Perishable DVDs need oxygen-scavenging film

A DVD that lasts 48 hrs after opening relies on an oxygen-scavenging film to preserve its packaged ‘freshness’.

A DVD with a freshness date? That’s the basis for ez-D™, a perishable, no-return, no-late-fee DVD from Disney’s Buena Vista Home Entertainment Div., Burbank, CA, that plays into consumer convenience.

Crucial to the concept is the packaging, which relies on the Cryovac OS System of oxygen-scavenging technology from Cryovac Div. of Sealed Air. The system comprises film and specialized in-plant equipment. This is the first nonfood application for OS technology.

Once the ez-D package is opened, a proprietary oxidation process begins that discolors the disk and makes it unreadable after 48 hours. Until then, it remains viewable as many times as the user desires. Unopened, the ez-D packs have a one-year shelf life preprinted on the sleeve as “Product Freshness Guaranteed Until” followed by the date.

The perishable DVD technology was developed by Flexplay Technologies, which licenses its technology to Technicolor Home Entertainment, a division of Thomson that packages the ez-Ds. Referred to as a “partner” by Flexplay, Technicolor is basically a contract packager.

In-plant details

Technicolor has been operating a Multivac Model R 240 thermoform/fill/seal machine since April 2004 to produce the packs in a 2x4 pattern at a rate of 10 cycles or 80 packs/min.

Cryovac’s 4104 Series ultraviolet light-triggering system—four banks of UV lights—that activates the film’s oxygen-scavenging ability straddles the tf/f/s system. The system also includes a Scavenging Verification System, an online quality control system that confirms that the film has been activated.
