A package coating is processed by applying a plurality of aqueous mixtures over a substrate. The aqueous mixtures each include a combination of pigments and binders. A packaging article is also disclosed that is made from the package coating on a substrate. Additionally, a packaging system is included that contains commercial product.
Claims27
A process comprising:
- forming a first mixture over a substrate, wherein first mixture includes a first mixture first fluid content, and that includes from about 75% to about 82% inorganics and the balance organics;
- lowering the first mixture first fluid content to a first mixture second fluid content;
- forming a second mixture over the first mixture, wherein the second mixture includes a second mixture first fluid content, and that includes from about 70% to about 86% inorganics and the balance organics;
- lowering the second mixture first fluid content to a second mixture second fluid content;
- and
- forming a finish film over the second mixture.

A packaging article comprising:
- a substrate including a first side thereof;
- a brightener first film above the substrate, wherein the brightener first film includes calcium carbonate in a first amount, and brightener particles in a second amount, wherein the first amount is more than the second amount, and wherein the brightener first film includes at least one binder;
- a brightener second film above the first brightener film, wherein the brightener second film includes calcium carbonate in a third amount, and brightener particles in a fourth amount, wherein the fourth amount is more than the third amount, and wherein the brightener second film includes at least one binder;
- and
- a finish third film above the brightener second film.
2 more elements
A packaging system comprising:
- a folded and bonded substrate including first outer surface and a second inner surface, wherein the substrate includes a first side thereof;
- a brightener first film above the substrate, wherein the brightener first film includes calcium carbonate in a first amount, and brightener particles in a second amount, wherein the first amount is more than the second amount, and wherein the brightener first film includes at least one binder;
- optionally, a brightener second film above the first brightener film, wherein the brightener second film includes calcium carbonate in a third amount, and brightener particles in a fourth amount, wherein the fourth amount is more than the third amount, and wherein the brightener second film includes at least one binder;
- a finish third film above the brightener first film;
- and
- a commercial product disposed within the folded and bonded substrate.
