Problems solved by technology

However, chemical fertilizers are prone to moisture and caking during storage, which will have a great negative impact on the quality of chemical fertilizers
Although the traditional fertilizer packaging bag is equipped with an inner liner, it is easy to agglomerate once the water vapor content in the storage environment is too high because it is sealed with needles and threads.
This will not only weaken the nutrient supply ability of chemical fertilizers to crops, but also make it difficult to spread chemi...

Example Embodiment

[0019] In order to better understand the present invention, the present invention will be further described below in conjunction with specific embodiments and drawings.
[0020] Such as Figure 1-2 As shown, a high-strength packaging woven bag includes a bag body 2. The upper end of the inner side of the opening of the bag body 2 is bonded with an inner lining 1 through a hot pressing process to improve the gap between the inner lining 1 and the bag body 2. The connection strength and connection smoothness. The material of the bag body 2 is woven with reinforced polypropylene fibers. This design can significantly improve the fertilizer carrying quality of the bag body 2, and can effectively extend the service life of the bag body 2, so that the bag body 2 can be repeated In use, this design makes the bag body 2 more energy-saving and environmentally friendly.
[0021] The outer side of the bag body 2 is longitudinally bonded with a hand strap 5 by hot pressing. The hand strap 5 includes at least four, and they are respectively located on the left and right sides of the front and rear ends of the bag body 2. This design can make it more convenient for people to carry the bag body 2 containing chemical fertilizers. This effectively prevents the bag body 2 from slipping off people's hands during transportation.
[0022] In order to make the hand strap 5 not only have the longitudinal enhancement ability, but also have the function of providing a hand-held force point, the length of the hand strap 5 is designed to be greater than the length of the bag body 2, and the opening of the bag body 2 Both the end and the bottom end are provided with the hand strap 5 for exerting tension on people.
[0023] In addition, in order to significantly improve the lateral load-bearing capacity of the bag body 2, a plurality of closed annular reinforcement belts 4 distributed at equal intervals are bonded along the lateral direction on the outer side of the bag body 2 in a heat-pressing manner. In order to enable the reinforcement belt 4 to provide reinforcement and reinforcement for the hand belt 5, the reinforcement belt 4 is designed on the outside of the hand belt 5.
[0024] In order to improve the waterproof performance of the inner lining 1, the inner lining 1 is designed as an independent polyethylene plastic bag. In order to further enhance the waterproof effect of the inner lining 1, how long a non-woven bag is bonded on the inner side of the inner lining 1. The non-woven bag contains a granular desiccant. The non-woven bag constitutes a drying strip 6 for drying the chemical fertilizer in the bag body 2. This design enables even a trace amount of water vapor to enter the inner lining 1 during the storage of the fertilizer, the trace amount of water vapor will be absorbed by the drying strip 6, thereby creating a drier storage environment for the fertilizer.
[0025] In order to prevent the drying strip 6 from chemically reacting with the fertilizer in the bag body 2, the acidity and alkalinity of the desiccant in the drying strip 6 is consistent with the acidity and alkalinity of the fertilizer contained in the bag body 2. If the fertilizer is weakly alkaline, the desiccant will also become weakly alkaline or neutral. If the fertilizer is weakly acidic, the desiccant will also become weakly acidic or neutral.
[0026] In order to further improve the drying capacity of the drying bar 6, the number of the drying bars 6 is designed to be multiple, and the drying bars 6 are distributed at equal intervals on the inner side wall of the inner lining 1. This design can improve the inner lining 1. The efficiency with which water molecules are absorbed.
[0027] In order to improve the printing quality of the bag body 2, a printing film 3 for printing trademarks is bonded on the outside of the reinforcing belt 4 through a hot pressing process. In addition, in order to protect the printing film 3, a protective film made of biaxially oriented polypropylene is coated on the outside of the printing film 3. This protective film has the advantages of tensile resistance, high mechanical strength, good abrasion resistance, and strong water resistance.
[0028] In order to enable the protective film to act as a protective barrier for water molecules to invade the bag body 2, the protective film surrounds all sides and bottom of the bag body 2 to form a complete outer waterproof protective layer. In order to make the thermal compression bonding of the printing film 3 and the protective film more convenient, the material of the printing film 3 is designed as a biaxially oriented polypropylene film.
[0029] Finally, in order to make the opening of the bag body 2 have a better sealing effect, the openings of the bag body 2 and the inner liner 1 are connected and fixed by sutures. In order to further improve the sealing performance of the bag body 2, an elastic polyurethane sealing gasket is attached to the opening of the inner lining 1. The stitching thread connects the bag body 2, the inner lining 1 and the sealing gasket Tightly stitched together.
[0030] The embodiments of the present invention have been described in detail above, but the content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made in accordance with the scope of the present invention should still fall within the scope of this patent.
