Problems solved by technology

At present, the clay layer is often coated on the back of the inner lining paper. Due to the porous structure of the clay, it has a certain moisture absorption and desorption effect. However, this technology uses varnish to reconcile the paint, which leads to the coating being too closed, greatly reducing the humidity control effect, and increasing the coating. Cloth and Drying Process
PVDC is also used as the moisture-retaining coating material for cigarette inner lining paper. When the coating amount is 20g / ㎡, the moisture retention performance of PVDC is relatively closest to that of the conventional control aluminum lining paper, but this does not solve the problem of cigarettes. Continuous humidity effect after opening the package
PVDC is currently the most environmentally adaptable variety of plastic packaging materials. It can neither be degraded in the natural environment, nor can it be melted, recycled, and recycled. Incineration and landfills also produce hydrogen chloride and even dioxins. Under the background of restricting plastics and promoting green packaging, it obviously does not meet the development requirements
[0004] In addition, in the manufacture of the existing lining paper for cigarettes, there are references to the humidity-controlling paper technology used in construction, textiles, and cultural relics protection. The inorganic mineral humidity-controlling materials used are mainly concentrated in sepiolite, artificial zeolite, halloysite, Diatomite, montmorillonite, kaolin, etc. These inorganic minerals are mainly characterized by many internal pores, large specific surface area, and strong adsorption capacity, but their moisture absorption capacity is limited. Most of them need to be used in combination with other types of humidity control materials, but Composite technology generally has the disadvantages of complex preparation process and high cost
Humidity-conditioning paper mainly focuses on the humidity-conditioning effect, and less consideration is given to other properties of the paper, which cannot meet the packaging requirements

Abstract

The invention provides lining paper for cigarettes and a manufacturing method and application of the lining paper. The manufacturing method of the lining paper comprises the steps that bleached sulfate softwood pulp and bleached sulfate hardwood pulp serve as raw materials to be subjected to pulp grinding treatment; preparing a suspension with the solid content of 20-30% from the modified iron silicate and diatomite according to a certain proportion, adding the suspension into the ground paper pulp, adding a certain amount of an inorganic pigment solution, and uniformly mixing; diluting the slurry, adding AKD emulsion, and uniformly mixing; adding a dispersing agent and uniformly mixing; papermaking and forming; and after squeezing and drying, sequentially coiling and slitting the paper sheets to obtain the paper. The lining paper can be compounded with an aluminum foil to prepare the cigarette lining paper or a vacuum aluminized film is transferred on one side of the cigarette lining paper, has the functions of humidity regulation (two-way moisture regulation), moisture preservation and fragrance preservation, can prolong the shelf life of cigarettes stored in different climatic environments, and still has better effects of humidity regulation, moisture preservation and fragrance preservation after a package is opened. And the application range of the lining paper can be further expanded.

Description

technical field [0001] The invention relates to the technical field of manufacturing cigarette inner lining paper, in particular to a cigarette inner lining paper and a manufacturing method and application thereof. Background technique [0002] The moisture content of cigarettes is closely related to the sensory quality of cigarettes. my country's climate has a phenomenon of dryness in the south and the north, which leads to the problems of water loss and drying, or mildew and flavor loss, and the loss of flavor in cigarette products in different regions. The tobacco industry has also carried out a lot of research on improving the physical moisturizing performance of cigarettes, mainly focusing on the development and application of tobacco moisturizing agents. Through research, it is found that the barrier performance of cigarette packaging is the key to affecting the physical moisturizing performance of cigarettes. High-quality cigarettes The packaging materials and technol...
