Description

technical field

[0001] The invention belongs to the technical field of filter stick paper preparation, and in particular relates to a method for making filter stick paper by using PLA fibers in a wet process. Background technique

[0002] With the improvement of living standards, more and more people pay attention to the health problems of smoking. Heat-not-burn is currently a globally recognized healthy way of smoking. Heat-not-burn technology heats the cigarette just enough to deliver the flavor without igniting the cigarette. Normally, when ordinary cigarettes are ignited and smoked at a high temperature of 500-900°C, many harmful substances will be produced. However, heat-not-burn technology can control the temperature, greatly reducing harmful substances, and at the same time meeting the individual needs of young people. However, because shredded tobacco used in heat-not-burn cigarettes is different from ordinary cigarettes, it does not participate in combustion, the ...
