Food safety has always been a matter of great concern to people's livelihood in China. In recent hot events, the worrying food safety and hygiene situation of online celebrities' shops has been frequently exposed, and the reporter's unannounced visit is only the tip of the iceberg.

In addition to raw materials, machinery and equipment in contact with food are also part of the source.
Food machinery can be divided into two categories: food processing machinery and packaging equipment. The seals in food machinery are generally in direct or indirect contact with food, so the cleanliness and safety of these products must be guaranteed, and the materials used must meet the requirements of food grade.

Any product must be labeled as "food grade", and it must meet the requirements of national food safety standards in addition to its own requirements.
