Abstract (en)
To provide a filling and packaging method and a filling and packaging machine that can reliably eliminate a risk of inclusion of bacteria in a content filled in a tubular packaging material even when a vertical sealing failure occurs in a connection portion of a web-like packaging material. The filling and packaging method includes: detecting whether a connection portion W10 of a web-like packaging material W has passed through a predetermined position in a movement path of the web-like packaging material W; reducing a supply amount of a content into a tubular packaging material T based on detected passage information of the connection portion W10, to reduce a content filling level in the tubular packaging material T from a normal position L1 above a pressure flange 18 to a negative pressure occurrence avoidance position L2 below the pressure flange 18 before the connection portion W10 reaches an expected negative pressure occurrence area A where a negative pressure is likely to occur along with pulling-down of the tubular packaging material T by a pair of sealing jaws 161; and returning the content filling level from a negative pressure occurrence avoidance position L3 to the normal position L1 after the connection portion W10 passes through the expected negative pressure occurrence area A.
