Clear CD Jewel Cases
There are many different types of jewel cases available for the storage of CDs. I am concerned that some may be harmful to CD over a long period of time and therefore want to store my discs in the proper jewel case. In particular, are the clear CD jewel cases better than those which are not clear?
When you mention the word clear, it may refer to two things with regards to a jewel case, the case itself or the holding tray. First of all the holding tray of the jewel case can come in various looks including clear, white, black, gray, and various other colors. Whether the clear CD jewel cases are safer in the long term or not than the other alternatives for your CDs is a question that presently cannot be answered. There has been some speculation that some cases are worse than others, but this is just speculation or anecdotal. There has been no scientific testing to establish what effect different types of trays have on CDs or other optical disc media. However, because the clear cases are likely to contain less additives, such as dyes, fillers, etc., then they might be a better choice overall.
The other issue of clarity is with respect to the actual case. The clear CD jewel cases are made of polystyrene. The main problem with these cases is that they are fragile and often crack or shatter. Another type of jewel case that is available is made of polypropylene. These cases are not as clear as the polystyrene ones, but still translucent enough to see the disc or insert materials inside. These polypropylene jewel cases are ideal for situations where the case is being handled frequently because they will not crack or shatter and are a lot more durable.
