ABSTRACT:
A package is provided which incorporates a peel seal area or areas that provide readily detectable evidence that the package has been opened or tampered with. Message indicia are provided at or near the peel seal, and the appearance of the message indicia changes when the peel seal area, which has a contact clarity condition when sealed, is broken resulting in the onset of an opacity condition in a background area but not in an indicia area in order to inform a consumer or potential purchaser that the peel seal has been broken. The peel seal area is provided by impressing onto the package a heat seal bar having message indicia engraved thereinto.
