fig. 1, cube plastic packaging bag 1 includes 14 4 front 11, the back side 12, right flank 13, left surface faces, plastic-film packing bag 1
For straight plastic film tube, longitudinal direction is splitted as single piece of material among the back side, as shown in Fig. 2 be slicing line 3 among the back side, positive 11
It is trapezoidal with the bottom of the back side 12, rectangle is connect under trapezoidal；The left surface 14, the bottom of right flank 13 are trapezoidal, and rectangle is connect under trapezoidal；
There is vertically folded line among left surface 14, right flank 13, be respectively left side fold line 141 and right side fold line 131；Right flank
Binding face 22 of the binding face 22 of 14 bottom two respectively with corresponding positive 11 and the back side 12 is bonded, and forms as shown in Figure 2
Two joint places 16, the second joint place 17；14 liang of binding faces 22 of left surface respectively with corresponding positive 11 and another patch at the back side 12
Conjunction face 22 is bonded, and forms the 4th joint place 19 and the 3rd joint place 18 as shown in Figure 2.The bottom in 12 faces of front 11 and the back of the body
Two horizontal abutment faces 22 are bonded, and form the first joint place 15, thus, form cube plastic packaging bag.First joint place 15 with
Second joint place 16, the 3rd joint place 17, the 4th joint place 18, the 5th joint place 19 are in 90 ° of intersections.
Cube plastic packaging bag of the prior art as shown in Figure 3, joint place intersect out of plumb, during use easily from
Infall is torn.
Preferably, each joint place laminating type is blanching treatment, blanching treatment process operation is convenient, and heat seal seam is in nine
Ten degree of intersections, make plastic bag packaging bag not easy to crack.
Those of ordinary skill in the art are it is envisioned that each joint place can also use the modes such as bonding.
By the foldover design of two sides, strutting packaging bag, trailing flank area is larger, and interior space is larger.Finished product
Cut by blowing cylindrical material one-shot forming, then heat seal, blanking is simple, convenient processing.
Although the utility model combination above example is described, the utility model is not limited to above-mentioned reality
Example is applied, and is only defined by the appended claims, those of ordinary skill in the art readily can modify and change to it,
