Specific implementation mode
It is detailed in conjunction with attached drawing in the part in order to clearly illustrate the above objects, features, and advantages of the utility model
Describe bright specific embodiment of the present utility model in detail.Other than each embodiment described in this part, the utility model
It can also be implemented by other different modes, without prejudice to the spirit of the present invention, those skilled in the art
It can be correspondingly improved, deform and replace, therefore the utility model is not limited by specific embodiment disclosed in the part.This
The protection domain of utility model patent should be subject to claim.
Referring to FIG. 2, the utility model provides a kind of heat sealed package bag, which is made of polythene material,
With front 11, reverse side 12, left side 21, right side 32, bottom edge and top opening, front 11 and aspect can be collectively referred to as interarea,
Left side 21 and right side 32 can also be collectively referred to as side.
For convenience of description, it defines：Two sides arrange that two interareas are wrapped along heat-sealing along " width direction " of heat sealed package bag
" thickness direction " arrangement of pack, top opening and bottom edge are arranged along " short transverse " of heat sealed package bag.
For heat sealed package bag by rectangular packaging bag embryogenesis, which is single layer, two opposite side of packaging bag embryo
Docking forms the abutment joint 40 of packaging bag, and the width of the abutment joint 40 is 10 millimeters.As shown in Fig. 2, the abutment joint 40 is formed in
The place of docking of right side 22 and front 11, the butt joint edge and the butt joint edge in front 11 of right side 22 are connected to each other together, thus, this is right
What seam 40 was formed by hot sealing process is double-layer structure, and two layers of the double-layer structure pass through interarea and side shape respectively
At.
The front 11 of heat sealed package bag and reverse side 12 are single layer, and left side 21 and 22 through-thickness of right side all have
Two layers, two layers of each side are connected to each other to form the cross section of the meander-shaped of side.In this embodiment, often
Two layers of a side form the cross section of M shapes with the single layer for two interareas being connected, to have four-layer structure.This four layers
Structure is squeezed tightly between together by hot sealing process, to form sealing in the side of the heat sealed package bag.
Two interareas of heat sealed package bag and the lower end of two sides are formed the bottom edge of sealing by sealing, in this way, two
Interarea, two sides, four-layer structure and the bottom edge of sealing form the vessel that can accommodate material, and material can be by top opening
Enter the vessel.
In this way, after being packed into material from top opening, left side 21 and front 11, the junction and right side of reverse side 12
22 are heat-sealed with front 11, the junction of reverse side 12 and finish, and front 11 to be sealed and reverse side are only existed at top opening
12.The encapsulation yield of packaging bag has very big association, the hot sealing layer of different number to be correspondingly applicable in different heat-sealings with heat-sealing temperature
Temperature, for the user of packaging bag, the heat sealed package bag of embodiment offer, which reduces the adjusting to heat-sealing temperature, to be needed
It asks, it is no longer necessary to seal the heat-sealing temperature of four-layer structure, and only adjust and keep the heat of 12 the two of heat-sealing front 11 and reverse side
Seal temperature.
Further, since abutment joint 40 is formed in dock place of the interarea with side, thus, when sealing top opening, it is not present
Since single interarea caused by being laminated locally has double-layer structure, locally there is three-layered node into two interareas may be not present
Structure is only used only two interareas of heat-sealing temperature pair needed for double-layer structure and is sealed i.e. for the user of packaging bag
Can, it provides convenience for user and ensures the encapsulation yield at top opening.
By test, the sealing fraction defective of the heat sealed package bag of the present embodiment is only 0.8%, this and heat in the prior art
3.75% sealing fraction defective of package pack, which is compared, reduces 80%.
Above-mentioned four-layer structure is adjoined top opening in the short transverse of heat sealed package bag and is formed, and forms the first seal area
Domain 31, first sealing area 31 are formed as rectangular, form two along the width direction and short transverse of heat sealed package bag respectively
Adjacent edge.
Adjoin at the first heat-sealing region along the width direction of heat sealed package bag and is formed with the second sealing area 32, front 11
It is formed to press together to form second sealing area 32 via hot sealing process with reverse side 12, second sealing area 32 is at side
Shape forms two adjacent edges along the width direction and short transverse of heat sealed package bag respectively.
Second sealing area 32 is docked with the first sealing area 31, and the second sealing area 32 is along the width side of heat sealed package bag
To the length with 0.5 millimeter.Second sealing area 32 is formed between two interareas, can ensure that person's sealing to be used is
Two layers of front 11 and reverse side 12.
First sealing area 31 forms the short transverse that can utilize heat sealed package bag to greatest extent close to top opening
Size more accommodates material.
First sealing area 31 and the second sealing area 32 all have scheduled sealing area, so that it is guaranteed that sealing effect.
Although the first embodiment of heat sealed package bag provided by the utility model is described in detail above, also with
Lower several points need to illustrate：
1. heat sealed package bag can also be made of other materials, for example there are many compound made of the Material cladding of characteristic
Material.
2. the side of heat sealed package bag can have three layers of the through-thickness arrangement being connected to each other, four layers etc.,
So the side then forms three-decker, four-layer structure etc. via hot sealing process with two interareas.
3. abutment joint can be formed in two sides and two interareas four dock any one of place, and are not limited to just
Place is docked with right side in face.
4. abutment joint can also be formed in the following manner：The butt joint edge of side surrounds the butt joint edge of interarea to form three
The butt joint edge of layer structure or interarea surrounds the butt joint edge of side to form three-decker.
5. the width of abutment joint is not limited to 10mm, if it can ensure sealing effect and take into account heat-sealing cost, such as
Can be 7mm between 14mm.
6. the second sealing area can be not limited to 0.5mm along the length of the width direction of heat sealed package bag, as long as can either
The filling of material is sealed conducive to user and then subsequently and do not significantly affected, for example can be 0.3mm between 0.7mm.
7. the visual angle of " just " negation " left side " " right side " referred to herein reference chart 2 is described, do not constitute to this practicality
Novel limitation.
Above each embodiment is without prejudice to can arbitrarily be combined within the scope of the spirit of the present invention.Succinctly to rise
See, there is omitted herein the descriptions of parts thereof, however the parts thereof should all be interpreted as that the prior art can be used real
It applies.
