High-strength packaging woven bag

Abstract

The invention provides a high-strength packaging woven bag comprising a bag body. A lining is bonded to the upper end of the inner side of an opening of the bag body through a hot pressing process, the bag body is made of reinforced polypropylene fibers in a weaving manner, the lining is made of an independent polyethylene plastic bag, a non-woven bag is bonded on the inner side of the lining, a desiccant is contained in the non-woven bag, and the desiccant and the non-woven bag form a dry strip for drying fertilizer; at least four hand straps are longitudinally bonded to the outer side of thebag body in a hot pressing manner, the length of the hand straps is greater than the length of the bag body, the opening end and the bottom end of the bag body are both provided with the hand straps,a plurality of closed annular reinforcing tapes are bonded to the outer side of the bag body transversely through the hot pressing manner, and the reinforcing tapes are located on the outer sides ofthe hand straps; printing films where trademarks are printed are bonded to the outer sides of the reinforcing tapes through a hot pressing process; and the bag body and the opening position of the lining are connected and fixed through a suture line. The high-strength packaging woven bag has the beneficial effects that the design is more durable, the sealing performance is good, carrying is facilitated.

Description

technical field [0001] The invention relates to the technical field of packaging woven bags, in particular to a high-strength packaging woven bag. Background technique [0002] With the continuous improvement of planting technology, chemical fertilizers play an increasingly important role in the process of agricultural planting. Because in different growth stages of crops, the application of corresponding chemical fertilizers can provide adequate supply of nutrients such as nitrogen, phosphorus, and potassium required by crops, thereby increasing the yield of crops. 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 provided with a 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...

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 chemical fertilizers evenly on the farmland.

In this way, there will be a shortage of nutrients in one plot of farmland, while other plots will burn seedlings due to excessive application of chemical fertilizers.

This will directly lead to a substantial reduction in crop yields

In addition, due to the weak tensile resistance of traditional fertilizer packaging bags, their service life is short, and the surface of the packaging bags is relatively smooth during handling, so they are easy to slip from people's hands
