Patent number: 10093780Abstract: Shrink film having a desirable balance of properties is manufactured from a polyethylene blend composition having a fractional melt index and a molecular weight distribution of from about 2.5 to about 7. The blend composition comprises a first blend component that is made with a single site catalyst and has a molecular weight of greater than about 140,000 and a first density, d1. The blend composition also contains a second blend component having a lower molecular weight and a second density, d2, that is greater than the density of d1 in an amount of from about 0.018 to about 0.032 g/cc. The films of this disclosure may be used, for example, as an overwrap or pallet wrap to protect goods during shipping and in food packaging applications (such as shrink wrap for frozen poultry).Type: GrantFiled: September 21, 2015Date of Patent: October 9, 2018Assignee: NOVA Chemicals (International) S.A.Inventors: XiaoChuan Wang, Peter Zoricak, Norman Dorien Joseph Aubee, Stephen John Brown

Patent number: 10066093Abstract: Barrier films are prepared from a blend of two high density polyethylene blend components and a high performance organic nucleating agent. The two high density polyethylene blend components have substantially different melt indices. Large reductions in the moisture vapor transmission rate of the film are observed in the presence of the nucleating agent when the melt indices of the two blend components have a ratio of greater than 10/1. The resulting barrier films are suitable for the preparation of packaging for dry foods such as crackers and breakfast cereals.Type: GrantFiled: November 14, 2017Date of Patent: September 4, 2018Assignee: NOVA Chemicals (International) S.A.Inventors: Norman Dorien Joseph Aubee, Douglas Checknita, P Scott Chisholm, Patrick Lam, Sarah Marshall, Denny Paul Sauvageau, Tony Tikuisis, Tingting Yu Chuang

Patent number: 9994004Abstract: A multilayer film is prepared from a high impact strength polyethylene (HI polyethylene); a Ziegler Natta catalyzed polyethylene (Z/N polyethylene) and a high pressure low density polyethylene (LD polyethylene) with i) at least one skin layer consists essentially of HI polyethylene and ii) at least one core layer comprises a blend of Z/N polyethylene and said LD polyethylene. The HI polyethylene has a density of from 0.915 to about 0.930 g/cc and a normalized impact strength of at least about 300 g/mil. The amount of HI polyethylene is from about 30 to about 55 weight % (based on the combined weights of the HI+Z/N+LD polyethylenes). The films described herein are readily prepared on blown film equipment and provide an excellent balance of mechanical properties.Type: GrantFiled: February 24, 2014Date of Patent: June 12, 2018Assignee: NOVA CHEMICALS (INTERNATIONAL) S.A.Inventors: Nitin Borse, Norman Dorien Joseph Aubee, P.

Patent number: 9109099Abstract: A new additive for plastics (for example, polyethylene) is prepared by reacting a fatty acid ester of glycerol (such as glycerol monostearate) with a source of a reactive divalent metal selected from zinc, calcium, and magnesium. In an embodiment, Zinc oxide is the reactive divalent metal and the reaction is conducted in the presence of an acid such as zinc acetate. In one embodiment, a molar excess of zinc oxide (compared to the fatty acid ester) is used. The additive is suitable for use in the preparation of injection molded parts, rotomolded parts, and films.Type: GrantFiled: December 19, 2014Date of Patent: August 18, 2015Assignee: NOVA Chemicals (International) S.A.Inventors: Owen Lightbody, Norman Dorien Joseph Aubee, P Scott Chisholm, Tony Tikuisis
