A method of imparting hydrophobic properties to a paper product that comprises providing a paper product; immersing said paper product into a metal ion solution; and drying the paper product.

The present method relates to a manufacturing process of container labels with heat transfer technology, wherein alphanumeric codes are sequentially applied over, between and/or under the layers of specific inks and varnishes which protect said area of eventual friction and wear to which they are subject during transportation, handling and productive tests.

A coated paperboard including a paperboard substrate having a first side and a second side, and a multilayer coating having two or more layers in contact with the first side of the paperboard substrate, the multilayer coating including a base coating in contact with the paperboard substrate, the base coating having a coat weight from 6 to 10 pounds per 3000 ft.sup.2, and a top coating forming the outermost layer of the multilayer coating, the top coating having a coat weight from 3 to 10 pounds per 3000 ft.sup.2, wherein the multilayer coating comprises binder and pigment, the binder comprising one or more synthetic polymer binders and one or more natural biodegradable binders, and wherein the coated paperboard has a caliper of at least 0.010.

A coated paperboard is disclosed which includes a printable coating containing substantially no fluorochemical or wax in which the coated paperboard is fully compostable as well as repulpable, and exhibits no tendency toward blocking. The coating may be a multiple layer coating.

A coated paperboard is disclosed which includes a barrier coating containing substantially no fluorochemical or wax, exhibiting good resistance to oil and grease, no tendency toward blocking, the coated paperboard being fully repulpable as well as compostable. The coated paperboard may further have a printable coating on a surface opposite from the barrier coating.
