Applications

Low melt flow (high viscosity) grades are used in blown films for bags and construction, extruded sheeting and pipe, and blow molded containers such as squeeze bottles. Linear Low Density (LLDPE) resins exhibit higher strength and stiffness than traditional LDPE resins for many of these same applications.
