Many countries are now introducing new regulations to comply with the fire security and reduce the risk of the fire caused by cigarettes. For this reason the demand of Low Ignition Paper is constantly increasing. This paper contains rings that extinguish fire when reached. Porosity in the ring is zero so that, to maintain an overall porosity equal to normal cigarettes, customers are forced to increase porosity. Usually a 50 CU is substituted by a 70 CU.
Fire safe cigarettes, abbreviated “FSC”, also known as lower ignition propensity (LIP), reduced fire risk (RFR), self-extinguishing, fire-safe or reduced ignition propensity (RIP) cigarettes, are cigarettes that are designed to extinguish more quickly than standard cigarettes if ignored, with the intention of preventing accidental fires.
Fire safe cigarettes are produced by adding two to three thin bands of less-porous cigarette paper along the length of the cigarette, creating series of harder-to-burn ¡°speed bumps.¡±[1]?As the cigarette burns down, it will tend to be extinguished at each of these points unless the user is periodically intensifying the flame by inhaling.[1]?Contrary to myth, FSC cigarettes use no more?ethylene vinyl acetate?(EVA) adhesive than conventional cigarettes, and its use as an adhesive predates the introduction of FSC technology.[2]
According to quality characteristics, bobbin cigarette paper is divided into three types:
Class A is mainly used in high-speed cigarette machines to produce high-end cigarettes.
Class B is used for medium and high speed cigarette machines, mainly producing mid-range cigarettes.
Class C is used for low-speed cigarette machines, corresponding to low-grade cigarette production.
Cigarette paper length are generally: 4000m, 5000m, 6000m; its width are mainly three types: king size (26.5mm-27.5mm), medium size (20.5mm-22mm), super slim (17.5mm-19mm)
