Seal strength, tensile test on strips (temperature range - 40 up to +120 °C)
Seal or weld seam strength of machine-made seal seams on pouches, packages or seal samples (also peel, cold seal, reseal) according to DIN 55529 (15 mm strips), ASTM F 88 (1 inch or 15 mm strip width), DIN EN 868 Part 5 Annex D for medical packaging, included description of fracture pattern.


Sealing properties, verification and comparison by laboratory sealing press
Preparing of sealings on our laboratory sealing press (Kopp) and measuring the sealing strength with a Zwick tensile tester. The sealings are prepared by ​​using pre-agreed parameters. To create sealing curves individual parameters are varied, e.g. for determining the dependence of the sealing properties on the sealing temperature Ts [° C]. Of course, sealing curves can also determined as a function of sealing pressure ps [N / cm] or sealing time ts [s]. Typically, one parameter is varied over 5 equal steps and the results are plotted graphically as a function of the variable. (accredit testing)
