Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer.

Wrapping materials for smoking articles

Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer. For a representative wrapping material, a pattern of applied to the wire side major surface of the wrapping material substrate as a plurality of layers, and at least one of the layers includes ethylcellulose and calcium carbonate. For that layer, the calcium carbonate is present in an amount greater than the ethylcellulose, on a weight basis. The ethylcellulose and calcium carbonate typically are applied as part of a non-aqueous formulation incorporating iso-propyl acetate, triacetin and lecithin.

A high barrier sealable packaging material and a high barrier heat sealed package for smoking articles, such as cigarettes and the like, are disclosed. The packaging material comprises a base layer of a polymeric film, such as a biaxially oriented polyethylene terephthalate (PET) film which has been metallized on one surface thereof with a layer of metal, such as aluminum. The metallized film is then imprinted with ink with a design and/or printed matter on either the metallized or unmetallized surface. Subsequently to or concurrently with the printing, a heat seal layer is applied to the printed and/or unprinted surface for forming a heat seal about which the material is wrapped. In one embodiment, the high barrier packaging material is used as an overwrap for a cigarette package having a tear tape for removing one end of the overwrap. In another embodiment, the high barrier packaging material is used as an overwrap for a carton containing a plurality of cigarette packages and having a tear tape for removing one end of the carton overwrap.
