Packaging testing – tensile strength

How we test the strength of seals and of packaging materials – both important in product protection and safety assurance. The test is used by food manufacturers to troubleshoot seal failure problems and to investigate seal integrity versus opening strength.

A tensile test provides information about a material strength including elongation, yield point and tensile strength. The material sample is cut using a template and the size is dependent on the standard being used. This test shows the strength of a seal. The sample is placed between two jaws and the upper jaw moves away from the lower jaw pulling the seal apart. The graph generated is related to the seal profile and different seal profiles will produce a different graph. The data collected and plotted on the graph is related to the force required to pull the seal apart. The test ends when the seal has been broken. This test can also be used for measuring the tensile strength of other materials, in this instance paper, and the force required to rupture a strip of paper. Again, the upper jaw moves away from the lower jaw and the force required to rupture the paper is recorded. Not all materials will rupture under this force but the equipment can be set up for greater forces in order to measure the force required to rupture thicker pieces of materials. This test would be used by packaging users, for example food manufacturers, for investigations into seal failures and to investigate seal integrity versus opening strength.
