Definitions
- the present invention relates to an oxygen-absorbing composition and articles such as a container using the same.
- Gas barrier resins such as ethylene vinyl alcohol copolymer
- these gas barrier resins are materials excellent in oxygen gas barrier property and carbon dioxide gas nore property, and can be melt-molded. Therefore, these gas barrier resins are laminated with a layer of thermoplastic resin (polyolefin, polyester, etc.) excellent in moisture resistance and mechanical properties, and are suitably used as a multilayer plastic packaging material.
- thermoplastic resin polyolefin, polyester, etc.
- the gas permeability of these gas-nolia rosins is not zero, and a non-negligible amount of gas permeates the rosin.
- oxygen absorption Agents are being used.
- a composition containing a transition metal catalyst and an ethylenically unsaturated compound has been proposed (see JP-A-5-115776).
- a resin composition combining an ethylene vinyl alcohol copolymer and an oxygen absorbent has been proposed (Japanese Patent Laid-Open No. 2001-106866, Japanese Patent Laid-Open No. 2001-106920, Japanese Patent Laid-Open No. 2002-2002). No. 146217).
- the latter can be used for various packaging materials because it can be melt-molded in the same manner as the ethylene vinyl alcohol copolymer.
- oxygen absorbers using polymers having an ether structure have also been proposed (see Japanese Patent Application Laid-Open Nos. 2003-113311, 2003-245999, and US Pat. No. 6,746,622).
- an object of the present invention is to provide an oxygen-absorbing composition that does not generate an unpleasant odor when oxygen is absorbed.
- Another object of the present invention is to provide an oxygen-absorbing composition in which a compound that expresses oxygen-absorbing ability is dispersed in a resin with good dispersibility.
- the oxygen-absorbing composition of the present invention includes a compound having a molecular weight of less than 10,000 and an oxygen absorption accelerator, and the compound contains at least one ether bond. Contains two or more ring structures of
- ring structure means a structure of a skeleton constituting the ring, and does not include a substituent bonded to the ring.
- the oxygen-absorbing composition of the present invention may further contain gas norenic rosin.
- the laminate of the present invention includes a layer having the oxygen-absorbing composition power of the present invention.
- the container of the present invention includes a portion consisting of the oxygen-absorbing composition of the present invention.
- the oxygen-absorbing composition of the present invention has an excellent oxygen-absorbing property (oxygen scavenging property) and does not generate an unpleasant odor during oxygen absorption. Therefore, the composition of the present invention is useful as a container material for preserving articles such as foods and cosmetics that are susceptible to deterioration by oxygen gas and have a strong aroma. It is also useful as an oxygen scavenger because of its excellent oxygen absorption capacity and ease of handling.
