  • Method of improving blown film processing performance and physical properties
    Patent number: 6930137
    Abstract: An improved method of manufacturing blown polyolefin films with increased bubble stability and higher blown film production rates is disclosed. A method in which the amounts and ratios of known antioxidant polymer film additives (phosphites and phenolics) are controlled to provide limited long chain branching (LCB) and greater rheological breadth in a polyethylene melt to improve both processing characteristics and mechanical properties in the resulting film.
    Type: Grant
    Filed: May 29, 2003
    Date of Patent: August 16, 2005
    Assignee: Fina Technology, Inc.
    Inventors: Michael McLeod, Nguong van Nguyen, Gerhard Guenther, Tim J. Coffy, Rodolfo Mier Martinez
