2. Description of the Related Art As a packaging material having an antibacterial property, a technique of mixing an antibacterial zeolite into a container and a packaging material for fresh food,
Alternatively, a technique is known in which an antibacterial layer containing an antibacterial zeolite is provided on the inner surface of the container. For example, as the technology of mixing the antibacterial zeolite into the former resin packaging material,
As disclosed in Japanese Patent Application Laid-Open No. 1-8019, a food container is formed by mixing an antibacterial zeolite with a thermoplastic resin such as polystyrene, polyethylene, or polypropylene to form a sterile container. As the latter technology for providing an antibacterial layer on the inner surface of a packaging material, there is Japanese Utility Model Laid-Open No. 2-141373, but here the packaging material is used as a packaging material for transporting goods such as fruits and vegetables or fresh foods or for display at stores. An antibacterial layer containing an antibacterial zeolite is provided on the inner surface side of the sheet to impart antibacterial properties. Further, in Japanese Utility Model Laid-Open Publication No. 1-89128, drip absorption from food etc.,
In the sheet for promoting fresh flower packaging, or for promoting the growth of plants and roofing, the antibacterial zeolite held on the sheet exerts antibacterial properties by activating oxygen in the air, and the occurrence and growth of mold and various bacteria There are known techniques that prevent this. The above prior art uses a typical silver zeolite as an antibacterial zeolite in a food container or packaging material as described above, and exerts antibacterial properties by suppressing the growth of microorganisms by silver ions contained therein. Although not intended, there has not yet been developed a technique for maintaining the freshness over a long period of time by preventing the freshness of the packaged food from wilting and discoloring at the same time as having antibacterial properties.

As a technique for maintaining freshness of fresh food, a technique of freezing and refrigeration has been known for a long time, but a relatively new technique of maintaining freshness by controlling components in a storage atmosphere is also known. However, although both are technologies that have been put into practical use in relatively large units, although the need for simple packaging materials that are routinely used in the route from distribution and transportation of fresh food to store display is eagerly desired, In reality, there was no disclosure of useful practical packaging materials. In order to impart the above antibacterial properties, suppressing the growth of mold and various bacteria by an antibacterial zeolite utilized as an antibacterial agent is an extremely hygienic agent as a countermeasure against food poisoning. No effective freshness preservation measures could be taken. That is, with the use of the above antibacterial agent, fresh vegetables and fruits are withered over time, for example, visually preventing browning of cuts such as lettuce, darkening of meat or freshly preventing deterioration of eggs. I couldn't do that. As described above, conventionally, there has been a demand for a product that is convenient for maintaining freshness in a storefront display from distribution and transportation, but there has been no practically effective means. The present invention is a packaging material for keeping freshness which is simple as a packaging material for fresh food used for store display from distribution and transportation, and not only keeps freshness by preventing wilting, discoloration or deterioration of fresh food, but also at the same time An object of the present invention is to provide a packaging material that also exhibits antibacterial properties.

It is effective to use Kanebo Corporation product). Also,
It is possible to use zirconium silver phosphate or calcium silver phosphate in addition to silver zeolite as the antibacterial zeolite. However, the antibacterial property is inferior to silver zeolite, so it is necessary to add a larger amount than silver zeolite. The antibacterial zeolite is used in the range of 0.1 to 5.0% by weight. In the case of silver zeolite, the antibacterial property is sufficiently exhibited at 0.1 to 3.0% by weight, but when using other antibacterial zeolites, the upper limit is used. It is necessary to use up to.

In order to maintain freshness, the presence of a mineral component, an antibacterial zeolite and a synthetic or natural paste component in the composition water is indispensable. As fresh food such as vegetables progresses drying, Since the composition water used for the treatment is inevitably reduced, the vegetables begin to wither. At this time, simply imparting general water to the surface is rather a daily experience that rot is rather accelerated. On the other hand, the reason for maintaining the freshness by the mineral component in the present invention is not certain. However, it is thought that hydrates of trace elements contained as minerals are involved in the formation of a moisturizing layer of perishable food, and effectively function to prevent drying of cell water and suppress oxidation.

Further, in addition to using a single layer or a laminate of a sheet substrate as it is or as a container, without forming a container, a container or tray formed in advance of an appropriate natural material such as plastic, porcelain, wood or the like is used. The freshness retention and the antibacterial effect can also be exhibited by using an adhesive on the inner bottom surface portion or bonding the impregnated sheet by an appropriate means such as thermal bonding. The freshness retention and antibacterial properties can also be exerted by forming a single layer or a laminate of the impregnated sheet base material into a bag shape and putting fresh food or the like in the bag. When the sheet substrate is a nonwoven fabric, a sheet material such as paper or a foamable sheet, it is molded for a pack with an impregnated substrate, and fresh foods, especially chicken eggs and the like are stored therein. It is effective in keeping freshness of fresh food and suppressing the growth of Salmonella cells.

A treatment liquid was prepared. Next, a cotton non-woven fabric is added to the treatment liquid.
(A basis weight of 40 g / m 2 ), squeezed 100% using a mangle, and dried at 100 ° C. to form a packaging material of the present invention. When the fruits and vegetables are wrapped with the above-mentioned cotton nonwoven packaging material, they do not wilt or discolor for a long time (10 days),
It was effective in keeping freshness. As another method, an impregnated cotton nonwoven fabric was adhered and fixed to the inner bottom surface of a styrofoam container for meat with an adhesive to obtain a drip absorber. As a result, it was possible to absorb the drip, suppress the growth of microorganisms, and further suppress the discoloration of meat, which was effective in maintaining freshness. Further, a test was performed by laminating a polyethylene film having a thickness of 0.02 mm on the impregnated nonwoven fabric, and a similar freshness retaining effect was obtained. On the other hand, the cotton non-woven fabric treated only with "Zeomic AW-10N" (same as above) had the same antibacterial properties, but it withered in a few days in terms of keeping freshness, and kept freshness It was confirmed that there was no effect.
