Abstract

A paper material is provided herein, wherein the paper material includes a fibrous material including at least 5 dry weight percent of fibers derived from a plant of the Nicotiana species; wherein the paper material has a basis weight ranging from about 5 g/m 2 to about 450 g/m 2 ; and wherein the paper material has a caliper ranging from about 0.01 mils to about 200 mils. The paper material can be suitable for use in a smoking article in the form of at least one of a tipping material, a plug wrap and a wrapping material. The paper material can be suitable for use in at least one of a soft carton container suitable to house smoking articles, a label, a paper substrate of a barrier layer, a hard carton suitable to house smoking articles and a container suitable to house smokeless tobacco products.
