Developed paper grain bags

A packaging product that can replace the traditional grain packaging - the paper grain packaging bag was introduced in Shanghai Zhenzheng Packaging Co., Ltd. Now it has been put into the domestic market in bulk for the packaging of domestic and export flour and starch products.
The material used in this paper bag is a high-strength stretch paper, which is 1.5 times stronger than ordinary paper bags. Due to the reasonable and firm structure of the bag. For example, the bottom pockets are trapezoidal and each layer is bonded independently to make it stronger. A bag of four-layer stretch paper paper bags filled with 25 kilograms of flour is free to fall 10 times at a height of 1.2m, and still does not break the bag. Paper itself has hygroscopicity. Packaging paper in paper bags absorbs excess water in food and effectively prevents moisture from getting wet due to the environment. At the same time, the tightness of the paper bag is better than the cloth bag. Under the same conditions, the shelf life of the flour packaged in paper bags can be extended by two to three months compared with that of the bags.
The prominent advantages of the paper bag are non-toxic, odorless, non-polluting, and meet the national food hygiene standards. Because the printing performance of the paper is good, the graphic characters can be printed according to the user's request. The valve paper bag made of this paper is very convenient and rapid in the filling process of the flour, the filling speed can be increased by 3 times, and there is no dust flying, and the working environment can be improved. In addition, since the paper bag is rectangular after filling, it is easy to palletize and is not suitable for sliding. With the same capacity, the storage capacity can be increased by 10%. The handling process does not contaminate the clothes of the operator. Therefore, the promotion of the use of paper grain packaging bags is inevitable in the future replacement of grain packaging, and it is also the development trend of grain packaging in the future.
