The present invention provides a method for printing high opacity images or coatings using solvent based inks comprising hollow polymeric microspheres, wherein the inks do not contain titanium dioxide. The International Agency for Research on Cancer (IARC) has classified titanium dioxide as “possibly carcinogenic to humans,” The method of the present invention allows one to avoid the use of inks that rely on titanium oxide for high opacity, which has become of importance for articles that come into contact with one's mouth, for example, cigarette tipping papers.

The present invention relates to a process for the manufacture of bobbins, of sheets and of a booklet of sheets of roll-your-own cigarette paper and to a process for the manufacture of a booklet of sheets of roll-your-own cigarette paper.

A wrapper for a smoking article has a base web and a plurality of elements each having at least a pair of patch areas where diffusivity is in the range of 0 to about 0.2 cm/sec. Patches of adjacent elements are circumferentially offset from one another along the axis of a smoking article. The add-on material can be applied by gravure printing in a single pass in a chevron pattern such that an apex of the element is co-linear with substantially symmetrically spaced points on a trailing, outer edge of an adjacent element. Testing elements may be simultaneously printed with the add-on material to monitor diffusivity and/or presence of add-on material.

The present invention relates to a sheet of roll-your-own cigarette paper comprising an adhesive strip, the grammage of which is less than 8 g/m.sup.2 and to the process for manufacturing such a paper.

The present invention relates to a vaping article comprising an aerosol-generating zone, a zone for cooling the aerosol comprising a paper in the shape of a hollow tube, this paper comprising a fibrous substrate, and optionally a filtering zone,
characterized in that the zone for cooling the aerosol is functionalized by a plant extract and an aerosol-generating agent.

A smoking article wrapper includes a non-perforated air permeable base paper having a naturally high porosity of 40-80 cm.sup.3/min air passing through a sample of 1 cm.sup.2 of this base paper at an applied pressure difference of 1 kPa, wherein the smoking article wrapper has at least one embossed surface area and at least one non-embossed surface area. The air permeability of the smoking article wrapper is such that it provides a mean volumetric flow rate of ≥40 cm.sup.3/min air passing through a sample of 1 cm.sup.2 of this smoking article wrapper at an applied pressure difference of 1 kPa. The embossed area includes an embossing having a depth of ≥16 μm. A smoking article including the smoking article wrapper and respective methods to produce such a smoking article wrapper and a smoking article are also provided.

A method of manufacturing a wrapper for an aerosol generating article includes applying an adhesive to one surface of a metal layer and attaching a first paper layer thereto, applying the adhesive to the other surface of the metal layer and attaching thereto a second paper layer different from the first paper layer, and drying the adhesive applied between the metal layer and the first paper layer and the adhesive applied between the metal layer and the second paper layer.

A non-sticking lip tipping paper is disclosed that includes a base paper, a color layer and a surface coating. The color layer is formed by printing and drying a color ink on the base paper; the surface coating includes a water-based glue and is coated thereon after drying the color layer. The water-based glue includes the following components by weight: 30-65 parts of a modified water-based resin solution, 10-20 parts of water, 8-15 parts of ethanol, and 5-12 parts of a water-based additive. The water-based additive is a mixture of a wax emulsion and magnesium silicate in a weight ratio of 1:5. A preparation method and a method of applying the non-sticking lip tipping paper are also disclosed.

The present disclosure provides an aerosol-generating article including an aerosol generator including: an aerosol generator comprising an aerosol-generating material configure to vaporize into an aerosol; a tobacco filling part comprising an inner wrapper on which a plurality of folds are formed, and granules of a tobacco material attached to the plurality of folds such that a tobacco component is added to the aerosol passing through the tobacco filling part; and a thermally conductive wrapper wrapped around at least part of outer surfaces of the aerosol generator and the tobacco filling part, and configured to transmit heat to the aerosol-generating material and the tobacco material.

The disclosure relates to delivery systems including aerosol-generating material and a cooling agent WS-3 in an amount sufficient to provide a cooling effect. In particular, the disclosure relates to delivery systems that do not provide any clearly noticeable smell or taste other than one of tobacco.
