LDPE/LLDPE FILM EXTRUSION

    LDPE and LLDPE have unique rheological or melt flow properties. LLDPE is less shear sensitive because of its narrower molecular weight distribution and shorter chain branching. During a shearing process, such as extrusion, LLDPE remains more viscous and, therefore, harder to process than an LDPE of equivalent melt index . LDPE and LLDPE are  used mainly in film applications for both packaging and non-packaging applications.
