A process for manufacturing a non-opaque layer (12) for a multilayer structure (28) comprising at least one window (30), the process comprising the steps of a) providing at least one layer (12) of a non-opaque plastic material , having an initial thickness, characterized in that it further comprises b) providing a stamped plate (14) having at least one cavity (16) whose size corresponds to said at least one window (30), c) covering at least one area of said at least one layer (12) of non-opaque plastic material with the stamped plate (14), the cavity (16) being open towards a first surface of said at least one layer (12) of non-opaque plastic material, d ) pressing the stamped plate (14) against the first surface of said at least one layer (12) of non-opaque plastic material, to form in said at least one layer (12) of non-opaque plastic material, at least one first region ( 13) and a second region (15), the second region (15) corresponding to the cavity ( 16) and having an extra thickness compared to the first region (13), e) removing the stamped plate (14) from the first surface of said at least one layer (12) of non-opaque plastic material. |
