の感度を鈍（する必要があるが。A method of making the concentration of gas components inside the package different from that of the atmosphere may be a physical method of replacing the inside of the package with an appropriate gas, or a method of sealing a drug inside the package to absorb and remove a specific gas. It may also be a chemical method. For example, in the case of using an oxygen detector as a tampering indicator, it is effective to use a method of purging the inside of the package with nitrogen, a method of enclosing an oxygen scavenger in the package, or a method of using both of these methods in combination. If the oxygen in the pan cage is removed using these methods, if the package is tampered with in some way, oxygen will enter the package from the outside and the oxygen content inside the package will increase. Therefore, the color of the oxygen detector changes and it is possible to determine whether or not it has been tampered with.Needless to say, the sensitivity of the oxygen detector is determined according to the degree of oxygen?IfA that increases within the package due to tampering. If only nitrogen is replaced, oxygen will enter the gas barrier packaging material and enter the container, although it is a trace amount.
It is necessary to desensitize the oxygen detector so that it does not respond to this level of increase in oxygen concentration.

濃度はほとんど増力日しないので、高感度のものを用い

改ざん指示剤として、感湿剤を使用する場合にも、上記
と同様にパッケージ内を乾燥窒素で置換する方法。When using a moisture sensitive agent as a tampering indicator, the inside of the package is replaced with dry nitrogen in the same way as above.

もよい。Actions include a method of enclosing a desiccant or a method of using these in combination. If this package is also tampered with, moisture from the atmosphere will enter the package, the humidity inside the package will rise, and the moisture sensitive agent will change color, making it possible to determine whether or not it has been tampered with. Note that when an oxygen detector or a moisture sensitive agent is used as a tampering indicator, both detect the increase in oxygen and temperature inside the package due to tampering. This is not limited to the case of detecting an increase in the concentration of a component, but it is also possible to seal a specific gas in the package, and when this gas leaks due to tampering, the decrease in concentration can be detected by the color change of the indicator. .

The package 1 is a food 3 placed on a tray 2 wrapped in a flexible gas barrier packaging material, i.e., a sheet 1-4, and the inside is purged with nitrogen during the manufacturing stage. A printed layer 5 of an oxygen detecting agent is applied to the inner surface of the gas barrier sheet 4 so as to be visible from the outside. An explanatory text regarding the color change of the printed layer 5 when the package is tampered with is printed near the printed layer 5. When the package is in a normal state, the inside of the package is in a nitrogen atmosphere with almost no oxygen, and the printed layer 5 has its initial color. However, if some tampering is done, oxygen enters the pan cage and the printed layer 5 changes color. In this way, both the seller and the purchaser can easily determine whether or not tampering has occurred by visually observing the printed layer 5.
