PURPOSE: A plastic corrugated cardboard is provided to improve the mechanical intensity and the aesthetic property by injecting an additive to a plastic material forming an upper board and a lower board. CONSTITUTION: An upper board(10) is prepared by injecting an upper board forming material into the upper side of a mold with a pre-set shape. A lower board(20) is prepared by injecting a lower board forming material into the lower side of the mold. A plurality of ribs(30) is integrated with the upper board and the lower board and spaces and supports the upper board and the lower board. Buffer holes are arranged between the ribs in order to alleviate impacts from the outside.
