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.

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.

[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.

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.

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

According to the present invention, it is possible to obtain a natto bag that has both air permeability and sealability, has no water absorption, can be used with an automatic bag making and filling machine, can be easily printed clearly, and has appropriate rigidity. . 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.

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.
