【Sovereign Items】 1. A vertical packaging bag including a bag body, a bag mouth, and a bag bottom. The bag body is composed of a front face of the bag body and a back of the bag body. The bag bottom is sealed with the front face of the bag body and the lower edge of the back face of the bag body. The sealing part forms an arc-shaped sealing area with an upward peripheral edge. The bottom of the bag is folded inward, and an inward fold line is formed in the middle. The front surface of the bag body and the back surface of the bag body are sealed at both sides to form a sealing strip. It is that: at least two connecting punches are respectively provided at the overlapping portions of the two sealing strips and the sealing area.

【Abstract】 Upright packaging bag, including bag body, bag mouth and bag bottom. The bag body is composed of the front face of the bag body and the back of the bag body. The bag bottom is sealed with the front face of the bag body and the lower edge of the back of the bag body respectively. The part forms an arc-shaped sealing zone with a peripheral upward direction. The bottom of the bag is folded inwards, and an inward fold line is formed in the middle of the bag. The front side of the bag body and the back side of the bag body are sealed at both sides to form a sealing strip, characterized in that: The overlapping portions of the sealing strip and the sealing area are each provided with at least two connecting punches. The above two or more connection punching holes are beneficial to strengthen the heat sealing strength of the bottom of the packaging bag, so that the heat sealing part is not easy to crack. When the packaging bag is loaded into the goods and placed upright, the connection punching becomes the fulcrum of the force, According to the mechanics design principle of the fulcrum, after the composite film is subjected to external force, the effect of buffering the external force is achieved through its own heat-sealing strength and deformation, which can not only reduce the bag-breaking rate but also solve the phenomenon of collapse of the packaging bag. The packaging bag is suitable for use. In large volume packaging.
