Selective tamper resistance for on-package peelable premiums

摘要

A laminated carton comprising a paper board substrate and an outer paper ply including a peelable section in the paper ply defined by a perforated tear outline providing a leading edge, said ply being bonded to the substrate by a water soluble laminant coated with a release agent in a pattern which includes voids in the coating at said leading edge, said voids being shaped to provide variable adhesive bond between said plies as peeling of said section is initiated after application of moisture to the area of said leading edge to dissolve said laminant at said voids.
