1. A floor panel having a rectangular and oblong shape with a pair of longitudinal opposite edges and a pair of short opposite edges, said floor panel comprising a substrate and a top layer provided on said substrate;
wherein said top layer comprises from bottom to top a thermoplastic back layer located on the substrate, a print provided on a synthetic material film and a transparent thermoplastic layer based on polyvinylchloride situated above said print; the synthetic material film being located between the back layer and the transparent thermoplastic layer, and the print being provided between the transparent thermoplastic layer and the synthetic material film; said top layer forming a decorative side of said floor panel; wherein said substrate is based on a thermoplastic material chosen from the list consisting of polyvinylchloride, polyethylene, polypropylene and polyurethane; said substrate having an overall thickness of 2 to 10 millimeters; said thickness being larger than half of the thickness of the entire panel; wherein said floor panel at least at said pair of longitudinal opposite edges is provided with coupling parts allowing to couple two such floor panels to each other, such that, in a coupled condition, said two floor panels are locked to each other at the respective edge in a vertical direction perpendicular to the plane of the coupled panels, as well as in a horizontal direction perpendicular to the coupled edges and in the plane of the panels; wherein said coupling parts are formed as a tongue and a groove, wherein the contour of said tongue and groove is substantially realized in said substrate with said back layer extending above a horizontal level determined by a center line of said tongue and groove; wherein said floor panel has a length of more than 118 centimeters, and a width between 8 and 22 centimeters. |
