Optical Disc Packaging - Keep Case

A keep case is the most common type of DVD packaging. It is taller and thicker than a Jewel case, and is made of much softer, less brittle plastic (polypropylene rather than polystyrene), so it does not break as easily. They usually hold one or two discs, but are capable of holding up to six discs. Slimmer keep cases, so called "Slim-paks" or "Thinpaks" typically used for DVD box sets consisting of the thin keep cases stored in a paperboard box. The thin cases are half as thick and can generally only hold one disc as a result, but there are newer slim cases that have central disc holding teeth on both sides. The teeth are made in such a way that when the case is closed, they go between the gaps in between the teeth on the other side.

A standard DVD case is a single-piece plastic case with two creases, which folds around and snaps closed. It measures 135 mm x 190 mm x 14 mm (5.3 in x 7.48 in x 0.55 in). It is wrapped on the outside by a thin piece of transparent plastic which can hold a paper label. The label measures 284 mm x 184 mm (10.8 in x 7.25 in).

Some DVD releases have a cardboard outer sleeve around the shrinkwrap.

Current (early 2007) prerecorded Blu-ray Disc and HD DVD titles ship in packages similar to but slightly smaller (18.5 mm shorter and 1 mm thinner: 135 mm x 171.5 mm x 13 mm. ) than a standard DVD keep case, generally with the format prominently displayed in a horizontal stripe across the top of the case (red for HD DVD and PlayStation 3 Greatest Hits Games, blue for Blu-ray, and clear for PlayStation 3 regular games).
