Non Destructive Seal Testing Polymeric Tray
Abstract
Seal strength measurements and analyses of flexible and semi-ridged containers are usually done by destructive methods. At present, there is no method capable of quantifying or assessing the seal (e.g. tack, creep) strength non-destructively. This project developed a prototype non-destructive (ND) test system for the polymeric half steam table tray as a replacement for the traditional internal pressure tester. The ND tester is based on a static compression force that reduces the volume of the tray and creates an internal pressure inside the tray and exposes the seal to forces that open the seal if the seal strength is non-fusion. Compared to the traditional internal pressure test protocol, a higher seal quality will be required to pass the ND tester. The ND test methodology was also used to evaluate the effects of seal anomalies. It was determined that trays with visual defects can be evaluated in the ND tester and classify the defect appropriately as critical, major, minor and none score-able, based on the outcome of this test.
