Under the heating conditions (muffle furnace temperature setting 230 ° C., paper sample heating time 3 minutes) in this embodiment, the actual paper temperature is about 230 ° C. which is the same as the muffle furnace set temperature at least 1 minute after closing the door.

Abstract

L'invention concerne un papier à rouler pour un article à fumer chauffé sans combustion qui comprend une section blanche dans laquelle le score de discrimination obtenu par substitution de valeurs de différence de couleur dans le système de couleur CIE Lab avant et après chauffage pendant trois minutes à 230 °C dans l'équation (1) est une valeur numérique inférieure à 0,62 et la blancheur ISO est d'au moins 83 %. (1) Score de discrimination (y) y = y=-0,18×ΔL*+0,08×Δa*+0,13×Δb*-2,36 (dans l'équation (1), les valeurs de différence de couleur dans le système de couleur CIE Lab avant et après le chauffage sont les valeurs pour L*, a* et b* avant chauffage soustraites des valeurs pour L*, a*, et b* après chauffage. ΔL* représente la différence de clarté L* après chauffage et avant chauffage du papier à rouler. Δa* représente la différence de couleur a* après chauffage et avant chauffage du papier à rouler. Δb* représente la différence de couleur b* après chauffage et avant chauffage du papier à rouler.)
