Abstract
The invention discloses a kind of non-porous exhaust packaging bag, including bag body, the bottom of the bag body is sealed with bonding wire, and the bonding wire is that at least two stripe pitch are not less than 2mm, and breakpoint is both provided with every bonding wire.The configuration of the present invention is simple, implementation cost is low, to existing product appearance without any change, solve due to body intensity decreases caused by punching, and easily make moist for the higher product of some water imbibitions, or even the product of some foodstuffs is also easy to microbial contamination, causes the irreversible loss of product.
Description
Technical field
The present invention relates to packing technique, more particularly to high-grade packaging bag.
Background technology
Currently on the market be used for packaging tealeaves, food, etc. various product packaging bag, particularly high value powder product bag
Pack, in sack after the completion of packaging there are more air be difficult discharge, which results in the bag body volume after the completion of packaging compared with
Greatly, storage takes larger space, and transport inconvenience, is easily broken, meanwhile, it cannot be finished in time after opening for some things,
Cause seal failure and make moist, volume becomes larger bag body after opening, places and takes larger space.
Patent CN201020174259.5 discloses a kind of Unidirectional air guiding valve packaging bag, and there are three side seals to close a side opening
Bag body, one plane of bag body is equipped with the Unidirectional air guiding valve being only outwards vented, and one layer of anti-skidding gloss oil is coated with bag external surface.
The bag body has four vertical planes, and along its, each vertical axis is respectively equipped with a vertical broken line on its two sides, vertically
The side at place is divided into two parts by broken line, and the two parts can vertically folding line be together.Vertically on broken line a little to
Two sides in parallel each extend over out an oblique broken line on the side of place, and extend on two sides, and two oblique
It is identical to the extending direction of broken line.Two oblique broken lines are symmetrical as symmetry axis using vertical broken line.The bag body is aluminium
Paper tinsel bag body.The one side sealed in bag body is pasted onto on bag outside by glue.The packaging bag is easily by the air in sack
Discharge, and it is easy to pile, storage.
The invention realizes packaging final vacuum and reduces volume, but when arrival consumer opens sack at one's side, it is original close
Bag mouth sealing will fail, and when consumer cannot be disposable complete, just it can not be sealed again.In addition the product structure
Excessively complicated, production, cost of transportation are high.
For the development of packing technique, the packaging bag with PE inner bags is widely used in the fine industry such as food, chemical industry, quilt
Value of Packaging Products height, waterproof, moisture-proof, security requirement is high.The packaging bag with PE inner bags generally uses pin in the prior art
Roller is punched to PE inner membrances to realize the outer row of air in sack, after the completion of packaging product is filling its internal gas in stacking slowly
Discharge, avoid the weight of palletization be continuously increased caused by bag breakage, but this mode exhaust mode due to punch not only
Make the integral strength of PE inner bags reduce, and easily make moist for the higher product of some water imbibitions, or even some foodstuffs
Product is also easy to microbial contamination, causes the irreversible loss of product.
The content of the invention
In order to solve the deficiencies in the prior art, the present invention provides a kind of non-porous exhaust packaging bag.
The technical scheme is that：A kind of non-porous exhaust packaging bag, including bag body, the opening of the bag body is opening,
Bottom is sealed with bonding wire, and the bonding wire is that at least two stripe pitch are not less than 2mm, and breakpoint is both provided with every bonding wire.
Further improvement of the present invention includes：
Breakpoint on the bonding wire is shifted to install with adjacent bonding wire breakpoint.
The bonding wire is two, and its spacing 5mm, two bonding wire breakpoints are located at bonding wire both ends respectively.
The bonding wire is wavy.
The packaging bag packs inner bag for PE.
The configuration of the present invention is simple, implementation cost is low, to existing product appearance without any change, solves since punching causes
Body intensity decreases, and easily make moist for the higher product of some water imbibitions, or even the product of some foodstuffs is also easy to
Microbial contamination, causes the irreversible loss of product.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1st, bag body, 2, bonding wire, 3, notch.
Embodiment
Elaborate below in conjunction with the accompanying drawings to the present invention.
As shown in Figure 1, a kind of non-porous exhaust packaging bag of the present invention, including bag body, the bottom of the bag body are sealed with bonding wire,
The bonding wire is that at least two stripe pitch are not less than 2mm, and breakpoint is both provided with every bonding wire.Breakpoint and phase on the bonding wire
Adjacent bonding wire breakpoint shifts to install.The bonding wire is two, and its spacing 5mm, two bonding wire breakpoints are located at bonding wire both ends respectively.Institute
It is wavy to state bonding wire.The packaging bag packs inner bag for PE.
Embodiment
Applicant is respectively with sack of the present invention and the original patented product punching sack (CN201621020869.3) of applicant
Being transported for long-distance with identical product flour, (transport of two weeks stores experiment, and returns to the moisture done behind Tianjin and microorganism
Test) moisture is tested afterwards.The sack of the present invention that the present embodiment uses is two parallel bonding wire, spacing 5mm, and breakpoint is located at bag
Body both sides.Sealed at filling after-opening with bonding wire, aqueous weight testing method uses the test method in national standard.
Table one
As shown in Table 1, this product has reduction for moisture in flour and content of microorganisms relative to control group.
It reduces reason and is found after applicant's validation trial due to the electrostatic force and capillary effect between PE films, causes PE films to exist
Tightly it is bonded all the time when external and internal pressure is consistent, it is entirely avoided air exchanges, and has further completely cut off the entrance of moisture.Meanwhile by
Partial moisture is inevitably brought into when filling in inside, and the partial moisture gasifies when temperature raises, air pressure in bag
More than external pressure, gas overflowing in bag, after pressure balance, the PE films between bonding wire are tightly bonded, i.e., when in bag air pressure it is little
When external pressure, any gas exchanges do not occur.When air pressure is more than external pressure in bag, particularly raised in external temperature,
After bag inside points moisture vaporization, air is discharged by long and narrow exhaust passage in bag, while takes away partial moisture, works as air pressure balance
When air exchange terminate.
The configuration of the present invention is simple, implementation cost is low, to existing product appearance without any change, solves since punching causes
Body intensity decreases, and easily make moist for the higher product of some water imbibitions, or even the product of some foodstuffs is also easy to
Microbial contamination, causes the irreversible loss of product.The present invention does not have any wound for bag body, ensure that the entirety of bag body
Mechanical strength, particularly PE bands (bag), ensure that integrality and security during transporting and storing for a long time.
The basic principles, main features and the advantages of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
