Abstract

Flexible packages having a resealable interlocking closure made from a continuous web of flexible film, the closure being formed at line speed across o ne end of the package transversely to the direction of film flow. A converter is mounte d to wrapping machines or overwrap packagers, and uses films such as polypropylene, polyester, polyvinyl chloride, polyethylene and film laminations. The film is fa nfolded across its width to form a stack which is heat sealed into a multilayered semi-r igid strip. In one embodiment, the resealable locking feature is thermoformed into th e multilayered strip before product packaging, while in another embodiment the semi-rigid strip is formed into the resealable locking closure after product pac kaging.
