A paperboard structure that includes a paperboard substrate which includes a first major side and a second major side along with at least one barrier coating layer on the first major side. The barrier coating layer(s) may include a binder and a pigment, wherein the binder has a glass transition temperature of at least 20° C., wherein a ratio of the binder to the pigment is at least about 1:2 by weight.

Paperboard structure with at least one barrier coating layer

A cellulosic structure including a cellulosic substrate comprising a first major side and a second major side opposed from the first major side, an oil barrier layer on the second major side of the cellulosic substrate, and a water barrier layer on the second major side of the cellulosic substrate, wherein the oil barrier layer is positioned between the cellulosic substrate and the water barrier layer.

Coffee stain-resistant cellulosic structures and associated containers and methods
