The company Honeywell sells the Aegis OXCE
polyamide, an oxygen absorber resin formulated to
ensure high barrier to PET bottles. From 5 to 7%
are added to the PET, keeping the PET transparency
and recyclability. The company Invista also holds the
active barrier technology, the OxyClear resin, which
contains high transparency oxidable polyester and
allows injection and blow molding and recycling of
PET bottles. ColorMatrix presents the Amosorb oxygen
absorber technology applied to mono and multilayers
bottles (Figure 6.2). Constar sells the Oxbar technology,
an oxygen absorber for multilayer PET bottles and
MonOxbar and Diamond Clear (high transparency)
for recyclable monolayer PET bottle. Valsper sells the
active barrier resin ValOR
TM
compatible with PET, long
term Activ 100 series and fast action Activ 300, for
mono and multilayer packages, to the food, beverage
and medical-pharmaceutical industry, which absorbing
function is activated by the moist of the product at the
package filling. Graham Packaging holds the Monosorb
oxygen absorber technology for monolayer PET bottle.
In the field of bottle caps, Grace Darex Packaging
Technologies has an oxygen absorber technology called
Celox.

The package with the incorporation of
antioxidants is another type of active package that
can be used for the control of lipid oxidation. It acts
mainly by the mechanism of radicals scavenging,
avoiding the propagation of the oxidation reactions.
Synthetic antioxidants approved for food contact are
options as antioxidants agents, as well as antioxidants
natural extracts, which have been the target of recent
studies. One of the suggestions is the association of this
technology with the moisture and/or oxygen absorbers,
increasing the food protection potential.
The direct addition of antioxidants in food and
beverages is very common, since they are approved for
use as food additive. However, in fresh food and in many
Packages with antioxidants
