Description
Technical field
The present invention relates to packaging woven bag technical fields, more particularly, to a kind of Dampproof woven bag.
Background technique
In recent years, with the continuous promotion of planting technology, chemical fertilizer plays vital work during agricultural planting
With.In the different stages of growth of crops, applying different chemical fertilizer, nitrogen needed for making crops, phosphorus, potassium obtain sufficient supply,
To promote the yield of crops.However, the storage of chemical fertilizer is still an insoluble problem so far.Because of traditional chemical fertilizer
Packaging bag is sutured when due to encapsulation using needlework although being equipped with liner, so once placing the water vapour content in environment
It is excessively high to be easy for that there is a phenomenon where agglomerate.Chemical fertilizer can not only be weakened in this way to the nutrition supply ability of crops, also make chemical fertilizer difficult
To be uniformly sprinkled upon in farmland.Farmland can be thus set certain plot poor nutritional occur, certain plot is due to application chemical fertilizer amount is excessively high
The case where burn seedlings.This will result directly in being greatly reduced for crops harvest.
It can be seen that how to develop a kind of Dampproof woven bag, have that structure is simple, dampproof effect is good, using more
For convenience of the advantages of, be a problem to be solved by those skilled in the art.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of Dampproof woven bags.
A kind of Dampproof woven bag of the present invention, including bag body, bag body opening inner side upper end are viscous by heat pressing process
Liner is had, the material of the bag body is that reinforced polypropylene fibrage forms, and the liner is then independent vinyon
Bag, the liner inner adhesion has multiple strip non-woven bags, granulated dried agent is loaded in the non-woven bag, described
Desiccant and the non-woven bag are constituted for drying the dried strip for holding chemical fertilizer in the bag body；Pass through heat on the outside of the bag body
Pressure technique is bonded with for printing trader's target printing film, and it is Biaxially oriented polypropylene that the printing film outside, which is coated with one layer of material,
Protective film.
Further, the protective film is around bag body whole side and bottom to constitute complete outside waterproofing protection
Layer.
Further, the acid-base property one of chemical fertilizer is held in the acid-base property of the desiccant in the dried strip and the bag body
It causes.
Further, the quantity of the dried strip is multiple, and equidistantly distributed is on the liner side wall.
Further, the material of the printing film is bidirectional stretching polypropylene film.
Further, the bag body and the opening of the liner are connected and fixed by suture.
Further, the liner opening is fitted with elastic polyurethane gasket seal, the suture by the bag body,
Liner and the gasket seal tight suture are integrated.
A kind of Dampproof woven bag of the present invention, has the advantage that compared with prior art
In the Dampproof woven bag, by the way that the bag body is designed as reinforced polypropylene fibrage into the chemical fertilizer for making bag body
Bearing capacity is stronger, while because the quality of bag body is significantly improved, it is possible to the significant service life for extending bag body.It is described
The design of liner can be effectively prevented outside moisture and enter in the liner, and the design of the dried strip then makes in the liner
Chemical fertilizer keep dry and provide more sound assurance, and on the one hand printing quality can be improved in the outer layer printing film, separately
On the one hand the invasion of moisture then can be effectively prevented；And then on the one hand protection printing trader is marked with chemical fertilizer for the design of the protective film
On the other hand related description can provide good waterproof and dampproof barrier then for the chemical fertilizer in bag.The design generally speaking structure
It is relatively simple, it is easy to accomplish, and can significantly improve the status that chemical fertilizer is easy dampness agglomeration, so that chemical fertilizer be made to be easier to store
With use.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is installation diagram of the invention.
In figure: 1, liner, 2, bag body, 3, protective film, 4, printing film, 5, dried strip.
Specific embodiment
In order to better understand the present invention, the present invention is further described with attached drawing combined with specific embodiments below.
As shown in Figs. 1-2, a kind of Dampproof woven bag, including bag body 2, the 2 opening inner side upper end of bag body pass through heat
Pressure technique is bonded with liner 1, to improve the bonding strength and connection planarization between the liner 1 and the bag body 2.The bag
The material of body 2 is that reinforced polypropylene fibrage forms, which can be obviously improved the chemical fertilizer carrying quality of the bag body 2,
And can effectively extend the service life of bag body 2, the bag body 2 may be reused, thus the design makes the bag body 2 more
For energy conservation and environmental protection.
In order to improve the waterproof performance of the liner 1, so the liner 1 design is independent polyethylene plastic bag.
In order to further enhance the waterproof effect of the liner 1, so having multiple strip non-woven fabrics in 1 inner adhesion of liner
Bag, granulated dried agent is loaded in the non-woven bag, the desiccant and the non-woven bag are constituted for described in drying
The dried strip 5 of chemical fertilizer is held in bag body 2.Even if the design is so that chemical fertilizer has micro vapor to enter institute in storing process
It states in liner 1, these trace amounts of water vapor can also be sponged by the dried strip 5, thus more dry for chemical fertilizer construction one
Storage environment.
In order to enable the dried strip 5 not chemically react with the chemical fertilizer in bag body 2, so making the dried strip 5
It is consistent that the acid-base property of chemical fertilizer is held in the acid-base property of interior desiccant and the bag body 2, if chemical fertilizer is in alkalescent, then desiccant
At alkalescent or neutrality, desiccant is also at faintly acid or neutrality if chemical fertilizer is weakly acidic.
In order to further enhance the drying capacity of the dried strip 5, so being more by the quantitative design of the dried strip 5
It is a, and equidistantly distributed, in 1 internal side wall of liner, which can promote hydrone in the liner 1 and be absorbed
Efficiency.
In order to improve the printing quality of the bag body 2, it is used for so being bonded on the outside of the bag body 2 by heat pressing process
Printing trader's target printing film 4.And in order to which the printing film 4 is protected, so being coated with one on the outside of the printing film 4
Layer material is the protective film 3 of Biaxially oriented polypropylene.This protective film 3 have stretch-proof, high mechanical strength, wearability it is good,
The advantages that waterproof ability is strong.
In order to enable the protective film 3 to invade as hydrone one of protective barrier of the bag body 2, so will be described
Protective film 3 surrounds the whole sides and bottom of the bag body 2, to constitute complete outside waterproof protective layer.In order to make described hold
It is more convenient when die 4 is with 3 thermo-compression bonding of protective film, so the material design of the printing film 4 is gathered for biaxial tension
Polypropylene film.
Finally, in order to keep the bag body 2 sealing effect that is open be more good, so by the bag body 2 and the liner 1
Opening is connected and fixed by suture.In order to further enhance the sealing performance of the bag body 2, so being opened in the liner 1
It is fitted with elastic polyurethane gasket seal at mouthful, the suture is close by the bag body 2, liner 1 and the gasket seal
It is stitched into one.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention,
It should not be considered as limiting the scope of the invention.All changes and improvements made in accordance with the scope of the present invention, should all
It still belongs within this patent covering scope.
