Abstract
The rheological and mechanical properties of several LLDPE film grades with different structures were studied. It was shown that the rheological properties of the studied grades differ significantly in terms of effective viscosity and melt flow patterns under shear loads. The properties of films produced from the studied materials under identical conditions were compared. Film tear resistance is ambiguously related to the LLDPE structure. Films made from butene-containing LLDPE exhibit higher tear resistance values. Films made from butene-containing LLDPE have lower tensile strength values than films made from hexene-containing LLDPE. Orientation processes during film production significantly affect the film properties.
