Tests of this standard
Sealing and welding properties of films, verification and comparison by laboratory sealing pressProduction of sealing or welding seams on our laboratory sealing press (Kopp) and testing of the sealing seams with the Zwick tensile testing machine. The seals are made using previously 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 depending on sealing pressure ps [N/cm] or sealing time ts [s]. Typically, a parameter is varied over 5 equal levels and the results are plotted graphically as a function of the variables (accredited test).
Seal strength, tensile test on strips (temperature range -40 to +120 °C)
Seal strength of machine-made sealings from pouches, sacks, packages, lidding films sealed on trays, cups etc. or sealing samples according DIN 55529 or ASTM F 88 (1 inch or 15 mm wide specimen), DIN EN 868 part 5 appendix D of medical packagings inclusive description of appearance of fracture.
Seal seam quality of PE- pouches or sacks (temperature range -40 to +120 °C)
You send us in pouches, sacks or sealings made of polyethylene film. We determine the seal strength quality in [%] relative to film strength, according GKV-test and evaluation clause Leaf III or DIN 55543-3 per seal (e.g. bottom seam) n = 10 individual measurements to lot size 5000 pieces, additional measurements for larger lots optional. The strength of unsealed flim is measured and set in relation to the strength of the seal tested under identical conditions.
