Description

A highly air-permeable tipping paper base paper with flame-retardant effect and preparation method thereof

technical field

The invention relates to the technical field of cigarettes, in particular to a highly air-permeable tipping paper base paper with a flame-retardant effect and a preparation method thereof.

Background technique

Cigarette tipping paper plays the role of connecting tobacco and filter. Utilizing the air permeability of tipping paper to dilute smoke is an important means to reduce harmful substances in cigarette smoke, which includes two methods of perforated tipping paper and natural air-permeable tipping paper. Perforated tipping paper refers to a technology that uses static electricity or laser to punch many small holes on the self-impermeable tipping paper to make it breathable. It is widely used abroad because of its simple method. However, because the small holes visible to the naked eye affect the appearance of cigarettes, many Chinese consumers do not accept perforated diluted cigarettes very well, so only a small amount of them are used in China.

With the country's emphasis on fire safety issues and the improvement of people's own safety awareness, the cigarette industry needs to strengthen the safety of cigarette products and reduce the fire safety hazards of cigarette products. At the same time, it is aimed at the international public health treaty " The Framework Convention on Tobacco Control and the State Tobacco Monopoly Administration's "Opinions on Strengthening the Management of Cigarette Packaging" curb excessive packaging, promote economical and clean production, and advocate the use of environmentally friendly and degradable products. The demand for healthy, safe and environmentally friendly products has become a new trend. development trend.
