How the Paper Tearing Tester Works

• Test Process: The SLD-02 Paper Tearing Tester operates with a precise mechanism that delivers standardized tear testing:
  1. A cutting knife creates a 43mm slit from the far edge of the sample.
  2. The pendulum mechanism, once released, uses gravity to propagate the slit, tearing the sample along the remaining length.
  3. The energy lost during this process is measured and used to calculate the sample’s average tearing force, yielding a reliable tear resistance value.
