The food is placed under normal air, and if it is not disposed of in time, it is easily degenerated and easily oxidized. In order to change the conditions in which foods tend to deteriorate under natural conditions, most foods nowadays will use vacuum packaging machines for food processing. Nowadays, vacuum sealers have tended to mature in the process of continuous transformation. In recent years, many domestic advanced brands have stepped out of the international advanced market and established very good results. It bodes well for the development of the domestic industry. It cannot be denied that compared with the advanced level in foreign countries, there is still a big gap in China's sealing machine industry, especially in terms of its technical level. As the level of development continues to deepen, vacuum sealers are also required to pay attention to more and more detailed issues. The most important thing is to be able to control the situation in the market and adjust their own development according to the actual needs of customers. For the domestic sealing machine industry, the domestic good economic development market has brought about a broad market and has laid the foundation for the further development of the industry. Domestic vacuum sealing machine companies should grasp the opportunity, focus on technology research and development and innovation, seize the core, to enhance the level of industry technology, to achieve breakthroughs in innovation, improve the market competitiveness of domestic sealing machine, and become a strong promoter of the further development of the packaging industry. The rapid development of China can be said to be the vacuum sealer industry. Automation and intelligence equal to the emergence of some advanced technologies allow it to have a broader development prospects. It is reported that after the emergence of the vacuum sealer, all the products in the vacuum packaging industry in China have achieved considerable development, especially in the pharmaceutical and food industries. Historical changes have taken place in the quality of production and work efficiency, resulting in potential safety incidents. The greatest degree of change has greatly reduced the occurrence of successive security incidents in the past and brought more powerful protection. With the vacuum packaging machine, food can be placed in the natural state for longer, and no mildew will occur. People can guarantee the safety of food by purchasing items that are so packed. As a part of food, packaging has always occupied a very important position in the production and sales of food. In the past, the domestic level of production was limited, so the packaging of food is generally very simple. Some foods are packaged locally and directly packed with waste newspapers. Some foods are not even packaged. However, the characteristics of food packaging are demanding, so this has also caused food safety and hygiene risks to a large extent. From this we can also see how important food packaging quality assurance is to food.
