Publication number: 20170130040Abstract: 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: ApplicationFiled: January 19, 2017Publication date: May 11, 2017Applicant: 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

Publication number: 20160229995Abstract: Polyethylene is often stabilized with the combination of a primary antioxidant (such as a hindered phenol, a hydroxylamine or a lactone) and a secondary antioxidant (such as a phosphonite, a monophosphite, or a diphosphite). The diphosphite additives are not completely compatible with “linear” polyethylene. This results in “blooming” of the diphosphite to the surface of the finished polyethylene part or polyethylene film. The use of a preblend of ethylene vinyl alcohol (EVOH) and diphosphite mitigates this problem.Type: ApplicationFiled: April 14, 2016Publication date: August 11, 2016Applicant: NOVA Chemicals (International) S.A.Inventors: Tony Tikuisis, Kam Wah Ho, Nitin Borse

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
