Abstract

In a process and in an apparatus for making bags (50), a film (51), preferably a flexible plastic film, is fed from a suitable roll (53) and at least one indented pleated portion is made in the film (51), in particular a first and a second indented pleated portions (56, 58) having a first and a second flap (56a, 56b and 58a, 58b), wherein the corresponding indented pleated portion (56, 58) has at least one respective longitudinal end (56', 56' and 58', 58'). Advantageously, a corresponding part (56'a, 56'a, 58'a, 58'a) of the pleated portion (56a, 58a) is joined to a corresponding part (546a, 546b, 548a, 548b) of the film face (52) opposite, immediately after, or downstream of, the step of forming the pleats (56, 58) and, in any case, before making the film (12) into a tube. The invention also relates to a bag made of flexible plastic film.
