Description

Inner clamping paper for cigarettes Technical Field The utility model relates to the field of cigarette packaging paper, in particular to inner clamping paper for cigarettes. Background The inner paper is a paper sheet which is arranged between the inner lining paper in the cigarette case and the outer shell paper of the cigarette case and has the functions of fixing the shape and supporting the cigarettes, and is an indispensable part of the hard-case cigarette package. Most of the existing inner paper is of a single-layer or simple multi-layer structure, when the cigarettes are impacted, vibrated or extruded by the outside, the inner paper cannot effectively disperse and absorb the external forces, so that most of impact force is directly borne by cigarettes, further the problems of breakage of filter tips, loose tobacco shreds and the like are easily caused, the appearance and quality of the cigarettes are affected, and when the cigarettes are opened, larger noise is generated due to friction between the inner paper and the cigarettes or other parts of the cigarettes, and the use experience of users is affected. How to invent an inner paper for cigarettes to solve the problems becomes a problem to be solved urgently by the person skilled in the art. Disclosure of utility model In order to overcome the defects, the utility model provides inner paper for cigarettes, which aims to solve the problems in the background. The utility model is realized in the following way: The utility model provides inner paper for cigarettes, which comprises an inner paper body, wherein the inner paper body comprises an inner liner layer, a buffer layer, a substrate layer and an outer protective layer, the inner liner layer, the buffer layer, the substrate layer and the outer protective layer are sequentially distributed from inside to outside, adjacent layers of the inner liner layer, the buffer layer, the substrate layer and the outer protective layer are fixed through hot pressing or adhesives, a damping ventilation assembly is arranged in the buffer layer, the damping ventilation assembly comprises a plurality of buffer cavities formed in one side of the buffer layer and a plurality of air guide channels formed in the buffer layer, a baffle plate is arranged on one side of the buffer layer far away from the buffer cavities, a buffer table is fixedly arranged on the side wall of the baffle plate corresponding to the buffer cavities, and the air guide channels penetrate through the upper side wall and the lower side wall of the buffer layer at the end parts of the buffer cavities in the same row. Preferably, the buffer cavity is arranged in a manner of being narrow outside and wide inside, and the section of the buffer cavity is arranged in a horn mouth shape. Preferably, a gap exists between the buffer table and the side wall of the buffer cavity, and a gap exists between the port of the air guide channel and the buffer table. Preferably, the buffer layer and the baffle are both foamed polyethylene films, and the buffer table is a silica gel sheet. Preferably, the inner liner is food-grade silica gel coated paper subjected to silver ion antibacterial treatment. Preferably, the outer protective layer is a high-density polyethylene microporous membrane, and the surface of the outer protective layer is coated with a hydrophobic nano coating. The beneficial effects of the utility model are as follows: The foam polyethylene film of the buffer layer, the buffer cavity with the narrow outer and wide inner and the silica gel buffer table form a multistage buffer system, when the buffer system is transported and stored, the buffer cavity absorbs dispersion pressure under the impact of external force, the buffer table deforms and buffers to avoid breakage of a filter tip and loosening of tobacco shreds, the high-density polyethylene microporous film of the outer protective layer is matched with the hydrophobic nano coating to effectively block water vapor and oxygen and prevent cigarettes from being damped and oxidized, the stable quality is ensured, the buffer layer is combined with the base layer, the hardness and softness are combined, the cigarettes can be firmly fixed, excessive extrusion is avoided, friction noise can be reduced by the buffer layer when the cigarette case is closed, and better use experience is brought. The food-grade silica gel coated paper with the silver ion antibacterial treatment on the inner liner layer inhibits bacterial growth, keeps the interior of the cigarette clean, simultaneously, has good flexibility, is tightly attached to the cigarette, avoids scratch and pollution when being taken out, the outer protective layer strongly blocks external moisture, the microporous structure of the substrate layer and the inner liner layer allows micro air to circulate, the buffer layer reduces the influence of humidity fluctuation, and the three are matched to form an 'external prevention and internal regulation'
