Aseptic packaging: packaging sterilized food in a sterile environment and sealing it in sterilized containers to achieve a longer shelf life without adding preservatives or refrigeration.

Moisture proof packaging: divided into two categories. One is to prevent packaging items from losing moisture, and the other is to prevent packaging items from absorbing moisture. The former uses high barrier packaging materials to prevent moisture from being discharged from the packaging, while the latter can add high moisture absorbing materials - desiccants - to the packaging.

Steaming bag: a bag made of flexible composite materials that contains food. After packaging the food in the bag, it is sterilized for a short time in a high-pressure reactor. Before consumption, the bag can be heated in boiling water.

Transparent packaging: A packaging in which all or part of the contents can be seen through transparent packaging materials.

Shrinkage packaging: A packaging method in which a product or packaging is wrapped in shrink film and then heated to shrink the film tightly around the product or packaging.

Vacuum packaging: A packaging method in which a product is placed in an airtight packaging container, and the air inside the container is extracted to achieve a predetermined vacuum degree in the sealed container.

Inflatable packaging: A packaging method in which products are placed in airtight packaging containers and the original air in the container is replaced with gases such as nitrogen and carbon dioxide.

Quick freezing packaging: A packaging that uses freeze resistant and moisture resistant packaging materials and quick freezing technology to allow the frozen contents to be stored for a longer period of time under refrigeration conditions.

Chain clamp self sealing bag: a plastic film bag that can be repeatedly sealed and opened through the protrusions and grooves at the opening after filling or removing the contents.

GMP: The production quality management standard issued by the US Food and Drug Administration, which is known as the production quality management standard for pharmaceutical packaging printing materials in China.

Mouth packaging bag: By adding a hard mouth of high-pressure polyethylene (HDPE) with a cap to the packaging bag (usually a self-supporting bag). According to the different installation positions, it can be divided into upright installation and inclined installation.
