Title:
PACKAGING MATERIAL FOR DEOXIDATION AGENT
Document Type and Number:
Japanese Patent JPH0258570
Kind Code:
A
Abstract:
PURPOSE:To provide a packaging material for deoxidation agent, made of a film composed of graft copolymer resin of an olefinic polymer and a polyorganosiloxane and usable in contact with a liquid or a liquid-containing substance for a long period without causing the lowering of gas-permeability and the permeation of the liquid. CONSTITUTION:A film is produced from a graft copolymer resin produced by the graft polymerization of 100 pts.wt. of an olefinic polymer (e.g., polyethylene or polypropylene) and 50-300 pts.wt. of a polyorganosiloxane. As an alternative method, the film is produced from a resin mixture produced by mixing 100 pts.wt. of the above graft copolymer and 10-1,000 pts.wt. of an olefinic polymer. If necessary, the film is laminated with a gas-permeable sheet composed of paper, nonwoven cloth, etc.
