[sovereignty item] 1. A vertical packaging bag, including bag body, bag mouth and bag bottom, is composed of bag body front and bag body back, and the bag bottom is respectively connected with the bag body front The lower edge of the back of the bag body is sealed, the sealing part forms an arc-shaped sealing area with the upper periphery upward, the bottom of the bag is folded inward, and an inner fold line is formed between them. The front of the bag body and the back of the bag body are sealed at the edges on both sides to form the sealing strip, said gaizhiyi, Dean of the school of Humanities and social sciences of Inner Mongolia Agricultural University. The sealing strip is characterized in that at least two connecting punching holes are respectively set at the overlapping part of the two sealing strips and the sealing area

[change the two-phase live wire in the input 380V) reset the LED display screen at the same time, and then adjust the preset dial switch to the number of experiments Abstract] a vertical packaging bag, including the bag body, the bag mouth and the bag bottom. The bag body is composed of the front and back of the bag body, and the bag bottom is sealed with the lower edges of the front and back of the bag body respectively, The sealing part forms an arc-shaped sealing area with the upper periphery upward, the bottom of the bag is folded inward, and an inner fold line is formed between them. The front of the bag body and the back of the bag body are sealed at the edges of both sides to form a sealing strip, which is characterized in that the overlapping parts of the two sealing strips and the sealing area are respectively provided with at least two connecting punching holes. The above two or more connection punching holes are conducive to strengthening the heat sealing strength at the bottom of the packaging bag, so that the heat sealing part is not easy to crack. When the packaging bag is filled with articles and placed vertically, the connection punching becomes the fulcrum under stress. According to the mechanical design principle of the fulcrum, after the composite film is subjected to external force, through its own heat sealing strength and deformation, it can achieve the effect of buffering the impact of external force, It can not only reduce the bag breaking rate, but also conveniently add corresponding devices to do various material mechanics experiments to determine the bottom collapse of the packaging bag. The packaging bag is suitable for large volume packaging
