Title:
IRON-CONTAINING OXYGEN ABSORBING RESIN COMPOSITION, AND PACKAGING MATERIAL AND CONTAINER USING THE SAME
Document Type and Number:
Japanese Patent JP3669414
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress the generation of hydrogen during storage by adding a disoxidant containing iron power and a pro-oxidant to a thermoplastic resin, specifying the amount of the pro-oxidant in the iron powder and further incorporating a specified amount of a polyhydric phenol compound in the iron powder.
SOLUTION: A disoxidant containing iron power and 1-30 wt.% pro-oxidant based on the amount of the iron powder is added to a thermoplastic resin and 0.1-5 wt.% polyhydric phenol compound based on the amount of the iron powder is further incorporated to obtain the objective iron-containing oxygen absorbing resin composition used for a packaging material which hermetically packages contents. When contents are hermetically packaged with the packaging material, oxygen in the inside is rapidly absorbed and the generation of hydrogen during storage is suppressed. The polyhydric phenol compound is preferably selected from catechol, pyrogallol, gallic acid and their derivatives and the amount of the compound is preferably smaller than the amount of the pro-oxidant.
