Abstract
An economical, three-dimensional reusable plastic article that is resistant to damage and stress caused by a variety of factors is disclosed. The plastic article comprises a polycarbonate/polyester plastic blend, and optionally further comprises a plastic insert. The polycarbonate/polyester blend may be fused directly to the optional plastic insert. Alternatively, the polycarbonate/polyester blend may be tied to the optional plastic insert through the use of an adhesive layer and/or a tie layer.
