Abstract: A heat-shrinkable film which includes an ethylene-based polymer multilayer or monolayer film and a coating on an outer surface of the ethylene-based polymer film. The ethylene-based polymer film having a single layer or a multilayer structure formed from a first layer, a second layer, and at least one inner layer between the first and second layers. The coating including polyurethane which is the polymerized reaction product of: a polyol; and an aromatic isocyanate functional prepolymer. Further, a method of unitizing polymer wrapped primary packages is provided. The method includes wrapping one or more of the primary packages with the heat-shrinkable film with the coating disposed proximal the one or more primary packages and applying thermal energy to reduce the dimensions of the heat-shrinkable film to constrain the primary package within the heat-shrinkable film. The coating serving to alleviate sticking between the heat-shrinkable film and the polymer wrapped primary package.

Abstract: The present invention relates to a composition comprising an aqueous solution of a) a hydrophobically modified alkylene oxide polymer comprising a hydrophobic portion functionalized with a protonated secondary or tertiary amine or a quaternary ammonium salt and b) an acid and a salt thereof, which acid is phosphoric acid, nitrilotris(methylene)triphosphonic acid, hydrochloric acid, or sulfuric acid. The composition of the present invention is useful for the preparation of an associative thickener that can be stored for long periods, in the absence of ancillary biocides, without spoilage from biodeteriogenic attack.
