Abstract:
     The invented method is used for forming the disposable paper tablware made of thin paper board of the coarse pulp of rice straw and wheat straw. The characteristic lies in that on the periphery of the board blank of the tableware several slots or triangular notches are made. When forming, the two sides of slots or notches are mutually overlapped and pressed together by pressure or sticked together by binder. The advantages are that the board blank does not crease, break and crack when forming and the yield is high and cost is low.
