(2) Good flexibility and bending resistance

Black core paper can withstand large bending, and can rebound and recover by itself. There will be no visible creases at the bends. In actual use, even after repeated shuffling operations, it can still maintain poker condition, good shape and excellent durability.

If it were replaced with an ordinary low-quality card, this degree of bending is likely to cause creases and powder drop, which will affect the appearance and service life.

(3) Good feel

The black core paper structure brings excellent hand feeling to the card. Some playing cards with a single-layer structure are too light and thin, lack flexibility and toughness, and are easily deformed and feel bad. Compared with these inferior cards, black core paper poker will obviously feel the feedback of card strength when held in the hand, they are very easy to stretch, and feel very heavy, without feeling thin.

Paper Core Identification

The price of a piece of 330gsm imported black core paper can reach 80.000-90.000 yuan. Due to such high prices, some counterfeit or counterfeit manufacturers started to produce counterfeit black core paper ideas.

In China, there are two general methods to produce counterfeit black core paper: one is to directly mix plain paper with black pulp; the other is to use pigment carbon black. The cost of both methods is much lower than that of producing real black core paper, but the paper effect cannot reach the level of black core paper.

The identification of paper with black layer can start from the following characteristics:

(1) The real black core paper will have an obvious three-layer structure after being torn; the fake black core paper will not have an obvious layered structure after being torn.

(2) The edges of playing cards with real black core paper structure will change color when exposed to water, and the inner layer of black core paper will leak out; fake black core paper cards will fade after contact with water.

(3) The real black core paper can withstand large bends and can be restored to its original shape; the fake black core paper is difficult to recover after being bent, and creases will appear.
