- 1. A coated paperboard container, comprising:
a paperboard substrate; and a heat sealable aqueous barrier coating on the paperboard substrate, wherein the coated paperboard container has a repulpability yield of 75% accepts or greater and a wet rigidity loss of 50% or less.
- 23. A coated paperboard container for holding hot beverages, comprising:
a sidewall comprising:
a sidewall paperboard substrate having an interior surface facing an interior of said container and an exterior surface facing an exterior of said container, an upper end, a lower end, a first longitudinal end, and a second longitudinal end; and
a first aqueous barrier coating on the interior surface of the sidewall paperboard substrate, wherein the first longitudinal end of the sidewall paperboard substrate is heat sealed, by way of the first aqueous barrier coating, to the second longitudinal end of the sidewall paperboard substrate to form a sidewall seam, wherein the coated paperboard container has a repulpability yield of 75% or greater, a side seam bond strength of 30 pounds per inch or greater, and a wet rigidity loss of 20% or less.
- 46. A coated paperboard container for holding cold beverages, comprising:
a sidewall comprising:
a sidewall paperboard substrate having an interior surface facing an interior of said container and an exterior surface facing an exterior of said container, an upper end, a lower end, a first longitudinal end, and a second longitudinal end;
a first aqueous barrier coating on the interior surface of the sidewall paperboard substrate; and a second aqueous barrier coating on the exterior surface of the sidewall paperboard substrate, wherein the first longitudinal end of the sidewall paperboard substrate is heat sealed, by way of at least one of the first aqueous barrier coating and the second aqueous barrier coating, to the second longitudinal end of the sidewall paperboard substrate to form a sidewall seam, wherein the coated paperboard container has a repulpability yield of 75% or greater, a side seam bond strength of 30 pounds per inch or greater, and a wet rigidity loss of 50% or less.
