The high-permeability filter plug wrap (high-permeability wrap for short) refers to a wrap with higher air permeability, and generally refers to a wrap with air permeability higher than 3000 CU. The cigarette filter tip adopts high-permeability forming paper to dilute smoke, so that the tar content of cigarettes is greatly reduced, and the tar and harm reducing effects are achieved.
The desired high permeability plug wrap needs to have a certain strength in addition to a high air permeability. In order to achieve higher air permeability, the high-permeability filter rod forming paper is low in basis weight, the beating degree of the used paper pulp is low, but the strength performance of the lower beating degree formed paper is poor, the strength is too low, paper breakage is easy to occur during paper machine production, the production efficiency is influenced, and the hair falling phenomenon is serious during filter rod processing, so that the strength of the paper needs to be increased by utilizing a reinforcing agent, and in order to achieve an ideal effect, the air permeability of the paper is not influenced while the reinforcing agent is required to be enhanced.
The dry strength agent commonly used in the paper making industry mainly comprises organic synthetic high molecular compounds and polysaccharide and derivatives thereof, such as PVA, oxidized starch and the like, and in consideration of the safety of the auxiliary agent for the tobacco products, the reinforcing agent of the paper matched with the cigarettes does not generally adopt the organic synthetic high molecular compounds, but mainly adopts polysaccharide substances.

The microbial polysaccharide is a biopolymer which is generated by microorganisms such as bacteria, fungi, blue algae and the like in a metabolic process and has a protection effect on the microorganisms, and the microbial polysaccharide has wide attention due to stable performance and high quality and high efficiency in recent years.
The invention provides a method for improving high-permeability plug wrap paper by utilizing microbial polysaccharide for the first time, and the method is used for preparing filter stick plug wrap paper with high air permeability and high strength so as to meet the production, processing and use requirements of the cigarette industry.

The third aspect of the invention discloses application of the high-permeability filter plug wrap paper in improving the air permeability of a cigarette filter.
The raw materials used in the preparation method are all food-grade products.
The invention has the beneficial effects that:
1. the invention uses the high-transparency filter stick forming paper enhanced by microbial polysaccharide for the first time. The microbial polysaccharide is one or more of pullulan polysaccharide (also called aureobasidium pullulans polysaccharide), glucan or alpha-cyclodextrin. Pullulan is a polymeric polysaccharide formed by repeatedly connecting glucose into maltotriose through alpha-1, 4-glycosidic bond combination, and other maltotriose through alpha-1, 6-glycosidic bond combination at two ends. Dextran is an oligosaccharide formed by polymerization of several glucose molecules, and has a branched structure.

The microbial polysaccharide structure contains more hydroxyl, and the microbial polysaccharide structure can be combined with the hydroxyl in the fiber to form a hydrogen bond after being added into paper, so that the strength of the paper is increased. The high-permeability filter rod wrapping paper enhanced by the microbial polysaccharide can provide the strength required by the wrapping paper on one hand, and can ensure that the wrapping paper has higher air permeability on the other hand.
2. According to the invention, softwood pulp with low beating degree is taken as a main raw material for papermaking, so that on one hand, the strength required by papermaking can be provided, and on the other hand, higher air permeability can be ensured. The coniferous wood yarn smooth pulp or viscose fiber is matched in the filter stick forming paper, so that the bulk and porosity of the paper can be improved, the air permeability is increased, and the high-air-permeability filter stick forming paper with the air permeability higher than 20000CU can be prepared.
