Patent ID: 7740926

Claim:
A container having at least one wall, wherein the wall is a monolayer and comprises a populated area, and wherein the populated area comprises: a film-forming polymer selected from the group consisting of polyethylene terephthalate, copolymers of polyethylene terephthalate, polyethylene naphthalate, copolymers of polyethylene naphthalate, polybutylene terephthalate, copolymers of polybutylene terephthalate, polytrimethylene terephthalate, and copolymers of polytrimethylene terephthalate; and a population of particles comprising an effective amount of oxygen-scavenging particles, wherein the number of oxygen scavenging particles does not exceed a concentration of (1×10 7 particles÷T) per cubic centimeter of polymer wherein T is the thickness of the populated area in mils; wherein the oxygen scavenging particles comprise an element selected from the group consisting of calcium, magnesium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, silver, tin, aluminum, germanium, silicon, lead, cadmium, and rhodium; wherein the change in the transmission Hunter L* of said wall is less than 0.4 per mil of the container wall when compared to a control that does not contain oxygen-scavenging particles, and the concentration of oxygen scavenging particles is less than 3000 parts per million parts of populated area.
