Abstract
A composite web of packaging material for making gusseted packages having openable and reclosable interlocking seals, the seals having male and female portions, snap detents, and formed transversely to the direction of material flow. The packaging material is provided at package length intervals with thermoformable strips secured thereto transversely to the running length of the packaging material, and is fed to a modified standard vertical form, fill and seal packaging machine with gussets forming tooling where the packaging material is formed into a bag with the thermoformable strips inside at the upper end of the bag, product deposited into the bag, the bag sealed, the reclosable interlocking seal formed, and the bag severed from the next bag being formed. The reclosable seal provides auditory and tactile indications of seal closing. Some packages are formed with the thermoformable strips in the gusset, and some are formed with the gusset free of strip material.
