[0002] The edge sealing of packaging bags is used to seal the edges of the bag openings, so that the entire bag can be sealed for easy storage. The packaging bags are made of film and rely on heat pressing and cutting to form a separate bag structure. Currently, a rotating heat pressing wheel is used to heat press the film. When the heat pressing wheel contacts the film, it will instantly heat and apply pressure, causing the film to have a melting position and close contact. After the melting position cools down, it will be bonded to form a sealed edge.
