A new series of oxygen scavanging additive can be dispersed directly into packaging materials, offering a more convenient alternative to conventional techniques such as UV-activated systems and oxygen scavenger packets.  The technology uses purified and modified layered clay as a performance- enhancing carrier of the oxygen-scavenging iron.
Oxygen is depleted from the package by migrating through the packaging material and reacting with the dispersed active iron from the additive. The reaction is swift and produces iron oxide, which is linked inside the packaging.
The manufacturer, NanoBioMatters, states that the "O2Block®" additive is primarily designed to maximise shelf life for diverse packaging made of materials such as low and high density polyethylene (LDPE, HDPE), polypropylene (PP), Polyethylene Terephthalate (PET) and polylactic acid (PLA) for the food and pharmaceutical industries.

Potential Benefits

The greatest benefit of this type of technology is in it's potential to maintain product quality and extend shelf life thorugh the use of oxygen scavenging additive in the packaging.
Unlike other oxygen scavenging solutions this product utilises less packaging as the oxygen scavenger additive is dispersed within the packaging rather than being held in a sachet within the pack.

Intellectual Property

NanoBioMatters has a patent pending on the O2Block®" technology.

Consultant View

Oxygen scavengers have been trialled in the past as a way of enhancing product shelf life. But unlike other oxygen scavengers, this technology has the aded advantage of being dispersed within the packaging.  There are many other examples of Oxygen barrier technologies held on the REID database and researchers are advised to search the database using terms such as "Oxygen barrier technology" and "shelf life extension".
