Description

This invention is a label that is coated with multiple adhesives, providing tamper detection security to multiple vulnerable environmental situations. Coating labels with only one type of adhesive allows them to be removed without any evidence of tampering. This tamper-evident label is backed with a pattern of three different types of pressure-sensitive adhesives that offset three specific potential attempts—extreme high temperatures, extreme low temperatures, and the use of common solvents—to lift the label intact.

Abstract

A tamper-evident label that includes a substrate. On the substrate is deposited more than one adhesive. Each adhesive is sensitive to a different condition. The adhesives are deposited throughout the substrate in user-definable patterns. A release layer is placed on the adhesives for ease of transport and application, but is removed prior to affixation of the tamper-evident label.
