Printing ink adhesion (Tesa test)
Self-adhesive tape test (Tesa test), Sun Chemical-Hartmann_PV-No.1 or ASTM F 2252
In short — AI-generated
The Tesa test evaluates how well printing ink or coatings adhere to the surface of flexible packaging materials. A standardized adhesive tape is applied to the printed surface under defined pressure and then removed at a specific angle and speed to observe if any ink is transferred to the tape.
The result indicates the bond strength between the ink and the substrate, helping to identify potential risks of ink flaking or transfer during further processing or use. This test is used in practice to ensure that packaging designs remain intact and legible throughout the supply chain.
