A new series of oxygen scavenging additives can be dispersed directly into packaging materials, offering a more convenient alternative to conventional scavenging techniques such as UV-activated systems and oxygen scavenger packets. O2Block additive is primarily designed to maximize 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. 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.
