Poor folding endurance of films
Fenómeno do problema
Creases and breaks appear after repeated folding
Análise das causas
The molecular weight is too low, the film is too thick, and the orientation is too large
Solução
Select high molecular weight with melt index <10 and control the film thickness
Conclusão principal
Folding endurance is directly related to molecular weight and film thickness
