摘要： The present invention provides a sturdy display package which, in an embodiment, is made of first and second peripherally sealed transparent PVC sheets approximately 7.5 mils thick each. The package is particularly useful for displaying and protecting small items such as pain reliever packets or condoms. The invention includes a method and apparatus for making such a package. The first sheet is positioned over a nesting plate having a plurality of nesting modules, each corresponding to one package and being independently height-adjustable by a shim at a selected location to correct sealing flaws. The second sheet is then positioned over the first sheet so that the items are between the sheets. An RF-sealing die is provided having package-shaped sealing dies, each defining a pocket. The sealing die and nesting plate are pressed together so that each pocket receives a bulge formed by from one of the items. Each pocket has a foam insert which resiliently deforms and presses the second plastic sheet peripherally around the item. The RF sealing die nests against the nesting plate forming a plurality of seal areas, each enclosing one of the items and defining one package. The individual packages may then be cut from a resulting composite sheet.
