Abstract

In the packaging of limited lifetime DVDs, one problem that must be dealt with is that the shelf life of the DVD product is not in all cases sufficient for extended distribution times. One solution is to adhere the OS film to a limited lifetime DVD by use of a temporary, non-contaminating, adhesive or low temperature sealant so that the product integrity can be maintained over a longer period of time. In laboratory shelf life evaluation, it has been noted that when an oxygen scavenging film "sticks" to the DVD product, the color is retained for several weeks. In some cases, the color is retained for months after the remaining portions of the DVD product have become discolored. This indicates that a temporary bond, whether by the addition of a temporary "tack" adhesive (for example Poly-Mask™) to the sealant layer of the oxygen scavenging film, or the use of a low temperature sealant, can significantly enhance the shelf life of the DVD product. The sealant in this case is the surface of the film in contact with the DVD.
