Any number of polylines or polygons can reside in the same file. Each one begins with a single line header that is used as the "ID" of the polyline or polygon. Next comes the data in either 2D or 3D format, the importing automatically handles either. Finally, the polyline or polygon is finished (not necessarily "closed") by an "*" in column 1. There is no difference between polyline and polygon in a P2D file, only how the data are treated by the application reading the file.
