Wooden box vacuum packaging involves placing the goods into a wooden box, removing the air inside the box to reach a predetermined vacuum level, and then completing the sealing process. Vacuum inflation packaging places food into a box, removes the air inside to reach a predetermined vacuum level, then inflates with nitrogen or other mixed gases, and finally completes the sealing process.

Vacuum-packed wooden boxes remove all air from the packaging and use materials with low oxygen permeability, preventing external oxygen from penetrating, thereby reducing the rate of oxidation and rancidity in fresh meat. These boxes naturally extend the shelf life by 5 to 7 days compared to cardboard packaging. However, after vacuum sealing, the oxygen blockage provides corrosion and rust prevention.
