Abstract: A sheet-form packaging material for forming a tobacco product package that packages a tobacco product in a tightly sealed internal housing part includes a paper base layer containing a fiber cellulose-based material; a steam barrier layer layered over the paper base layer, containing a resin material, containing no metal material, and having steam barrier property; and a heat-seal layer formed as an outer layer on at least one surface side of the packaging material, and coated with a heat-seal agent for heat-sealing against one another the edge portions of the packaging material. The steam barrier layer has a steam permeability of between 1 [g/m2·24 h] and 100 [g/m2·24 h] inclusive, and the heat seal layer has a thickness of between 0.5 [μm] and 5 [μm] inclusive.

Abstract: Provided are a wrapping material and package that are for commercial tobacco products, that are capable of tightly sealing commercial tobacco products, and that are environmentally friendlier than conventional materials and packages because of using less amount of resin materials. This sheet-shaped wrapping material is for forming a package that is for commercial tobacco products and that wraps the commercial tobacco products in a tightly-sealed internal containing portion. The wrapping material comprises: a paper base layer containing a fibrous cellulose material; an aluminum-containing layer that is layered on top of the paper base layer; and a heat seal layer that is formed as an outer layer on at least one side of the wrapping material, and that is a coating of a heat-sealing agent that heat-seals edges of the wrapping material together. The thickness of the heat seal layer is 0.5-5 μm.
