The ASTM D2860/D2860M-18 standard test method is used to evaluate the gluing performance of pressure-sensitive tape to fiberboard at a 90 ° angle and constant stress. This method shows the gluing performance of the tape with fiberboard at constant pressure and is suitable for performance testing of Encasement tapes. The test consists of two procedures: Step A is used for comparison with established requirements, and Step B is used for ranking the gluing ability of the tape to fiberboard. The test can use standard hanging surface Cardboard or Miscellaneous representative fiberboard, and the test results help to understand how the tape will perform in practical applications.
