The process for sealing a sachet with a seal comprises moving a set of two closing bands (4,6), which have complementary profiles engaged in each other, in a longitudinal direction. A sealing film (100) is independently brought to a positioning station (G). The complementary band profiles are disengaged from each other and the two bands are progressively separated. The film is then introduced between the bands so that it is parallel to one of the bands. The bands are then re-clamped on each other until the profiles are engaged in each other together with the film. |
