Patent number: 7892475Abstract: It has been discovered that the properties of sheet or film materials of broad molecular weight distribution ethylene/propylene rubber impact-modified heterophasic copolymer (ICP) can be improved by blending the ICP with a second polyolefin. The second polyolefin may be a syndiotactic polypropylene (sPP), a random copolymer (RCP) of propylene and comonomer (e.g. ethylene and/or butene) made using a Ziegler-Natta or metallocene catalyst, medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), or low crystalline copolymer of propylene/?-olefin. Improvements include, but are not necessarily limited to, reduced motor amps, lower secant modulus, increased dart drop strength, increased gloss, reduced haze, increased elongation to yield, elimination of stress whitening, improved puncture resistance, and decreased seal initiation temperature. This sheet of film materials may be co-extruded with other resins or laminated with other materials after extrusion.Type: GrantFiled: October 7, 2008Date of Patent: February 22, 2011Assignee: Fina Technology, Inc.Inventors: Juan Jose Aguirre, Michael McLeod, Rodolfo Mier, Nguong van Nguyen

Publication number: 20100003494Abstract: An opaque polymer film is prepared by admixing high crystalline polypropylene with a microvoid causing filler and extruding to form a sheet that is then biaxially stretched to form an opaque film. End uses for these films include soda bottles, candy wrappers and synthetic paper.Type: ApplicationFiled: August 5, 2009Publication date: January 7, 2010Applicant: Fina Technology, Inc.Inventors: Juan Jose Aguirre, Mark Miller

Patent number: 6995213Abstract: Disclosed is a method of producing a novel biaxially oriented film having a high diffraction of light, and flexibility. In particular, the invention disclosed provides a method for making an opaque impact copolymer film by stretching in two dimensions an impact polypropylene copolymer. The invention is disclosed to be useful for making a material particularly suitable for a variety of applications including labeling media, food packaging and laminates. Also disclosed is a multilayer film having a first impact polypropylene copolymer layer and a second layer of another polymer wherein the multilayer film has significantly reduced haze. Also disclosed is film produced with a filler that has increased porosity and flexibility.Type: GrantFiled: September 29, 2003Date of Patent: February 7, 2006Assignee: Fina Technology, Inc.Inventors: Mark B.
