Abstract (en)
[origin: WO2022002477A1] The invention relates to a wrap paper which is suitable for use on aerosol-generating articles and which comprises pulp fibres and a char-forming substance, the pulp fibres constituting at least 70% and at most 95% of the mass of the wrap paper and the char-forming substance being present in a concentration of at least 5% and at most 20% relative to the mass of the wrap paper and being present in the wrap paper in such a concentration that the quotient r = RT/R0, where R0 is the tensile strength measured according to ISO 1924-2:2008 under the conditions of ISO 187:1990 and RT is the tensile strength measured according to ISO 1924-2:2008 under the conditions of ISO 187:1990, is at least 0.20 and at most 0.90 after the wrap paper has been exposed to a temperature of 230°C for one minute.
