Problems solved by technology

Materials such as aluminum foil backing paper have low strength and are prone to cracks after bending, which will affect their fragrance retention and moisturizing properties
Moreover, in the cigarette packaging operation process, it is necessary to increase the process of wrapping the inner lining paper, which increases the complexity of the packaging process and affects the efficiency of cigarette packaging.

Abstract

The invention provides a white cardboard. The white cardboard comprises a surface coating, a crude paper layer and a bottom coating which are successively arranged; the bottom coating is formed by paint; and the paint comprises carboxymethyl cellulose and / or polyvinyl alcohol, starch, esterified hemicellulose, acrylic-acrylonitrile copolymer, high-water-absorption resin and water. Compared with the prior art, the crude paper layer is provided with the bottom coating, on one hand, the carboxymethyl cellulose and / or polyvinyl alcohol, starch and esterified hemicelluloses in the coating are usedto form a high-strength closed biological film to insulate the air, so that the cigarette pollution and fragrance attenuation can be prevented; meanwhile, by using the high water storage capacity of the high-water-absorption resin, the internal humidity in a cigarette box can be kept relatively stable; and the white cardboard is used as the white cardboard for packaging the cigarettes, the problems that the existing cigarette packaging white cardboard cannot effectively maintain the fragrance and humidity and additional aluminum foil lining paper is needed can be solved.

Description

technical field [0001] The invention belongs to the technical field of papermaking, in particular to a coating and white cardboard. Background technique [0002] At present, the white cardboard used for cigarette packaging on the market has two functions in cigarette packaging: one is to use the front side of the white cardboard to print various exquisite patterns to stimulate consumers' willingness to buy; the other is to use the white cardboard's high After being folded into a box, it can protect the appearance quality of the content cigarette rolls. However, another protection is needed in cigarette packaging, that is, to keep fragrance and moisturize, and to protect the mouthfeel and taste quality of cigarettes. At present, this protection is realized by adding aluminum foil backing paper inside the white cardboard cigarette box. Materials such as aluminum foil backing paper have low strength and are prone to cracks after bending, which will affect their fragrance and ...
