Specifically, this invention relates to crystalline propylene polymers comprising both propylene homopolymer and propylene copolymer. The compositions are prepared using metallocene catalyst systems comprising at least two metallocenes in a polymerization process that involves the sequential or parallel polymerization of propylene homopolymer and copolymer using propylene with a small amount of comonomer, preferably ethylene. The polymerization is catalyzed by a dual metallocene catalyst system. The resulting polymers have a broad, bimodal molecular weight distribution. The resulting polymers are excellent for use in the production of biaxially oriented films or non-oriented films.Type: GrantFiled: March 6, 2001Date of Patent: June 10, 2003Assignee: ExxonMobil Chemical Patents Inc.Inventors: Aspy K. Mehta, Michael C. Chen, James J. McAlpin, Anthony N. Speca, Kelly Tormaschy, Chon Y. Lin

Patent number: 6562905Abstract: The present invention concerns a bimodal film-making HDPE composition, a process for the preparation thereof, a film prepared thereof and a film-making process. The composition comprises at least one polyethylene component having a relatively low molecular weight and another polyethylene component having a relatively high molecular weight. The composition has a shear thinning index defined by the relationship: SHI5/300≦0.00014 &eegr;5kPa+78 wherein &eegr;5kPa is the complex viscosity at G*=5 Pa and SHI5/300 is the ratio of complex viscosity at G*=5 kPa to the complex viscosity at G*=300 kPa. By means of the invention it is possible to produce material for making HDPE blown films with good mechanical properties in a process where the whole range of PE products from LLD to HD can be produced.Type: GrantFiled: November 9, 2000Date of Patent: May 13, 2003Assignee: Borealis Technology OyInventors: Auli Nummila-Pakarinen, Ole Jan Myhre, Jarmo Lindroos, Solveig Johansson

Patent number: 6534138Abstract: The invention pertains to a method for the manufacture of a packaging material (1; 21) for the production of packaging blanks and packages and comprising the steps of providing at least on surface layer (2, 2′; 22, 22′) in the form of a continuous material web and substantially consisting of cellulosic fibres and applying a distance layer (3; 23) comprising a matrix material and reinforcement fibres thereto so that said surface layer (2, 2′; 22, 22′) is bonded to said distance layer (3; 23). The matrix material in the distance layer (3; 23) is in an expandable state when it is applied to the surface layer (2, 2′; 22, 22′) and is expanded in a separate process step, subsequent to the application step. The invention also concerns expandable packaging materials.Type: GrantFiled: March 6, 2001Date of Patent: March 18, 2003Assignee: SCA Packaging Marketing NVInventors: Alf Jonasson, Jeff Thornton

Patent number: 6472033Abstract: The present invention relates to an airbag cushion which exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a panel together) in correlation to an overall high amount of available inflation airspace within the cushion itself. These correlated elements are now combined for the first time in what is defined as an effective seam usage index (being the quotient of the length of overall seams on the cushions and the available inflation airspace volume). The inventive cushion must have at least one substantially straight seam and must possess an effective seam usage factor of less than about 0.11. A cushion exhibiting such a low seam usage factor and also comprising an integrated looped pocket for the disposition of an inflator can is also provided as well as an overall vehicle restraint system comprising the inventive airbag cushion.Type: GrantFiled: July 30, 1999Date of Patent: October 29, 2002Assignee: Milliken & CompanyInventor: Ramesh Keshavaraj
