ABSTRACT:
A tamper-evident closure seal is imprinted on its top surface to form a pattern of adjoining matte and high-gloss areas. The bottom surface of the seal is coated with a permanent adhesive. The seal may be used to bridge a gap between two perpendicular surfaces of a carton. If unauthorized entry to the carton is gained by cutting the seal along the gap, that entry can be detected even if the carton is resealed by overlapping the closure seal in register with a transparent seal of the same size and shape. The unauthorized entry will be evident, because the pattern on the original closure seal will not be visible through the overlaid transparent seal.
