Try this:

using (ExcelPackage p = new ExcelPackage())
    //Code to fill Excel file with data.

    Byte[] bin = p.GetAsByteArray();

    Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
    Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", Nombre_Del_Libro + ".xlsx"));
