Description
Technical field
The utility model relates to a kind of valve bag, particularly relates to the valve bag of a kind of film opening exhaust, belongs to packing technique field.
Background technology
At present, along with the development in market, in order to adapt to the packaging demand of nano-powder material, more and more higher to the requirement of valve-port packaging bag, the double-layer characteristics particularly requiring its valve-port paper bag to have can be vented and can be moistureproof, valve-port paper bag is in order to meet this characteristic, one deck High molecular material PE film is with the addition of at the body internal layer of paper bag, by playing the enforcement of micropore technique on PE film, paper bag is made to reach the function of exhaust, because the micropore on PE film has automatic closing function, after material-filling, micropore on PE film is the closed bladder layer forming damp proof insulation automatically, reach moistureproof function.
But in order to improve the filling speed of nano-powder material high-speed, existing valve-port packaging bag beats the mode of micropore exhaust, can not meet the demand of the filling exhaust of nano powder material high-speed;
In order to the demand making valve-port packaging bag reach high-speed canning, the utility model provides the valve bag structure of a kind of film opening exhaust, and the simple and practical property of this structural manufacturing process is strong, is applicable to extensively promoting.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of structure simple valve mouth structure, and this structure can meet the exhaust demand of nano powder material at high speed canning process, improves the speed that nano powder material high-speed is canned.
For achieving the above object, the technical scheme that the utility model is taked is:
A valve bag for slice film opening exhaust, comprises paper bag body, upper bottom portion, lower bottom part; Valve mouth structure is provided with in described upper bottom portion; Described paper bag body comprises paper layer and PE rete; It is characterized in that: in described PE film, be provided with micropore and exhausr port;
Further improvement, described exhausr port and described micropore arranged in a crossed manner;
Further improvement, the quantity of described micropore is N, and parallel side-by-side is arranged;
Further improvement, described exhausr port is rectangular exhausr port;
Further improvement, the quantity of described exhausr port is N;
Further improvement, described paper layer is one deck paper layer or multi-layered paper layer;
Further improvement, described PE film is high strength Obstruct membrane;
Compared with prior art, adopt such scheme, the beneficial effects of the utility model are: the micropore of the utility model on PE film, and the exhausr port arranged in a crossed manner with micropore, increase the degassing function of valve bag inside; Meet the demand that nano powder objects at high speed is canned, improve the speed that nano powder material high-speed is canned.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1,2,3, 4, the valve bag of a kind of film opening exhaust, comprises paper bag body 1, upper bottom portion 2, lower bottom part 3; Described paper bag body 1 comprises paper layer and PE film 5; Micropore 9 and exhausr port 10 is provided with in described PE film 5; Described exhausr port 10 is arranged in a crossed manner with described micropore 9; Described exhausr port 10 is rectangular exhausr port;
Described paper layer is one deck paper layer or multi-layered paper layer; The present embodiment selects two-layer paper layer; Described PE film 5 is high strength Obstruct membrane;
Concrete, described paper bag body 1 comprises the first paper 6, second paper 7 and PE film 5; Second paper 7 is coated with last layer glue 8, the second paper 7 and the first paper 6 are bonded together; Then on the first paper 6, be also coated with last layer glue 8, the first paper 6 is bonded together with PE film 5; PE film 5 adopts high strength Obstruct membrane herein; This structure utilizes glue 8 by the first paper 6, second paper 7 together with PE film 5 quick-binding, ensure that the paper film composite structure of paper bag body 1 is shaping at the quick-binding of seam, meanwhile, serves again the firm intensity strengthening paper bag heavy duty packaging;
Described upper bottom portion 2 is provided with valve mouth structure 4; This valve mouth structure 4 can realize automatic open; Described valve mouth structure 4 is crowded around by paper to form, and formed specially to carry out canned inlet point; When not carrying out canned, the shape of described valve mouth structure 4 is flat compression shape; When canned, the shape of described valve mouth structure 4 can be tubular; One end of described valve mouth structure 4 is arranged on the side edge of paper bag body 1, and the other end stretches in the lap seam of upper bottom portion 2, and is positioned at the inside of paper bag body 1, is communicated with thorax in paper bag body 1;
The quantity of described micropore 9 is N, and parallel side-by-side is arranged; This micropore 9 is implemented by perforating device;
The quantity of described exhausr port 10 is N; This exhausr port 10 is implemented by online shedding motion;
The on-line implement while that the drilling process of described micropore 9 and the opening operation of described exhausr port 10 being, controls the free air capacity of valve bag body 1 inside accurately;
When paper bag is canned time, nano-powder material 15 can order from lower to upper progressively be filled up, micropore 9 on its PE film 5 can along with the canned of nano-powder material 15 one by one by packing, can draw thus, when nano-powder material 15 is more close to valve mouth structure 4, the exhaust rate of its paper bag can be more and more less, will reduce the canned efficiency of material like this;
The utility model arranges rectangular exhausr port 9 at the crossover location place of the micropore 9 of PE film 5 upper end; Increase the exhaust rate of paper bag, thus ensure that the exhaust rate of paper bag can not reduce with the packing of material, ensure that the exhaust rate of whole valve-port paper bag, meet the demand that the high speed of nano-powder material 15 is canned;
The micropore of the utility model on PE film, and the exhausr port arranged in a crossed manner with micropore, increase the degassing function of valve bag inside; Meet the demand that nano powder objects at high speed is canned, improve the speed that nano powder material high-speed is canned; In addition, micropore is implemented online by perforating device, and exhausr port is also implemented by online shedding motion, and this two procedures is on-line implement simultaneously, controls the free air capacity of valve bag inside accurately.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
