Abstract
The utility model discloses a valve port packaging bag comprising a bag body and a valve port communicated with an inner cavity of the bag body, wherein the bag body comprises outer-layer kraft paper, middle-layer kraft paper and inner-layer kraft paper, the high-strength dual-polished kraft paper serves as the inner-layer kraft paper, and a moisture-proof film is arranged between the inner-layer and middle-layer kraft paper. As the high-strength dual-polished kraft paper serves as the innermost layer of the valve port packaging bag, the tensile and compressive strength of the packaging bag are higher, the bearing capacity of the packaging bag is better, and thus the packaging bag is not damaged when being carried and squeezed; and as the moisture-proof film is arranged between the inner-layer and middle-layer kraft paper, the packaging bag achieves the waterproof, greaseproof and moistureproof aims, so that after materials packaged by the packaging bag are laid aside for one year, the moisture of the materials is not increased obviously.
Description
Technical field
The utility model relates to a kind of packaging bag, especially a kind of valve port packaging bag.
Background technology
Existing valve port packaging bag is generally the packaging bag of three layers of common craft paper.This packaging bag is once irritated wrap molding through port of valve port packaging machine, need not the closer package.Material is filled back packaging bag valve port and sealed voluntarily, and is easy, quick, packaging efficiency is high.
There is following shortcoming in use in existing packaging bag: packaging bag intensity is relatively poor, load-carrying capacity is little, breaks easily when packaging bag carrying and extruding; Kraft paper bag is non-moistureproof, and material is placed a period of time material moisture can increase out of reach waterproof, grease proofing, damp-proof purpose.
Summary of the invention
Goal of the invention: the purpose of the utility model is the above-mentioned shortcoming that overcomes existing valve port packaging bag, provides a kind of solid reliable, waterproof, grease proofing, valve port packaging bag that powder material is packed in good being used to of moisture effect.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of valve port packaging bag; It comprises bag body and the valve port that is communicated with bag body inner chamber; Said bag body comprises outer craft paper, middle level craft paper and inner layer kraft, and said inner layer kraft adopts the two light craft papeies of high strength, between inner layer kraft and middle level craft paper, the poly-vinyl damp-proof membrane is set.
In the utility model, further, said valve port is provided with extension valve port inwardly with the junction of bag body inner chamber, and the length of said extension valve port is 10mm.
Beneficial effect: 1) because the innermost layer of the valve port packaging bag of the utility model adopts the two light craft papeies of high strength, and tension, the compressive strength of packaging bag are higher, bearing capacity is better, does not have breakage in the carrying and the squeeze bag period of the day from 11 p.m. to 1 a.m; 2) after between inner layer kraft and the middle level craft paper damp-proof membrane being set, make packaging bag can reach waterproof, grease proofing, damp-proof purpose, packing materials were placed after 1 year, and material moisture can not increase; 3) in the valve port inboard extension valve port is set, has prolonged the closure size at packaging bag valve port place, the better tightness of packaging bag; 4) two light craft paper smooth surfaces, material is difficult for being bonded on the sack, is easy to discharging, is suitable for packing various powderies, granular material.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the generalized section of the bag body of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As illustrated in fig. 1 and 2, the utility model discloses a kind of valve port packaging bag that is used to pack powder material, it comprises bag body 1 and the valve port 2 that is communicated with bag body 1 inner chamber.Bag body 1 comprises outer craft paper 3, middle level craft paper 4 and inner layer kraft 5, and inner layer kraft 5 adopts the two light craft papeies of high strength, makes the tension of packaging bag, compressive strength higher like this; Bearing capacity is better; There is not breakage in the carrying and the squeeze bag period of the day from 11 p.m. to 1 a.m, and two light craft paper smooth surface, material is difficult for being bonded on the sack; Be easy to discharging, be suitable for packing various powderies, granular material.Between inner layer kraft 5 and middle level craft paper 4, poly-vinyl damp-proof membrane 6 is set, makes packaging bag can reach waterproof, grease proofing, damp-proof purpose, packing materials were placed after 1 year, and material moisture can not increase significantly.
Is the extension valve port 7 of 10mm at valve port 2 with bag length that the junction of body 1 inner chamber is provided with inwardly, extends the closure size that valve port 7 has prolonged packaging bag valve port place, makes the better tightness of packaging bag.
The valve port packaging bag that the utility model a kind of is used to pack powder material can be used for packing and is prone to absorptive inorganic powder material, comprises aluminium oxide, aluminium hydroxide; Magnesia, magnesium hydroxide, calcium carbonate; Zinc oxide, Firebrake ZB etc., the material moisture in the packaging bag is under common condition of storage; Moisture growth in 12 months is no more than 25% of initial moisture, can reach the purpose of controlling the moisture growth of packing materials in storage process effectively.
A kind of valve port packaging bag that is used to pack powder material of the utility model; When being used for the inorganic particle such as aluminium hydroxide and magnesium hydroxide of surface of package coating modification; Material moisture in the packaging bag is under condition of storage usually, and the moisture in 12 months increases and is no more than 15% of initial moisture.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
