Problem & Lösung

Q

Metallocene linear low density polyethylene film insufficient strength（Variant: Color/Material Change Scenario）

A

Insufficient film strength is caused by improper material selection or process parameters, requiring optimization from raw material, temperature and blow-up ratio.Targeted preventive measures need to be taken in different production scenarios.
