Description
Technical field
It the utility model is related to plastics packed technical field, more particularly to a kind of light degradation pressure-resistant plastic film packaging
Bag.
Background technology
Plastic packaging bag is a kind of the most frequently used packaging material.Manufacture the most common material of packaging bag have transparent plastic film and
Plastimets film.
Transparent plastic film species is very much, raw materials used usually to have PE, PET, PC, PVC, nylon etc..Its transparency is preferable,
By packaging bag it can directly be seen that built-in article, Costco Wholesale are relatively low.
At present when packing some articles except filling article, it is also necessary to the air for filling corresponding proportion enters packaging bag,
It is but special when such possibility packed stacking stacking, a superpressure generation will be had when stacked items are excessive, this meeting
Damage packaging tears it, causes the leakage of article, causes unnecessary waste, while bring greatly inconvenience and fiber crops to user
It is tired.
The content of the invention
To solve above-mentioned technological deficiency, the utility model provides a kind of light degradation pressure-resistant plastic film packaging bag,
Can effectively it prevent due to the problem of packaging bag is damaged caused by superpressure.
Technical solution is used by the utility model solves its technical problem：A kind of light degradation pressure-resistant plastic film packaging
Bag, it is characterised in that：Including packaging bag body, the packaging bag body is made of the flexible plastic film with air-breather
One include front cover, rear front cover, the first side seal face and the hollow cavity in the second side seal face；The plastic film is configured
To be at least double-layer films in some areas, and internal vents are provided with interior film, external exhaust gas is provided with outer film
Hole；The internal vents and external venting, which are respectively separated, to be arranged in parallel, and is at least separated by three millimeters.
At least one wall of packaging bag body described in the utility model is made of double-plastic.
Packaging bag body described in the utility model is integrally made of double-plastic.
Internal vents and external venting described in the utility model are evenly distributed on whole double-plastic.
Packaging bag body top described in the utility model is provided with upper lateral seam, and lower part is provided with lower, transverse and connects
Seam.
Plastic film described in the utility model is polyethylene film.
Overlapping region is provided with front cover described in the utility model.
Overlapping region width described in the utility model is 50 to 70 millimeters.
The beneficial effects of the utility model are：
(1) a kind of light degradation pressure-resistant plastic film packaging bag of the utility model is used, can effectively be prevented due to superpressure
Caused by packaging bag it is damaged the problem of；
(2) a kind of light degradation pressure-resistant plastic film packaging bag of the utility model, design structure is simple, easy to process, and can
To carry out light degradation, environmental pollution is reduced.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1st, packaging bag body, 2, plastic film, 3, front cover, 4, rear front cover, the 5, first side seal face, the 6, second side
Front cover, 7, overlapping region, 10, external venting, 11, internal vents, 18, upper lateral seam, 19, lower, transverse seam.
Embodiment
Presently in connection with attached drawing, the technical scheme in the utility model embodiment is clearly and completely described, this figure is
Simplified schematic diagram, only illustrates the basic structure of the utility model in a schematic way.
According to Fig. 1, one embodiment of the utility model, including packaging bag body 1, the packaging bag body 1
One includes front cover 3, rear front cover 4, the first side seal face 5 and second made of the flexible plastic film 2 with air-breather
The hollow cavity in side seal face 6；Overlapping region 7 is provided with the front cover 3 of packaging bag body 1, wherein in process of production, modeling
Two overlapped ends of material film 2 are connected with each other by hot pressing on overlapping region 7.In the packaging bag body 1 of utility model,
Exhausting-gas hole can be arranged in the optional position outside join domain 7, overlapping region 7 can using width as 50 millimeters and 70 millimeters it
Between, this is to be enough to ensure that safe plastic film bonding；External venting 10 is arranged in the downside folded portion of side wall 5, and
It is arranged only in the outer layer of double-layer plastic film 2, internal vents 11 are arranged in the upside folded portion in side seal face 5, and only cloth
Put the internal layer in two layers of plastic film 2, and it is inreal in the figure as it can be seen that because they are covered by outer layer, but paint herein
Make so that it understands, the packaging bag body 1 for being commonly stored in outer moisture, it is therefore necessary to from external venting 10 vertically to
On internally exhausting-gas hole 11 move up.Therefore, an effective moisture-proof guarantee.It is also possible for being vented at the same time.Preferably exist
Similar exhausting-gas hole is added in second side seal face 6.At top, packaging bag body 1 is closed by upper lateral seam 18, and bottom is by under
Portion's transverse joint 19 is closed, and the utility model plastic film 2 is polyethylene film, can carry out light degradation, reduce to environment
Pollution.
