Abstract
The invention provides a playing card paperboard, comprising a surface layer, a surface lining layer, a core layer, a bottom lining layer and a bottom layer, which are sequentially arranged. The playing card paperboard is characterized in that the core layer is formed by a fiber layer comprising water-soluble fibers and powered rubber filler and having holes, wherein the holes are uniformly distributed to form a spatial net structure and have irregular shapes; the total area of the holes is 1/3 to 3/4 of the fiber layer total area; and the area of each hole is not lager than 16 mm<2>. The adhesive spraying process among the core layer, the surface lining layer and the bottom lining layer is reduced; the interlayer bonding force between the core layer and the paper pages on the two sides can be increased; the tensile strength, the deflection and the folding strength of the core layer and the playing card paperboard are greatly improved; the use amount of the core layer fibers is reduced; meanwhile, the elasticity and hand feeling of the playing card paperboard are enhanced; and the adoption of the colorful powered rubber filler can increase the optical opacity of the playing card paperboard.
