Abstract (en)
[origin: WO2019197417A1] A heated aerosol-generating article (10)(110)(210) for use with an aerosol-generating device (310) having a heating element (320), the heated aerosol-generating article (10)(110)(210) comprising: a rod of aerosol-generating substrate (20); and a wrapper (60)(160)(260) at least partially circumscribing the rod of aerosol-generating substrate (20), the wrapper (60)(160)(260) comprising a heat control element (62)(162)(262) on at least one surface. The heat control element (62)(162)(262) comprises one or more circumferential bands (66)(166)(266) of a heat- shrinkable material, wherein upon heating of the heat-shrinkable material to a temperature above the shrink temperature thereof, the internal radius of each of the one of more circumferential bands of the heat-shrinkable material is reduced by at least 20 percent compared to the internal radius of the respective circumferential band prior to heating. As a result, the portion of the aerosol-generating substrate (20) underlying the heat control element (62)(162)(262) is deformed such that the resistance to draw (RTD) of the aerosol-generating article(10)(110)(210)is increased. The shrink temperature is between about 180 degrees Celsius and about 300 degrees Celsius.
