Composition of lldpe and uhmw-pe for film production
A recently granted patent (Publication Number: US11952480B2) discloses a composition for film production comprising a blend of linear low-density polyethylene (LLDPE) and high-density linear ultra-high molecular weight polyethylene (UHMW-PE). The LLDPE component, constituting about 99.5 wt % to 99.75 wt % of the composition, is characterized by specific physical properties such as density, melt index, and melt strength. The UHMW-PE component, making up about 0.25 wt % to 0.5 wt % of the composition, possesses distinct properties including molecular weight and density. When formed into a film, the composition exhibits desirable characteristics such as shear thinning index, strain hardening ratio, Elmendorf Tear, and Dart Drop values, meeting industry standards for film quality.
Furthermore, the patent claims encompass variations in the comonomers present in the UHMW-PE component, with specific ranges and types specified. The film produced from this composition is expected to have a thickness of at least 75 µm and additional properties like tear resistance and orientation values within defined ranges. The method of making the composition involves blending the LLDPE and UHMW-PE components in specified proportions to achieve the desired film properties. Overall, the patented composition and film manufacturing process aim to provide films with superior mechanical properties suitable for various applications in industries requiring high-performance packaging materials.
