Q

Metallocene linear low density polyethylene blown film poor transparency（Variant: Startup Commissioning Scenario）

A

Poor transparency is caused by high crystallinity or impurities, and needs improvement by increasing temperature, speeding up cooling and selecting suitable materials.Targeted preventive measures need to be taken in different production scenarios.
