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.

Test Method Group: Mechanical properties

Norms:

DIN 55543-3 (06-2010) Verpackungsprüfung – Prüfverfahren für Verpackungsfolien – Teil 3: Bestimmung der Festigkeit von Längsnähten an Säcken und Beuteln
DIN 55529 (2012-09) Packaging – Determining the sealed-seam strength of sealings made of flexible packaging material
