Abstract: The invention concerns a thermoplastic multilayer sheet (1) which is opaque in transmission, having a density of 1 g/cm3 or less and a thickness of 500 ?m or less, each of its faces having a uniform surface finish, said sheet comprising at least three extruded layers including an opaque internal layer (2) and at least two external layers (3, 4) of thermoplastic ma which is not completely opaque, said internal layer (2) comprising a thermoplastic material and an opacifying charge. The invention also concerns a method for manufacturing said opaque thermoplastic sheet (1) comprising a step for co-extrusion and a step for “press-cool-finishing” said co-extruded polymer (5) between a cooling roll (7) and an endless belt (8) providing said sheet (1) with the required thickness and a uniform surface finish. It also concerns its application to various sheets, in particular hanging banners or playing cards or scratch cards.
