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.

A method of manufacturing a component for an aerosol-generating article including a taggant is provided, the method including the steps of: applying the taggant to the component; detecting an amount of the taggant that the component comprises; determining whether the detected amount of the taggant is less than a first-predetermined amount; and rejecting the component when the detected amount of the taggant is less than the first-predetermined amount. An apparatus for manufacturing a component for an aerosol-generating article including a taggant is also provided. A kit of parts is also provided.

According to an embodiment of the present disclosure, there is provided a smoking article including a smoking material portion which is wrapped with a smoking material wrapper, a filter portion which has an upstream end combined with the smoking material portion and is wrapped with a filter wrapper, and a tipping paper which is wrapped around at least a partial region of the smoking material portion and the filter portion so that the smoking material portion and the filter portion are combined, wherein the tipping paper is coated with an overprint (OP) coating solution in which at least one functional material and an OP auxiliary agent which enhances the solubility of the at least one functional material are added to an OP ink.

An embodiment of the present disclosure provides a smoking article including a smoking material portion which is wrapped with a smoking material wrapper, a filter portion which has an upstream end combined with the smoking material portion and is wrapped with a filter wrapper, and a tipping paper which wraps around the filter portion and at least a portion of the smoking material portion so that the smoking material portion and the filter portion are combined, wherein a design printing layer, an overprint (OP) coating layer, and a sweetener coating layer are disposed on a surface of the tipping paper.

An embodiment of the present invention provides a tipping paper for smoking articles. The tipping paper includes a fragrance carrier including a fragrance material and a carrier material, the carrier material includes the fragrance material, and the fragrance material included in the carrier material is disseminated from the tipping paper in response to moisture, saliva, or friction, and the carrier material is a material soluble in ethanol.

A tipping wrapper for aerosol generating articles has a base layer with a porosity of less than 1.5 C.U., wherein the base layer contains at least one filler material, the tipping wrapper further including a surface which is pigmented with a pigment component which contains CaCO.sub.3 and at least a second component serving as a non-combustible filler, the pigment component having a grammage of at least 2.0 gsm, wherein the pigmented surface has a surface smoothness of at least 400 sec. A method for producing a tipping wrapper for cigarettes includes providing a base layer of the tipping wrapper, and coating the base layer with a solution containing a filler component, wherein the coated base layer is pressed and heated at a predefined temperature which is greater than 100° C.

Green smoking tips and methods of mass manufacturing of green smoking tips comprising extracting volatile compounds and carbonizing hollow plant stem cuts.

A method of manufacturing a smoking article that contains, as members, at least a tobacco rod, a cooling segment, and a filter segment and in which a low-stiffness member L and a high-stiffness member H are adjacent to each other, the method includes (A) placing an adhesive on either surface of a tipping paper to form each portion of a high adhesive weight and a low adhesive weight per unit area after solidification, where the portion of a high adhesive weight is provided in a region for wrapping the member L; and (B) preparing a composite segment that contains at least the tobacco rod, the cooling segment, and the filter segment and wrapping the composite segment in the tipping paper.
