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.
An improved clear oxygen barrier and oxygen absorbing multiple layer structure comprising a core layer comprising a blend of a xylylene group-containing polyamide and up to 250 ppm of a transition metal catalyst disposed between two polyester layers.
An improved clear oxygen carrier and oxygen absorbing multiple layer structure comprising a core layer comprising a blend of MXD6 nylon and up to about 250 ppm cobalt octoate disposed between two layers of PET.
An improved clear oxygen barrier and oxygen absorbing composition comprising a blend of polyester, a xylylene group-containing polyamide and up to 250 ppm of a transition metal catalyst, wherein, the composition is oriented to a degree so that the MXD6 domain increases in size up to less than the wavelength of light.
An improved clear oxygen barrier and oxygen absorbing composition comprising a blend of a polyester with oxygen barrier properties greater than polyolefins, a xylylene group-containing polyamide and up to 250 ppm of a transition metal catalyst.
An improved clear oxygen barrier and oxygen absorbing multiple layer structure comprising a blend of a first polyester, a xylylene group-containing polyamide and up to 250 ppm of a transition metal catalyst disposed between two layers of a second polyester, wherein, the structure is oriented to a degree so that the MXD6 domain increases in size up to less than the wavelength of light.
