CD Casing

April 12th, 2007

The simplest, least expensive package is a paper envelope. More expensive versions add a transparent window to the envelope allowing the disc label to be seen. The envelope can also be made out of spin-bonded polyethylene (trade-named Tyvek); this is both more durable and less abrasive than paper. However, such packaging is rare for commercial releases due to its relative lack of protection compared with other designs, and is primarily limited to promotional and demo discs. These are normally called as CD Paper Sleeves and are the most easiest way to store.

One more is a jewel case is the original compact disc case that has been used since the compact disc was first released in 1982. It is a three-piece plastic case, measuring 142 mm × 125 mm × 10 mm, which usually contains a compact disc along with the liner notes and a back card. Two opposing transparent halves are hinged together to form the casing, the back half holding a media tray that grips the disc by its hole. All three parts are made of injection-molded polystyrene.

The original jewel case structure has a weakness in that the case is hinged on two brittle plastic arms, which often break if the case receives shock or stress. The teeth of the hub holding the disc are also prone to failure. An opposite problem are the tabs which hold the liner notes in place; sometimes, especially with larger booklets, the tabs grip the booklet too tightly, leading to tearing.
