い。2. Description of the Related Art Deodorizing agents for removing offensive odor gases, freshness-retaining agents for maintaining freshness of fruits and vegetables by removing gases such as ethylene generated from fruits and vegetables, and gas treatment agents for removing harmful gas components in the atmosphere Has been proposed and is widely used in practice. These gas treating agents are usually in the form of powder or granules, and when used, they are often used in a container or in the form of a pack filled in an air-permeable bag.

る。On the other hand, as a matter of course, it is preferable that the removal rate of the harmful gas components in the atmosphere is as fast as possible. For example, in the case where fruits and vegetables are packed and stored in a container, it is necessary to remove ethylene generated from fruits and vegetables as quickly as possible in order to suppress a decrease in freshness due to ethylene. However, the above-mentioned pack-like shape has a local effect, and it is difficult to quickly apply the effect to a wide range. This is a problem common to all gas treating agents for removing deodorants and other harmful gases.

可能となる利点がある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sheet-like gas treating agent in order to solve the above problems of the gas treating agent. By making it into a sheet, it is possible to cover the entire target such as fruits and vegetables, and it is possible to quickly exert an effect in a wide range. Further, there is an advantage that the object can be wrapped and various other usage methods are possible.

ある。Various types of such gas treating agent sheets have been proposed in the past, but the original performance is deteriorated when the sheet is processed, or the performance is not sufficient in the first place, and the gas treating agent sheet is not suitable for practical use. At present, there is no suitable one.
In view of the above situation, the present invention is to provide a sheet-like gas treatment agent having a sufficient harmful gas removing ability.

Obtained. A polyester non-woven fabric (50 g / m 2 ) (Gare type air permeability of about 0 seconds / 100 ml of air) was used as a sheet base material, and the above paste liquid was uniformly sandwiched between the two sheets by a coater roll. .. This was passed through a drying furnace, heat-treated, dried and melted to obtain a sheet-like gas treating agent. The amount of immobilized gas treating agent is 300 g / m 2 . The obtained sheet was cut into a size of 10 cm × 15 cm, and this was cut into 100 ppm hydrogen sulfide and 100 ppm trimethylamine.
