Tear resistance is one of the properties that make a plastic film strong. It proves to be crucial for its durability if the material is subjected to tear events. When testing a film's tensile strength, tensile modulus and tear resistance are often used in conjunction to provide a comprehensive picture of its strength. ASTM D1004 Test MethodThe mean force required to continue the tearing of an initial cut in a single sheet of paper is expressed as the internal tearing resistance. If the initial slit is made in the machine direction, the result is given as machine direction tearing resistance and similarly for the cross-machine direction (ISO 1974). Why measure tearing resistance?The tear resistance of a material, also called tensile strength at break, is the mechanical tensile stress at the exact moment of tearing and is also given in N/mm² or MPa. Since the maximum tensile stress and the tensile stress at the moment of rupture are usually identical for elastomers, the two terms are often used synonymously.
The measured results may be used to calculate the approximate tearing resistance of a single sheet. It is not suitable for single-ply tear testing. T 414 om-21.

Tear resistance is the measurement of a sample’s ability to resist tearing. Tear resistance can be impacted considerably by the speed of the test, e.g. test speed used in generate the tear. Tear propagation resistance for the purpose of acceptance testing is common with materials such as paper and rubber.L&W Tearing Tester measures tearing resistance according to the Elmendorf method. An initial cut is made in a test piece, which is then torn out of plane through a given distance using a pendulum. The work done in tearing the test piece is measured as .
