  • Patent number: 9927337
    Abstract: Embodiments of the invention include systems and methods for determining adhesive strength of a sample label. For example, the present invention relates to a novel approach for examining the resistance to peel force required to remove a pressure sensitive adhesive (PSA) label from its intended substrate. This approach is encompassed by systems and methods which rely on the creation of one or any combination of at least four test strip types traced and cut from a label adhered to its intended substrate. The test strips may be oriented in at least three ways: along the machine direction of the label's face stock, along the cross direction of the label's face stock, and along an angle diagonal to the intersection of the machine and cross directions of the label's face stock, where the angle does not equal 0°, 90°, 180°, 270°, or 360°. The test strips may be peeled in reference to the position along the label and to and from which they extend.
