A method of forming a reclosable gusseted bag (10) is disclosed wherein carrier tape webs (40,42) having discrete sections of mating profile (52,54) separated by profile free sections is introduced between two bag walls (32,34) and sealed to the bag wall (32,34) tops edges or adjacent thereto. The carrier tape webs (40,42) are sealed to the bag wall films (32,34) and cross seals are made in the bag wall films (32,34) and carrier tape webs (40,42) through the profile free sections. Side gussets (16,18) are formed by pushing a part of the bag walls (32,34) and the profile free sections of the carrier tape web (40,42) between the profiles (52,54) so that when the bag (10) is closed a part of the gussets (16,48) are captured between the mated profiles (52,54). A bottom gusset (10) is formed in the bag bottom and a peel seal (26) may be provided below the profiles (52,54). <IMAGE> |
