Disadvantages are poor protection of the delicate label surface, and direct contact between the readout surface of the disc and the bottom of the tray. Any contamination in the bottom of the tray can damage the disc as the package is bounced around. The jewel case remains the package of choice, suspending both surfaces and the rim within the box, and preventing their contact with surfaces contaminated by debris or grit that can damage the disc during vibration or shaking. Some manufacturers have added high impact polystyrene to the crystal polystyrene used for conventional cases. The result is a more rugged case that is less likely to fracture.
Some boxes are available that use polypropylene, a proven video tape packaging material.
All require secondary protective packaging for mailing. Innovative suppliers will continue to offer new and useful options. Evaluate them by their ruggedness and by their ability to suspend the disc. Clean, plastic wallets lined with non-woven fiber can be an excellent alternative provided that they are surrounded by additional protection.
