Multiple Pressure-Sensitive Adhesive Tamper-Evident Label

Tamper-Evident Label with Multiple Pressure-Sensitive Adhesives of Different Sensitivity

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.
