Abstract
A package integrity feature for a recloseable package is provided. The recloseable package may be made from a laminate film and may comprise a scored inner layer having a machine direction and a scored outer layer laminated together with both permanent adhesive and pressure sensitive adhesive to form a recloseable flap that covers an opening in a package body. The package integrity feature may be a strip of material cut into the inner layer of the laminate film in such a way that the strip breaks when the package is opened, leaving one end of the strip attached to the package body and the opposite end attached to the recloseable flap.
