Monolayer packages comprised of an oxygen scavenging composition suitable
for direct contact with package contents and recycle with other polyester
bottles are disclosed. The oxygen scavenging composition is comprised of
a modified copolymer which is comprised of predominantly polyester
segments and an oxygen scavenging amount of oxygen scavenging segments.
The polyester segments comprise segments derived from typical bottling
and packaging polyesters such as PET and PEN. Use of these oxygen
scavenging copolymers in bottles provides a clear and rigid monolayer
bottle similar in appearance to unmodified polyester bottles. In a series
of preferred embodiments, bottles fabricated with the oxygen scavenging
copolymers of this invention are over 99 wt % PET and contain less than
50 ppb of extractable components.
