Abstract
A package structure for a recording medium or other items is composed of a plastic support frame and a laminated flexible body. The package structure consists of a molded plastic frame having two sections forming the lid and the base of the package, separated by a hinge which allows the lid and base sections to fold together to close the package. In a preferred embodiment, the package body is formed of a folded paperboard blank. The plastic frame is slotted at opposite ends to allow the paperboard blank to extend through the frame from outside to inside. The blank is folded at the slots, and is folded onto itself to form the surfaces of the package. The frame is formed with recesses adapted to receive the body surfaces to protect the surfaces and the edges of the outer body surfaces. The portions of the body which respectively form the inner and outer surfaces of the lid, and the inner and outer surfaces of the base are secured together and/or to the corresponding frame section. A portion of the body overlies, but is not secured to the frame hinge so that the two move separately when the package opens and closes.
