Abstract

The invention discloses red fiber coated white card paper which comprises a raw paper layer and a coating layer, wherein the raw paper layer comprises a surface paper layer, a core paper layer and a bottom paper layer which are sequentially superposed from top to bottom; and red fibers which account for 0.3-0.5% (in percentage by weight) of the core paper layer are distributed in the core paper layer. Besides, the coated white card paper further comprises a back coating layer coated on the bottom of the raw paper layer. A production process for the white card paper comprises the following steps of: separately filtering slurry of the surface paper layer, the core paper layer and the bottom paper layer, and compounding, squeezing, drying and carrying out surface sizing to obtain the raw paper layer; and then, sequentially applying a pre-coating layer, the core coating layer and the surface coating layer on the top surface of the raw paper layer. According to the red fiber coated white card paper and the production process thereof disclosed by the invention, red fibers which account for 0.3-0.5% of the core paper layer are uniformly embedded into the core paper layer to form a special anti-fake mark, so that good anti-fake effect is achieved; and one back coating layer is coated on the back surface of the raw paper layer as a blocking coating, so that the paper has a high blocking function on vapor, oxygen gas, fragrance and the like.

Description

technical field [0001] The invention relates to a white cardboard and a manufacturing method thereof, in particular to a red fiber-coated white cardboard with moisturizing and fragrance-preserving functions used for cigarette packaging and a corresponding production process thereof, belonging to the technical field of papermaking. Background technique [0002] At present, the packaging of high-end cigarettes is mainly in the form of aluminized cardboard or with aluminized lining paper to achieve the purpose of blocking water vapor, aroma and oxygen, retaining the taste of tobacco, prolonging the shelf life of products and improving product quality. However, this type of packaging material has the defects of poor bending resistance, pinholes or cracks are easily produced after bending, which affects the gas barrier and moisture barrier properties of the material, and the packaging waste of this type of material is difficult to recycle or degrade . Furthermore, the production...
