OXYGEN-ABSORBING MIXTURES Russian patent published in 2013 - IPC C08K3/08 A23L3/3436 B01D53/04 B65D65/38 C08L101/00 C08K3/16 C08K3/22 

FIELD: chemistry.

SUBSTANCE: invention relates to production of packaging materials (packaging walls and packaging articles) for food products and specifically relates to an oxygen-absorbing mixture used as an oxygen absorbent in food packaging, a composition containing a polymer resin and said oxygen-absorbing mixture and an article - packaging. The oxygen-absorbing mixture contains (I) an oxidisable metal component, (II) an electrolytic component selected from a group consisting of KCl and CaCl₂, and (III) a non-electrolytic oxidising component. The mixture also contains a water-absorbing binding agent, e.g. zeolite, graphite, soot or clay. The composition used to make packaging articles contains a polymer resin, e.g. an olefin homo- or copolymer, polyamide (co)polymers, said oxygen-absorbing mixture and an optional additive selected from a group comprising UV absorbents, antioxidants and other light stabilisers. The packaging article is a film, a sheet or layered material.

EFFECT: invention increases oxygen absorption activity of packaging materials, eg films, the oxygen absorbent has excellent longevity.
