Be staggered the structure that is stepped above and below the front of bag body, and the bottom adhe line is higher than the back side bottom edge of the bag body,
The top cementing line is less than the front top margin of the bag body.
In one preferred embodiment of the utility model, the back side of the bag body contain bonding is squeezed by hot melt adhesive and
At equivalent unit.
In one preferred embodiment of the utility model, applying hot melt adhesives layer at the bottom seal, the top closure
Place's applying hot melt adhesives layer when filling by sack user.
In one preferred embodiment of the utility model, the bottom adhe line is higher than the back side bottom edge of the bag body
10mm, the top cementing line are less than the front top margin 10mm of the bag body.
In one preferred embodiment of the utility model, the trapezoidal bag is still rectangular parallelepiped structure after filling.
In one preferred embodiment of the utility model, the bottom seal of the ladder-type structure and the ladder of top closure
Shape intermediate location contains circular arc chamfering.
The utility model has the beneficial effects that：By the way that the bottom seal of bag body and top closure are designed to mistake up and down
The trapezium structure opened so that be still in cuboid after its is filling, and bottom sealing is smooth, pattern arrangement combines together, no disconnection, print
Brush can be completed once, and appearance design is beautiful, moreover it is possible to improve bottom to pulling force, keep its sealing secured, be not easy to be influenced by ambient humidity.

Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
- Fig. 3 is please referred to Fig.1, the utility model embodiment includes：
A kind of trapezoidal bag, is formed by woven cloth and BOPP Material claddings, including：Bag body 1, the bag body 1 are
Rectangular parallelepiped structure, including bottom seal 2, top closure 3, bottom adhe line 4 and top cementing line 5.
The bag body 1 includes front 11, the back side 12, left side 13 and right side 14, the back side of the bag body 1
12 by hot melt adhesive containing the equivalent unit 6 being bonded is squeezed, and the side that the equivalent unit 6 is located at the back side 12 of bag body 1 is leaned on
At nearly right side 14.
The bottom seal 2 is staggered the structure that is stepped at about 12 back side of the bag body 1, and the bottom is sealed
It is coated with hot melt adhesive layer at mouth 2.Contain bottom circular arc chamfering in the step-like transition position of the bottom seal 2 of the ladder-type structure
7, the leakage of internal filling object can be effectively prevented after hot melt adhesive bonds.
The top closure 3 is staggered the structure that is stepped in about 11 front of the bag body 1, and the top is sealed
At mouthfuls 3 by user when filling applying hot melt adhesives layer.The step-like transition position of the top closure 3 of the ladder-type structure contains
There is top arc chamfering 8, the leakage of internal filling object can be effectively prevented after hot melt adhesive bonds.
The bottom adhe line 4 is higher than the back side bottom edge of the bag body 1, and the top cementing line 5 is less than the bag
The front top margin of sub- ontology 1.In in the present embodiment, the bottom adhe line 4 is higher than the back side bottom edge of the bag body 1
10mm, the top cementing line 5 are less than the front top margin 10mm of the bag body 1.
Due to being coated with hot melt adhesive at bottom seal 2, when encapsulation, bottom seal 2 need to only be turned up along top cementing line 5, passed through
Squeeze bonding；Similarly, applying hot melt adhesives when top closure 3 is in filling, after canned, top closure 3 is along bottom adhe line 4
It turns up, is bonded through squeezing.
The trapezoidal bag of the utility model is still in cuboid through filling back pkt. body, and bottom sealing is smooth, and visual appearance degree is better than
Stitch bag, valve bag.
The utility model sound construction, bottom, better than seam bag, are coated with hot melt to pulling force at bottom seal and top closure
Glue, and bonded by squeezing, traditional needlework seam packet is substituted, avoids seam packet from being reduced to the destroying infection of woven cloth the bottom of for and draws
Power.
The utility model constructional appearance is designed beautifully, and bottom and top design can be with bag body global design, pattern
Arrangement combines together, no disconnection, print it is primary complete, can be simple to avoid valve bag bottom and top design, pattern or
Color is because aberration occurs in secondary printing, the problems such as influencing appearance.
The utility model sealing structure is excellent, better than seam bag, wiredrawn edge bag with square bottom, is suitable for packaging powdered, graininess
And other items, effectively avoid seam bag, the poorly sealed filling powdery of wiredrawn edge bag with square bottom, fine granularity and other items from leaking；It avoids
Influence of the ambient humidity to article in bag.
The utility model discloses a kind of trapezoidal bag, by the way that the bottom seal of bag body and top closure to be designed to
Under the trapezium structure that is staggered so that be still in cuboid after its is filling, and bottom sealing is smooth, pattern arrangement combines together, without de-
Section, printing can be completed once, and appearance design is beautiful, moreover it is possible to improve bottom to pulling force, keep its sealing secured, be not easy by ambient humidity shadow
It rings.
