Patent ID: 7785680

Claim:
A multilayer card comprising a first multilayer film structure, said multilayer film structure comprising: (i) an opaque polyester film substrate comprising in the range from 0.2 to 30% by weight relative to the total weight of the substrate, of at least one copolyesterether comprising at least one alkylene terephthalate; (ii) a first ink-receptive layer on a first surface of the substrate; (iii) a cover layer on the surface of the first ink-receptive layer; and (iv) a second ink-receptive heat-sealable layer comprising a polyester resin on a second surface of the substrate; wherein said second ink-receptive heat-sealable layer constitutes an outermost layer of the first multilayer film structure, and wherein the second ink-receptive heat-sealable layer is capable of forming a heat-seal bond to itself having a strength in a range from 300 to 3000 N/m when bonded for ten seconds at 140° C. and 275 kPa.
