Ever greater use is being made of oxygen measurement via extinction of luminescence in order to characterize oxygen scavengers and to determine the oxygen transmission of packaging materials such as PET bottles and films. Fraunhofer IVV has been involved with the development of active packaging materials for many years. On the proposal of the institute and with the involvement of the Active Packaging / Oxygen Scavenger Subcommittee (NA 115-02-06 AA) of the Packaging Standards Committee (NAVp) of DIN, two draft standards have been prepared:
- E DIN 6139-2 ”Packaging - Oxygen scavengers for packaging applications -
Part 2: Determination of the rate of reaction“ and
- E DIN 53380-5 ”Testing of plastics - Determination of gas transmission rate -
Part 5: Optical method for plastic films and moulded plastic parts”
The drafts are available in German and can be purchased in printed or electronic form from Beuth Verlag GmbH (www.mybeuth.de). In the period from 8 November 2013 to 8 March 2014 the standards can be accessed free and commented on via the draft standard portal of DIN (www.entwuerfe.din.de).
