A method for packing infusion products into capsules (2) comprises a succession of steps, including: feeding empty capsules (2) along a feed line (L); filling each capsule (2) with a charge of infusion product; sealing each capsule (2) at an annular collar (2c) with a sealing portion (A) of a web of sealing film (F) using joining means (7a); separating each capsule (2) sealed by the sealing portion (A) from the remaining waste portion of the sealing film (F); between the filling step and the sealing step there is a step of pre-cutting the sealing film (F) in order to make a plurality of sealing portions (A) having a diameter (DA) that is smaller than the diameter (D2) of the annular collar (2c); the sealing portions (A) are held in contact with the rest of the film (F) by at least three radial protrusions (AP). |
