Aluminum-free anti-counterfeiting lining paper for cigarettes and production method thereof

The invention provides an aluminum-free anti-counterfeiting lining paper for cigarettes and a production method thereof. The lining paper is composed of an anti-counterfeiting paper layer, a coating layer and an aqueous printing oil layer. The technical indexes are as follows: the fixed quantify is 60+/-3 g/m ; the thickness is 0.07+/-0.005 mm; the flatness is more than or equal to 80 S; the tensile strength is more than or equal to 1.8 kN/m; the whiteness is more than or equal to 80%; the water content is 4-6%; and the air permeability is less than or equal to 0.01 micron/pa.s. The production method comprises the following steps of: firstly preparing a coating; and then, coating the prepared coating on front and back sides of anti-counterfeiting paper on a coating machine, so as to prepare a product. According to the production method, the anti-counterfeiting paper is used as basic paper and an anti-counterfeiting function is organically combined with the lining paper for the cigarettes, thereby achieving the anti-counterfeiting effect and greatly reducing the cost. The formula of the coating used in the preparation method is unique and a main paint part is papermaking porcelain clay which is widely applied to the papermaking industry and is low in price and an adhesive is polyvinyl alcohol and has no extraneous odor or toxicity; in the production process, no organic solvent is used and no pollutant is generated, thereby protecting environment. Non-ferrous metal such as aluminum foils, aluminum powder and copper powder, is not used, so that the product cost is low, the energy consumption is low, and ideals of energy saving and environmental protection and low-carbon lifestyle are realized.
