〔産業上の利用分野〕
本発明は蒸煮した大豆に納豆菌を添加した納豆原料の充
填、密封、熟成および流通が衛生的かつ効率的に行われ
る納豆袋に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a natto bag in which natto raw materials made by adding natto bacteria to steamed soybeans can be filled, sealed, ripened and distributed hygienically and efficiently.
従来、納豆は大別すると、藁つと、発泡ポリスチレン容
器、袋などに納豆菌と共に充填し、40℃前後の室(む

共に雑菌を排除しがたい。通気孔を穿設した発泡ポリス
チレン容器も充填効率があまり高いものではなく、一般
に嵩張り取扱いやすいものではなかった。Conventionally, natto can be roughly divided into straw, foamed polystyrene containers, bags, etc., filled with natto bacteria, placed in a room at around 40°C to ripen, and then sold commercially. Although straw has been used for a long time, it does not allow efficient filling, is bulky, and is difficult to eliminate bacteria. Expanded polystyrene containers with ventilation holes also do not have very high filling efficiency, and are generally bulky and not easy to handle.
最も取扱いやすい包装形態は袋詰である。特に紙とシー
ル性にすぐれたポリオレフィンとを積層−した複合紙は
、自動包装充填機を使用することができ、きわめて生産
性の高いものである。The easiest packaging format to handle is bagging. In particular, composite paper in which paper and polyolefin with excellent sealing properties are laminated can be used with automatic packaging and filling machines and has extremely high productivity.
納豆容器として求められる特性は、第1に納豆菌の繁殖
に必要な酸素を供給するために通気性が不可欠である。The first characteristic required for a natto container is air permeability in order to supply the oxygen necessary for the propagation of natto bacteria.
第2に自動製袋充填機を使用し、生産効率を向上させる
ためにヒートシールが可能である。第3に納豆が水分を

ないことである。第4にある程度の剛性が要求され、第
5に印刷しやすい素材であることが要求される。Second, an automatic bag-filling machine can be used and heat-sealed to improve production efficiency. Thirdly, since natto is a food that contains water and tends to be unhygienic, it is not hygroscopic. Fourthly, a certain degree of rigidity is required, and fifthly, the material must be easy to print on.
従来の納豆袋は上記条件の中、通気性を得るためにポリ
オレフィン層に設けた穿孔があるため、吸湿性素材であ

り、製品としては更にこの袋を他の袋に密封しなければ
ならない。Under the above conditions, conventional natto bags have perforations in the polyolefin layer to achieve breathability, so the paper, which is a hygroscopic material, absorbs moisture and becomes wet, making it unhygienic. must also seal this bag with another bag.

い温度に設定することである。[Means for Solving Problems] and [Operation] The present invention provides a nonwoven fabric obtained by intertwining polyolefin short fibers with at least one other type of plastic short fibers having a melting point higher than that of the polyolefin. It is characterized by producing bags from a paper-like material obtained by melting the polyolefin short fibers by heating to a temperature above the melting point and below the melting point of other plastics, or from a paper-like material laminated with a heat-sealable film with pre-perforated holes thereon. shall be. That is, a nonwoven fabric made by intertwining two or more types of short plastic fibers with different melting points is subjected to heat treatment, and the temperature at this time is set to a temperature where some of the fibers melt and some of the fibers do not melt. It is to set.
その結果、熔融した繊維が溶融しない繊維を強固に固定

ましくは20℃以上である。Examples of the polyolefin with a low melting point according to the present invention include low density polyethylene with a melting point of about 100 to 150°C, polypropylene with a low polymerization rate, and the like. Plastics with higher melting points include polypropylene, nylon, high-density polyethylene, and polyester. The difference in melting point between a polyolefin with a high melting point and a plastic with a low melting point is 10°C or more, preferably 15°C or more, and more preferably 20°C or more.

できる。Any method can be used to make these fibers into a non-woven fabric, but the paper-like material of the present invention can be easily obtained by mixing the fibers into a slurry in water and running it on a normal paper machine. It is obtained by heating to a temperature higher than the melting point of the higher melting point polyolefin and lower than the melting point of the higher melting point plastic. In addition, commercially available special paper A

調整することができる。Furthermore, by laminating a heat-sealing film made of polyolefin such as low-density polyethylene or low-polymerization degree polypropylene having a melting point of about 100 to 150°C on this paper-like material, the heat-sealing performance can be further improved. Laminating such films impedes air permeability, but if perforations are provided in advance in the heat sealing film, air permeability can be adjusted appropriately.

Furthermore, since the short fibers of the film obtained using a paper machine are arranged in almost a fixed direction, it is possible to open natto bags using only the force of the fingers, which improves productivity. An excellent and easy-to-handle natto bag can be obtained.

た。Ultra-fine short fibers of low-density polyethylene with a melting point of 120°C and ultra-fine short fibers of polypropylene with a melting point of 165°C were mixed with water to form a slurry, and the slurry was passed through a paper machine to obtain a film-like nonwoven fabric. This nonwoven fabric was passed through a hot roll set at a temperature of 145°C to obtain a paper-like film of the present invention. The air permeability of this paper-like film was approximately 50 sec/1 nchφ/100 cc oxygen. Water did not pass through it, and due to the characteristics of polyolefin, it was not hygroscopic, so it was possible to print clearly on the surface.
