ABSTRACT:
The panel-like laminate comprises a flexible skin (1), a rigid substrate (2) and an intermediate layer (3). The flexible skin (1) comprises a main part (8) which forms the front side of the laminate and at least one flange (9) which extends from the main part (8) of the skin towards the substrate (2) to form at least a portion of the lateral side of the laminate. In order to avoid foam leakage when molding the intermediate layer (3) between the skin (1) and the substrate (2), the flange (9) is extended by a border part (10) which comprises a flexible lip (11). The flexible lip is pressed against the rigid substrate (2) so that the flexible lip (11) forms a seal between the skin and the substrate. To prevent deformation of the skin, the border part (10) of the skin further comprises at least one continuous or discontinuous ridge (12) which extends along the flange (9) of the skin (1) and which prevents a sliding of this border part when closing the mold.
