Dual use plastic packages for prepackaged retail product are constructed to be recyclable, making the package environment friendly. The package also provides an in-the-package display of the packaged product, and allows for inclusion of advertising and promotional material. The basic package structure is formed of injection molded virgin clarified polypropylene material, a transparent material. In one embodiment a sheet of advertising material is held in a thin narrow sleeve formed on the outside surface of the package, allowing the paper sheet to be withdrawn during recycling operations. In another embodiment, the printed material is printed on the thin plastic sheet, which is clearly recyclable, although recovering a darkened plastic when recycled. A novel lock device is disclosed. Either or both those packages or any other retail packages may include the lock device to prevent the package from being opened in store. In this, the lock device includes a lock bar.
