Blocking test/blocking strength

Testing the blocking tendency of plane packaging materials, in dependence on temperature T [°C], pressure p [MPa] and time t [h]. The evaluation is carried out either by manual test or by determining of blocking force Fmax [N] in a shear test using a tensile tester. If the sample is to be tested under several conditions, please create the test accordingly several times with the respective parameter settings.

Test Method Group: Mechanical properties

Norms:
  • DIN 53366 (2007-10) Testing of plastic films and sheetings – Determination of blocking strength

Required Sample Amount: Sample over total width of material, minimum length: 3 m
