There is provided a multi-segment component for an aerosol generating article, the multi-segment component including a combustible heat source having at least one shaped recess on an outer surface thereof; an aerosol-forming substrate downstream of the combustible heat source; a wrapper circumscribing the combustible heat source along at least part of a length of the combustible heat source; and an inorganic glue located between the combustible heat source and the wrapper, the inorganic glue at least partially filling the at least one shaped recess.

A packaging or wrapping for a food product, capable of resisting to high temperatures and of eliminating the overpressure generated by the water vapour inside the packaging due to temperature rise, without the same packaging having any aperture communicating its inside and the outside environment. The packaging is also adapted to restrain/reduce the emission of odor-generating substances that are generated during the heating or baking of the packaged food product, with respect to what occurs in the absence of a packaging, or with a packaging provided with apertures.

The present invention relates to an inorganic adhesive composition and to a hermetic sealing method, and more specifically relates to an inorganic adhesive composition with which an organic solvent is not used and to a hermetic sealing method using same. To this end, the present invention provides an inorganic adhesive composition comprising: between 20 and 80 parts by weight of a water glass diluted solution containing between 60 and 90 parts by weight of water glass (Na2SiO2); between 20 and 80 parts by weight of a refractory inorganic filler; and a black pigment.
