Method of analyzing tamper evident tape residue

摘要

Methods and systems for measuring the effectiveness of pigment transfer in a tamper evident tape. A test area can be established on a substrate upon which a residual image is formed by pulling a tamper-evident tape. The test area is divided into a predefined number of units. Then, the number of units in which a residual is left behind on a surface of the substrate can be counted and compared to the number of units within an area of un-applied tamper-evident tape of identical application design such that a percentage of units remaining on the substrate after removal of the tamper-evident tape with the residual comprises a criterion for evaluating a relative effectiveness of the tamper-evident tape.

1. A method for measuring the effectiveness of tamper-evident tape, said method comprising:
establishing a test area on a substrate surface upon which a residual image is formed by pulling a tamper-evident tape; dividing said test area into a predefined number of units; counting a number of units in which a residual is left behind on said substrate surface; and comparing said number of units to a number of units within an area of un-applied tamper-evident tape of identical application design to determine a percentage of units remaining on said substrate surface after removal of said tamper-evident tape with said residual, the percentage comprises a criterion for evaluating a relative effectiveness of said tamper-evident tape.
