OXYGEN-SCAVENGING RESIN COMPOSITIONS AND CONTAINERS HAVING LOW HAZE AND RELATED METHODS

摘要

A resin composition provides good optical properties when stretched and efficient oxygen-scavenging, the resin composition comprising a film-forming polyester and an effective amount of oxygen-scavenging particles, wherein the particles have a particle size distribution such that particles of less than about 25 microns in size do not exceed a concentration defined by a formula that includes the apparent density of the particles. A container provides effective oxygen-scavenging functionality, while having low haze. A method is also provided for incorporating high levels of oxygen-scavenging particles into a film-forming polyester resin composition with low haze when stretched.
