Two or two kinds of mixed pulps are used as core layer and bottom layer, and 100N bamboo pulp is developed, or 60%-70% bamboo pulp and straw pulp or waste paper pulp, or 20% wood pulp and cotton stalk pulp and kenaf stalk pulp are used to make kraft boards. Finally, Kraft boards are made by sizing and calendering, and then Kraft boards are made by sizing and calendering.
