In general, unlike other processed foods, fermented foods have many difficulties in commercializing because they cannot utilize technologies applied to general food packaging, such as sterilization and airtight packaging.

For example, when storing or distributing fermented foods such as kimchi at home, the container packaging them must be sealed to prevent the contents from leaking outside during handling.

In addition, the contents must not be splashed when the lid of the packaging container is opened while the internal pressure is increased by the gas generated during the fermentation process, and must be maintained in a state that meets the fermentation conditions.

Regarding the 'fermented food packaging container' that can satisfy the above conditions, an application has been previously filed under Republic of Korea Patent Publication No. 10-2014-0026936 (publication date: 2014.03.06.).

Specifically, conventional fermented food packaging containers allow gases generated from fermented food packaged inside to be discharged to the outside to prevent leakage of contents due to food fermentation or deformation of the packaging container during the storage process.

However, in most cases, the airtightness of conventional fermented food packaging containers is drastically reduced once the packaging container is opened, even though gas generated inside the packaging container can be discharged to the outside.
