Abstract
Packages having web formed resealable interlocking closures of packaging film fanfolded to form a stack and heat sealed together forming a multilayered strip in plane with the film. The strip is abraded on one surface, the film passing into the package former where packages are formed having longitudinal package seals, and which places portions of the strip in apposed position. The package ends are sealed and the resealable locking closure is formed in the strip. The female portion of the locking closure is formed in the package face that includes the overlapped longitudinal package seal. Alternatively, the strip is not abraded and the inner and outer parts of the resealable closure are separately formed before package formation takes place. To form the strip, heat sealing a strip of heat sealable material to the packaging film may also be utilized. Optionally formed in the resealable closure are hinges and reinforcing V-notches.
