Abstract : The investigations were conducted on films of crystalline low density polyethylene (PE n.p.) and amorphous polyvinyl chloride (PVC). The durability of welded joints was determined on a special device, at a temperature of from 20-70C. The tests were conducted in a regime of constant stress on the test object, which was in the form of a belt with a width of 10 mm. The conditions of the experiment varied in such a way that the durability changed by 5-6 orders of magnitude. Equations were devised by which mechanical durability could be predicted.
