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.

We test the mechanical strength of seal seams on polyethylene pouches and sacks across a temperature range of -40 °C to +120 °C. To do this, we perform tensile tests on ten individual seam samples and compare their breaking force to that of the unsealed film material according to DIN 55543-3 and GKV standards.
The result is expressed as a percentage, indicating the seal efficiency relative to the film's base strength. This value allows you to verify the reliability of your packaging seals and ensures that the seams will withstand the mechanical stresses expected during transport and storage.
