Provided is a resin composition which is excellent in an oxygen-absorbing performance, a resin strength and a resin processability.The oxygen-absorbing resin composition is characterized by containing a polyolefin resin, a transition metal catalyst and a polyamide resin obtained by polycondensation of aromatic diamine and dicarboxylic acid, wherein an end amino group concentration of the above polyamide resin is 30 μeq/g or less, and a total content of the transition metal catalyst and the polyamide resin is 15 to 60% by weight based on a whole amount of the oxygen-absorbing resin composition.
Abstract:
The invention is a method, triggering unit, and system for activating an oxygen scavenging composition at high speeds. The triggering unit includes a plurality of UV lamps that can operate at increased temperatures and have high output intensites from about 10 to 35 mW/cm2. The triggering unit can activate films at speeds from about 20 to 100 fps. Mercury amalgam lamps are useful in the practice of the invention. The invention also includes a UV dose management system and film tensioning system that facilitates triggering at high film speeds. The UV dose management system controls the amount of UV exposure that the film receives so that the oxygen scavenging rate of the activated composition can be controlled.

Abstract:
This invention discloses a process and a necessary article to simultaneously thermally treat at least two thermoplastics. The process utilizes the necessary compartmentalized or zoned pellet construction wherein the major amount of each thermoplastic component is located within individual compartments or zones of the pellet such that the components of the reaction during thermal processing and/or reactions with compounds in the atmosphere such as oxygen are less than the reaction if the thermoplastics were homogeneously dispersed in the pellet. This invention allows the components of the multi-component pellets to be thermally treated together without significant degradation and/or stored in air or in the presence of oxygen without significant degradation.
