Poor folding endurance of films
Fenómeno del problema
Creases and breaks appear after repeated folding
Análisis de la causa
The molecular weight is too low, the film is too thick, and the orientation is too large
Solución
Select high molecular weight with melt index <10 and control the film thickness
Conclusión clave
Folding endurance is directly related to molecular weight and film thickness
