The present invention relates to a band (1) that can be stored in reel format, which has areas coated by a thermally-activatable adhesive material (2) following a coating pattern (3) that is repeated along the band with at least two main transversal strips (5a, 5b) that extend between two longitudinal edges (1c) of the band and that include areas (21) coated with a grammage of thermally-activatable adhesive material between 35 and 130 gr/m2. A specific use of the band (1) is for making mesh bags (10) and in particular to close a portion of a tubular mesh (11) by interleaving said mesh portion between two coinciding portions of the same or of two bands (1, 1) and with respective main transversal strips (5a, 5a) of the coating pattern (3) towards the mesh; applying pressure; and providing heat.
