Method for manufacturing packs (1) characterised in that it comprises steps according to which:
- a packaging film is unwound;
- a first gusset (3) is formed on the unwinding packaging film;
- a second gusset (8) is formed on the unwinding packaging film, the second gusset being formed on the same edge of the unwinding film as the first gusset (3), said second gusset being associated with a closure assembly located between its two ridges to form an opening indicator.
Pack characterised in that it comprises:
- a first gusset (3) on a packaging film;
- a second gusset (8), the second gusset being formed on the same edge of the unwinding film;
- a closure assembly (4) between the two ridges (12, 12) of the second gusset (8), said second gusset (8) then comprising an opening indicator.
Machine for manufacturing packs characterised in that it comprises:
- means able to unwind a packaging film;
- means able to form a first gusset (3) on the unwinding packaging film;
- means able to form a second gusset (8) on the unwinding packaging film, the second gusset being formed on the same edge of the unwinding film as the first gusset, the second gusset being in association with a closure assembly (4) between the two ridges (12, 13) of the second gusset (8), said second gusset forming an opening indicator.
