Selective tamper resistance for on-package peelable premiums

In a carton constructed from laminated packaging material which comprises a substrate of paperboard and an outer ply of paper adhered thereto by a water soluble laminant and including a section manually removable therefrom, said section having utility, per se, apart from said container and being defined by a tear outline comprising a series of cuts through said paper in a configuration having a starting edge for initiating peeling action and an oppositely disposed trailing edge interconnected with said starting edge by opposed side edges, a release coating applied between the underside of said section and said laminant in a pattern rendering predetermined areas of said section non-adherent to said substrate, said pattern defining spaced apart voids in said release coating extending along said starting edge enabling selective adherence of said section to said substrate at said voids, said voids being in predetermined shapes enabling variable degrees of bonding between said section and said substrate as peeling of said section progresses from said leading edge into the interior areas thereof, and a water resistant coating applied to the outer surface of said paper in a pattern defining a void window area bounding said leading edge and enabling application of moisture to the area of said leading edge to dissolve said laminant at said leading edge voids preparatory to the peeling of said section from said structure.
