The structure of the stand-up pouch looks simple, but the design and production of this structure is complex. Due to factors such as gravity and nonuniform configuration of the contents, the use of a single-layer plastic film or a multi-layer structure of the trunk portion can easily cause structural "fatigue." In order to make the side walls strong, aluminum foil and thick plastic materials can be used to make bags that can stand upright, and single-layer films are also used.
