Tensile Adhesion Testing

Most likely your product uses either tape or labeling in its design, manufacture, or shipment to your customer. You to be assured that these low-cost but important items provide the required performance. Westpak, Inc. offers a variety of services for evaluating the mechanical properties of pressure sensitive labels, thermal transfer labels, adhesive labels, and adhesive tape. Some of the tests are outlined below:

Peel Adhesion Testing

Per ASTM D3330, determine the peel adhesion properties of your material.  Westpak, Inc. can perform adhesion testing at either 180° or 90° peel angles.

Holding Power of Pressure Sensitive Tapes
Per ASTM D3654, the shear adhesion properties of your sample are determined when applied to a vertical surface.

Tensile Strength

Per ASTM D3759, determine the tensile strength properties of your samples in the machine direction and the cross direction.

For proprietary tests or special applications, Westpak’s engineering team can work with you to develop custom fixtures and test methods to properly evaluate your samples.
