A multi-layer card comprising a polymeric inlay layer having a first surface and a second surface, further comprising a first multi-layer film which is disposed on the first surface of the polymeric inlay layer, and further comprising a first polymeric overlay layer which is disposed on said first multi-layer film, such that the layer order is polymeric inlay layer, first multi-layer film and first polymeric overlay layer, wherein said first multi-layer film comprises: (i) a polyester base layer (B) comprising a crystallisable polyester (P B ), and further comprising titanium dioxide in an amount of from about 1 to about 30 wt% by total weight of the base layer; (ii) a first heat-sealable copolyester layer (A1) disposed on a first surface of said polyester base layer; and (iii) optionally a second heat-sealable copolyester layer (A2) disposed on a second surface of said polyester base layer, wherein the copolyester (CP A ) of each of the first and optional second heat-sealable copolyester layers is independently selected from amorphous copolyesters (ACP A ) derived from an aliphatic diol and a cycloaliphatic diol and at least one aromatic dicarboxylic acid, and/or the polyester base layer (B) further comprises a copolyester (CP B ) in an amount of at least about 10% by weight based on the total weight of the base layer (B). |
