2. Description of the Related Art Mushrooms are packed in a packaging bag such as mushrooms, which are provided in a sealed manner, and by using a packaging tray, such as shimeji mushrooms, mushrooms are stored in a tray and synthesized. There is a resin film that covers the opening surface of the tray and seals it. In either case, a material having a high oxygen and carbon dioxide permeability is used to maintain the freshness of the mushroom. It should be noted that the packaging material is not only required to have a high permeability to oxygen and the like, but is required to have a permeability to oxygen and carbon dioxide for the purpose of preventing the generation of aerial hyphae such as shimeji. Gas permeability needs to be set. The material of the above-mentioned packaging tray is also determined in consideration of the permeability of oxygen and the like.

Since packaging materials such as trays pose a problem as waste in the packaging of shimeji etc., packaging in bags without using trays has been studied. However, in the case of such bag packaging, it is necessary to solve the material problems such as the oxygen permeability of the packaging material as described above and the bag strength problem such as the shape retention of the product packaged in the packaging bag. is there. As a method for solving these problems, the present applicant has proposed a method of using a packaging material having a two-layer structure in which a film excellent in permeability of a gas such as oxygen and a film excellent in strength are laminated (Japanese Patent Application No. 2000-242242). No. 3-67905).

The above-mentioned packaging material having a two-layer structure can satisfy both the strength of holding the breathable saw as a packaging bag while keeping its shape, and the packaging is sealed by heat welding. It has the characteristic of being easy to use from the point of view of work, but it has a problem in manufacturing the packaging material that the film must be adhered because it has a two-layer structure, and it uses a material with good breathability. Even in such a case, however, there is a problem in that the air permeability varies depending on the thickness of the laminated film and the air permeability of the packaging material is limited by the film used.

For example, a polystyrene film is often used as a synthetic resin film having excellent oxygen and carbon dioxide permeability in a mushroom packaging bag. The polystyrene film has a thickness of 25 μm and an oxygen permeability of 4000 cc / m 2 .24 hr.atm. ,
The carbon dioxide permeability is 2400cc / m 2 .24hr.atm and the water vapor permeability is 35 to 45g / m 2 .24hr.0.1mm. These gas permeability can be used without any problem as a packaging bag for mushrooms. The polystyrene film is excellent in gas permeability but inferior in heat-welding property, so that it cannot be directly used as a mushroom packaging bag. Generally, the packaging material for mushroom packaging has an oxygen permeability of 1000-4000cc / m 2 .24hr.atm.
Something is used. However, higher gas permeability is desired when the cloudiness of the packaging bag after packaging becomes a problem, or when the mushroom is prevented from becoming uneven and the mushroom freshness is more effectively maintained.

As described above, the conventional mushroom packaging bag satisfies the required conditions such as gas permeability, but further improvement is required in terms of gas permeability. The mushroom packaging bag according to the present invention has been studied as a solution to these problems, and has better breathability and moisture permeability than the conventionally used packaging materials, thereby maintaining the freshness of mushrooms. It is an object of the present invention to provide a mushroom packaging bag that can achieve a high level of the conditions required for a mushroom packaging bag, such as excellent product shape retention, and excellent heat-welding property.

In the packaging bags of these examples, a synthetic resin film is used as a material to form the bag. However, as described above, the synthetic resin film is used to seal the mushrooms and ensure the required air permeability. It is characterized by using a ventilation hole treatment film provided with ventilation holes. FIG. 4 is an explanatory view showing the cross-sectional structure of the vent hole treatment film. The vent hole treatment film 20 is characterized in that the synthetic resin film 22 is provided with a large number of non-penetrating vent holes 24 that stop within the thickness of the film as shown in the figure. The ventilation hole 24 is formed by laser light irradiation, corona discharge, or the like.
It is possible to appropriately control the depth and the number of the vent holes 24 formed per area.

The air permeability of the synthetic resin film varies depending on the thickness of the film used, and the air permeability increases as the film thickness decreases. Vent holes 2 in the film as described above
In the case where No. 4 is provided, the thickness of the film becomes thin at the vent hole 24 portion, so that the air permeability is improved and the air flow rate is increased. Since the depth and the number of the ventilation holes 24 per area can be adjusted, the ventilation hole treated film 20 can be provided in accordance with a required ventilation amount by appropriately adjusting these.

The above-described vent hole treatment film 20 has a feature that it can be easily provided as a material having the necessary air permeability as described above, and also has a high air permeability which cannot be obtained by the conventional synthetic resin film. It has the characteristic that it can be obtained as a material. For example, the polystyrene film described above has excellent gas permeability,
According to the above-described vent hole-treated film, it is possible to easily obtain a film having an oxygen permeability of about 10 times greater than the conventional one. In addition, the air permeability is 1,000 to 5,000 cc / m, which is similar to conventional packaging materials in relation to film thickness.
It is also possible to obtain a film having about 2 .24Hr.Atm performance.

In the case of the above-mentioned vent hole treated film, the air permeability is not improved by reducing the thickness of the film, so that the air permeability can be improved without lowering the strength of the film. Therefore, it is effective in that it can be provided as a packaging bag having a required shape retention property with a single-layer packaging material.

Further, since the above-mentioned vent hole treatment film is provided with the vent holes 24 in the synthetic resin film 22 to adjust the air permeability, even a synthetic resin film having low air permeability is used as a packaging material having suitable air permeability. It becomes possible to do. For example, polypropylene is excellent in terms of film transparency, heat-welding property, and anti-fog function,
Although there is a problem in that it is inferior in breathability, it is possible to provide a packaging material having excellent breathability by subjecting the film to the treatment of providing ventilation holes as described above. This packaging material has excellent breathability in addition to anti-fogging property, heat-welding property, etc.
Mushroom freshness can be suitably maintained, and it can be provided as a mushroom packaging bag with high commercial value.

The mushroom packaging bag prepared by using the ventilation hole-treated film 20 obtained as described above is provided as a bag having a required permeability of oxygen, carbon dioxide or the like, so that the mushroom is kept in a fresh state. Can be held at. Actually, conditions such as suitable oxygen permeability vary depending on the type of mushroom, and for example, shimeji mushrooms having too high oxygen permeability should be limited to a certain degree of air permeability because aerial hyphae are generated, On the other hand, for enoki mushrooms, it is preferable that the air permeability is high and it is possible to prevent a peculiar odor.

Further, since the packaging material is provided as a material obtained by subjecting a single layer synthetic resin film to a ventilation hole treatment, it is not necessary to bond the synthetic resin film to be laminated and the packaging material can be easily manufactured. . In the production of the packaging bag, the conventional production method of the packaging bag can be used as it is. For example, in the case of the product shown in FIG. 1, a long body of a synthetic resin film having a vent hole treatment is folded in two in the middle, It can be manufactured by heat sealing at a predetermined interval and cutting at the heat sealing portion.
