Consumer aspects Some types of scavengers (monolayer barrier material) are not accepted well due to the pearlescence and haze, which drastically reduces its attraction on the shelf.
Database search history Web of science: Barrier packaging materials oils - 53 articles were found, no all are relevant, also sources from internet (Google) were used.
Environmental aspects Improved recyclability (Compatible with PETE-1 recycling streams), PET containers with monolayer barrier material also deliver freight savings and reduced greenhouse emission.

Match with potential needs/short comings Prolonged shelf life and improved quality of oil and fat products compared to ordinary PET packaging, comparable barrier properties with glass packaging (depend on type of scavenger).
Maturity This technology of packaging is used in in This technology of packaging is used in industry. Many kinds of active polymeric scavenger are available under different trademarks (Oxbar® , MonOxbar® , DiamondClear®, Amosorb® etc.). Differences are mainly in structure of layer (multi-layer, monolayer) and materials. er (multi-layer, monolayer) and materials.

Title Active barrier packaging materials for fat and oils  +
Working principle This technology is based on the enclosure This technology is based on the enclosure of an oxygen scavenger in the packaging material. An oxygen scavenger is a material or combination of reactive compounds and reacts with oxygen to provide enhanced barrier protection for oxygen sensitive products. It is incorporated into layers of containers where it controls oxygen and CO2 permeation and protects product integrity. For liquid foods, a polymeric oxygen scavenging system is suitable. This active barrier reduces, e.g. for extra virgin olive oil, the decline in antioxidant activity during storage in PET bottles. Oxidation of products is lower than in simple PET bottles stored under the same conditions [1, 4]. Materials having high oxygen barrier properties, for example PET with oxygen scavenger slow down the quality decay kinetics to larger extent, as compared to PET alone [2]. The performance of active barrier PET containers may move towards that of glass bottles (which have high oxygen barrier properties). E.g. mayonnaise stored in PET containers with an oxygen scavenger incorporated during extrusion has comparable oxidative stability as stored in glass [5]. Passive barriers (simply blocking the passage of oxygen through the packaging walls) partially lose their capability as the temperature rises. Active barriers, however, are oxygen-scavenging materials that re-balance their rate of reaction to follow changes in temperature. reaction to follow changes in temperature.
