Abstract: A method of preparing a retort packaging article includes: includes applying an ink to an outer surface of a sealable packaging and overlaying a substantially transparent lamination layer over the ink to envelope at least a portion of the sealable packaging. The ink includes a binder that includes a polyurethane resin that contains an elastomer which is a reaction product of a polyol and polyalkylene glycol with an isocyanate. The elastomer may be chain extended with a diamine or a diol.

Abstract: A method of preparing a retort packaging article includes: providing a sealable packaging; applying an ink to an outer surface of the sealable packaging; and overlaying a substantially transparent lamination layer over the ink and enveloping at least a portion of the sealable packaging. The ink contains a styrene-acrylic resin, which has anhydride functionality, and a polyurethane resin.

Abstract: Described is an aqueous cold seal adhesive in the form of an aqueous polymer dispersion comprising a mixture of a first polymer and a second polymer, wherein the first polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of C1 to C20 alkyl (meth)acrylates and has a glass transition temperature of less than 0° C.; and wherein the second polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of vinylaromatics having up to 20 C atom, and has a glass transition temperature of at least 50° C. Also described are cold sealable coated polymer films coated with the aqueous cold seal adhesive and a method for producing a cold-sealed pack by applying the aqueous cold seal adhesive to a packaging substrate.
