  • Patent number: 11603629
    Abstract: A container and a preparation method thereof are provided. A material forming the container includes at least two types of oxidized nanocelluloses interlaced with each other, the at least two types of oxidized nanocelluloses being configured to have different degrees of expansion after absorbing moisture in a same environment. In a dry condition, the at least two types of oxidized nanocelluloses do not expand, so the structure of the container is relatively dense and the air permeability is poor, which can sufficiently maintain moisture of an article stored in the container. In case the article itself or other reasons cause high humidity, different oxidized nanocelluloses of the container expand after absorbing moisture, so that gaps between different oxidized nanocelluloses becomes larger, and the air permeability of the container becomes better, which can discharge excessive moisture, enabling the container to self-adjust the air permeability based on humidity.
