PURPOSE: A method for solidly and stably adhering PE (polyethylene) coating paper to the surface of corrugated paper by transferring a surface paper, i.e., PE coating paper one surface of which is coated with PE at ordinary or low temperature and forming the corrugated paper also at low temperature is provided. CONSTITUTION: The method is characterized in that corrugated paper (G) is formed by maintaining temperature of forming rollers (C,C') of an ordinary corrugated cardboard manufacturing apparatus to a low temperature of 100 to 150 deg.C, guiding rollers (E,E') are not heated, or the guiding roller (E') is heated to a low temperature of 100 to 150 deg.C so that the PE coating paper is adhered to the corrugated paper by adhesive since the PE coating paper is heated as a paper part of the PE coating paper is being transferred with being closely adhered to the guiding roller (E') in the process of transferring the PE coating paper with being closely adhered to the guiding rollers (E,E') in an 'S' character shape when the PE coating paper passes through the guiding rollers (E,E'), wherein the adhesive is prepared by mixing 25 to 35 wt.% of polysol, 45 to 50 wt.% of water, 15 to 25 wt.% of starch and 2 to 5 wt.% of borax.
