Poor folding endurance of films
Problembeschreibung
Creases and breaks appear after repeated folding
Ursachenanalyse
The molecular weight is too low, the film is too thick, and the orientation is too large
Lösung
Select high molecular weight with melt index <10 and control the film thickness
Wichtigste Erkenntnis
Folding endurance is directly related to molecular weight and film thickness
