A paper cup cover and a preparation method therefor. The paper cup cover comprises a hollow paper cup cover body (1) and a round paper cup plate (2). A round edge of the paper cup cover body (1) located on the bottom is rolled in the shape of an arc from bottom to top to form an arc-shaped roll. An upper end of the arc-shaped roll is flattened to form a flat annular connecting surface (3). The connecting surface (3) is press-fitted to and fixed with a flat edge of the paper cup plate (2). The preparation method for the paper cup cover comprises corresponding rolling, flattening, press-fitting, and fixing. The paper cup cover not only has good sealability and firmness, but also greatly saves paper, and is environmental-friendly due to the fact that no glue is needed.
