Title:
METHOD FOR PRODUCING OXYGEN−CAPTURING PACKAGING MATERIAL AND OXYGEN−CAPTURING PACKAGING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2003/025048
Kind Code:
A1
Abstract:
A method for producing an oxygen−capturing packaging material, which comprises blending an ethylene−vinyl alcohol copolymer or polyethylene terephthalate as a carrier of a barrier resin with an oxygen−capturing agent to form an oxygen−capturing resin for dispersion, dispersing the oxygen−capturing resin in a polyolefin or polyamide as a matrix resin to form an oxygen−capturing composite material, and forming a packaging material by the use of the oxygen−capturing composite material. A container formed by using the packaging material exhibits excellent oxygen−barrier properties and excellent mechanical strength with a thinner thickness, and thus may be reduced in weight.
