The procedure for manufacturing a film (50) intended to form sachets consists of moving the film and fixing sequentially on it and transverse to its displacement direction (D) a closing device (1). This device includes a first band (2) supporting a male closing section (10) engaging another complementary female closing section supported by a second band (4). Each band comprises a thin transparent section (6,8) extending laterally on one side of the sections supported by each band. |
