PACKAGING MATERIAL FOR PERISHABLE FOOD

摘要

PROBLEM TO BE SOLVED: To obtain the subject packaging material having freshness-keeping property and antibacterial property by using a mixture component containing a water-soluble mineral component derived from feldspar, quartz stone and clay ceramic, an antibacterial zeolite and a water-soluble paste and fixing the mixture component to a sheet substrate. SOLUTION: The objective packaging material having freshness-keeping property and antibacterial property and suitable for the packaging of perishable food can be produced by fixing a mixture component composed of several to several hundred ppm of a water-soluble mineral component derived from feldspar, quartz stone and clay ceramic, 0.1-5.0 wt.% (based on the treating liquid) of an antibacterial zeolite such as silver zeolite and 0.05-0.5 wt.% of a natural or synthetic watersoluble paste such as a water-soluble resin (e.g. polyvinyl alcohol or its modified material), (modified) starch and (modified) cellulose to a sheet substrate such as a waterabsorbing nonwoven fabric, paper, foamed material, plastic film and/or a laminate with aluminum foil.
