FIRE- RETARDANT, FIRE-RETARDANT BANDED CIGARETTE PAPER, AND MANUFACTURING METHOD FOR SAME |
摘要 |
The present invention applies to a fire-retardant, a fire-retardant banded cigarette paper, and a manufacturing method for same, wherein the retardant contains 10 to 30% of film-forming material by weight, 10 to 30% of filler material by weight, and 40 to 80% of solvent by weight. At least one band of fire-retardant is applied on the front or back side of the cigarette paper by means of printing to form a fire-retardant band having a width of 2 to 8 mm. The present invention relates to the technical field of manufacturing fire-retardant banded cigarettes, and reduces the air permeability of the strip coating section whereon the fire-retardant band is applied, said section being printed onto the base paper of the cigarette paper and having a fixed spacing. When the cigarette naturally burns to the fire-retardant section, the fire-retardant band absorbs heat and reduces the amount of oxygen which can enter, thereby causing the cigarette to extinguish. If the cigarette is smoked after having reached the fire-retardant band, the cigarette is supplied with oxygen and continues to burn. |
