This attachment is a specialized probe for peel testing used to evaluate the quality, strength, and adhesive strength of sealed packaging. The universal device of the physical property tester (physical property analyzer, texture analyzer) can adjust the direction of force application according to needs, and the test container is supported at different angles of 0o, 45o, and 90o. Use an adjustable plastic belt to fix containers of different sizes or shapes at the base position of the physical property tester (physical property analyzer, texture analyzer), and clamp the edge of the cover with a fixture to apply force upwards to test the peeling strength.
