[0002] Food packaging bags are generally made of PE (polyethylene) and PP (polypropylene). Due to the ease of molding plastics, there are many different shapes of food packaging bags on the market. Currently, there are many types of self-standing and folding packaging bags available on the market, which consumes a lot of material. Generally, self-standing packaging bags are made by forming the two ends of the sealed, pleated packaging material into square or rounded square tubes, and then folding the bottom of the square tube to form a sealed bottom, thus creating a three-dimensional self-standing packaging bag.

[0003] Most existing packaging bags have a fixed shape. Stand-up pouches are bulky when unfolded from the bottom, making them inconvenient to transport. Closed food bags are not convenient to display on shelves. At the same time, food bags have weak preservation function, and food will spoil in hot weather and when the shelf life of the food inside is short. In order to address this technical problem, this application proposes a flat food packaging bag that can stand up from the bottom. Utility Model Content
