Sterile packaging: The sterilized food is packaged in a sterile environment and sealed in a sterilized container, so as to obtain a longer shelf life without preservatives and refrigeration.
Moisture-proof packaging: divided into two categories. One is to prevent the loss of moisture in packaging, the other is to absorb moisture in packaging. The former prevents moisture from being discharged from the packaging through high barrier packaging materials, while the latter can be repackaged with high moisture absorption material - desiccant.
