Abstract
Improved oxygen barrier and oxygen absorbing compositions and structures comprising blends of xylylene group-containing polyamides and cobalt octoate and xylylene group-containing polyamides, polyesters and cobalt octoate are disclosed and claimed. These blends have superior barrier properties and clarity obtained by controlling the degree of orientation and the amount of cobalt. These novel blends are used as single layers and as the core layer in multiple layer films, structures and articles. When used in multiple layer structures, the adjacent layers are comprised of polyesters and/or polyamides. The structures made from the blends of the present invention have a clarity that is superior to structures previously known in the art.
