Food packaging in space

Space food is food for astronauts to eat in space flight.

It is understood that the food packaging used by the Shenzhou 12 astronauts is a high-barrier lunch box developed by China.

In order to develop this package, the professional R&D team also developed corresponding multi-layer co-injection equipment, modified atmosphere packaging sealing device, high-barrier sealing film, etc.

Co-injection molding (also known as sandwich injection, co-injection molding) technology applied in aerospace food is a typical case of multi-component injection

Modified atmosphere packaging, also known as MAP or CAP, domestically known as modified atmosphere packaging or replacement gas packaging, inflatable packaging

In addition, the Shenzhou 12 astronauts can stick the lunch box to the bulkhead through Velcro, or obtain the same dining experience as the ground through the adsorption of the card position on the plate

At present, China's aerospace food packaging is divided into different forms such as retort pouch packaging, metal packaging, and composite film packaging according to different raw materials and the processing requirements of Chinese food.
