摘要：
A laminate includes the following substantially coextensive layers in the following order:
(a) a non-sealable, self-supporting, thermoformable copolyester film layer having a first surface and a second surface, the second surface constituting an outermost, exposed surface of the laminate;
(b) a laminating adhesive layer on the first surface of the thermoformable copolyester film layer; and
(c) a self-supporting, thermoformable structural film layer having a first surface and a second surface, the first surface contacting the laminating adhesive layer.
