<p>PROBLEM TO BE SOLVED: To obtain a deoxidizing resin composition excellent in processing stability, scarcely emitting a malodor and slightly deteriorating a polyolefin which is a constituent material with time. SOLUTION: This deoxidizing resin composition comprises 10-80 wt.% of a deoxidizer, 20-90 wt.% of a polyolefin and 10-20,000 ppm of at least one antioxidant selected from the group consisting of a phenolic antioxidant, a phosphorus- based antioxidant and a lactonic antioxidant. The antioxidant is a mixture of at least one antioxidant selected from the group consisting of the phosphorus- based antioxidant and the lactonic antioxidant with the phenolic antioxidant. The content of the antioxidant is 100-20,000 ppm and the deoxidizer is a deoxidizer containing a reducing substance causing an oxygen absorbing reaction by receiving the feed of moisture as a principal ingredient. Thereby, the deterioration of the polyolefin resin is suppressed at the time of thermal processing and preserving and the emission of a malodor and the deterioration of strength are prevented.</p> |
