This method is used to investigate the strength of the heat seal joints used for heat and self-sealable pouches, and reels for use as packaging of medical devices that are sterilized.
Free ends of the test specimen is supported between two clamping jaws and is pulled apart until failure at a constant rate of displacement. This test is to determine the peel characteristics of paper/plastic laminate products, as well as the strength of the heat seal joint for pouches and reel material. We use screw action grips, pneumatic action grips with rubber coated jaw faces for clamping of the material, which are fitted to a tensile testing machine - normally a Quasar 2.5 single-column or dual-column benchtop model. Graphwork allows you to input specimen details, set the desired test control, automatically calculate the desired results and statistics, and produce a test report all in accordance with this Standard.
