<p>In an automatic filling and closing process for flexible package in which a film (18) is supplied while being longitudinally fused, and the respective steps of filling the longitudinally fused film (18) with the contents, laterally fusing the film (18) and cutting the laterally fused area are performed, a slit (5) or a hole (11) is intermittently formed in the supplied film (18) at a site from unwinding of the film (18) to the longitudinal fusing during interruption of the supply of the film (18) in the steps of lateral fusing and cutting, and an opening fusing tape (6) is placed over said slit (5) or hole (11) to weld around the circumference of said slit (5) or hole (11), thereby obtaining a tape-sealed bag easily openable in approximately parallel with the laterally fused area. According to the invention, the technique of opening the bag by means of the easily openable fusing tape (6) using the film (15) having a relatively low separation strength can be applied to the pillow type bag which can be efficiently produced by use of the automatic filling and closing machine for flexible package. <IMAGE></p> |
