DVD Cases

A DVD case-also referred to as a poly-box, keep case or Amaray case-is an optical media package specifically targeted for the distributionof DVD discs. A majority of the world's pre-recorded DVDs are commercially distributed in DVD cases. They are used for movies, audio books and video games for systems like Playstation 2 and 3, Nintendo Wii, Microsoft Xbox and Xbox360.

A DVD case is engineered from flexible polypropylene plastic-a thermoplastic polymer found in common heat-resistant products like Tupperware, car parts, stationery and carpet. The case's outer entrapment cover is made with a thin layer of clear package-grade polyethylene. The inner tray of the folded case is molded to fit the dimensions of a DVD. The colors inside the cases may vary. For example, Xbox uses a signature neon green. The inside of the case contains tab clips that prevent paper insert information from falling out or shifting.

The disc itself is anchored to the case not only by the slight molding but by the center hub. The center hub may come in a wide variety of configurations that strive for sturdy disc locking and easy removal. A DVD's hub is purposely engineered with weaker materials than a CD's hub because the composition of a DVD is more delicate. Therefore, storing a DVD in a CD case with a stronger hub should be avoided to protect the disc from damage.

DVD Case Dimensions

Case hubs come in push button formats or pluck formats in which the user is required to carefully lift the locked disc out of place without bending or breaking it. It is common for manufacturers to patent their own unique version of a DVD case hub, as several types exist on the market.

While similar in storage concept, a DVD case is larger and more flexible than a standard CD jewel case. A DVD case's closed dimensions are 190mm by 135mm with a standard width for single cases at approximately 14mm. Widths may vary depending on if it's a slimmer version or if it holds multiple discs per case.

Consumers can purchase blank and empty DVD cases to customize a media project or replace a broken package. These cases can be personalized through outer covers or inner booklets created by the consumer or a printing and duplication service.
