A paper (10) is disclosed, especially for use in the production of corrugated cardboard. The paper (10) is formed from at least two layers couched together and having different composition and it contains wastepaper fibers and grass fibers. The special feature of the paper is that a first layer of the paper (10) is formed as a support layer (11) and contains a maximum fraction of 30 wt. % of grass fibers, a second layer of the paper (10) forms a top layer (12) with a minimum fraction of 20 wt. % of grass fibers and a maximum fraction of 80 wt. % of wastepaper fibers, and the fraction of grass fibers in the top layer (12) is higher than the fraction of grass fibers in the support layer (11).
