Latest Patents
Rongmei Liu holds a patent for a propylene polymer composition and the oriented film prepared from it. The invention provides a propylene polymer composition designed for producing a biaxially oriented film. This composition includes a propylene random copolymer and a propylene homopolymer. The propylene random copolymer is a copolymer of propylene and ethylene, and it may also include one or more alpha-olefins. The composition boasts an overall isotacticity index of 96.5% or higher and an ethylene content exceeding 0.3 wt %. Additionally, the melt flow rate of the propylene random copolymer is lower than that of the propylene homopolymer. The resulting biaxially oriented polypropylene film exhibits excellent physical properties, including higher modulus and stiffness without the need for stiffening agents. The production process is characterized by good film-forming stability and a high stretching speed.
