ASTM D3354 Blocking Force Testing for Plastic Films
To find out how much two layers of polyethene film stick together, the ASTM D 3354 standard test method figures out the blocking load in grams that is needed to separate them with a 100 cm2 contact area. Rather than assessing blocking susceptibility, it offers quantitative data on adhesion strength.
