Abstract:
A filling method is disclosed in which a liquid is filled into a small packaging bag for liquid and this packaging bag is sealed, the packaging bag being constituted of a multilayered laminate (15) comprising at least three layers in which a base (13) serving as a surface layer, an interlayer (12), and a sealant layer (11) serving as an inner layer have been superposed in this order. The filling method is characterized by comprising the step of forming the main body (16) of a small bag for liquid, the step of filling the liquid thereinto, and the step of sealing the opening of the main body (16) of a small bag for liquid, wherein the interlayer (12) has been formed from a composition containing an ionomer of an ethylene/unsaturated carboxylic acid copolymer. The method is further characterized in that the filling temperature width as determined by a specific method is 30ºC or more at each of line speeds of 20 m/min and 25 m/min.
