Reasons why we need modified atmosphere preservation box
Products packed in a modified atmosphere box can reduce the external impact and ensure the integrity.
1.Strong preservation function
The tight and sturdy modified atmosphere box after sealing can block the penetration of water and oxygen.It’s dust-proof and moisture-proof and can be put into the refrigerator for long-term refrigeration, which well protects the freshness of the ingredients.

Fresh-keeping packing: antioxidant, antibacterial | No packing:fast oxidation speed |
2.Long shelf life
The modified atmosphere box generally adopts vacuum quick cooling and antibacterial treatment, which can effectively control microbial contamination and recontamination, prevent food oxidation and prolong the shelf life of food.

Modified atmosphere packing box can prolong the shelf life of ingredients from one day to more than seven days
Strong impact resistance at low temperature
After being frozen at -7°C for several hours, the product can still maintain excellent performance, meet sensory requirements, operational performance and other physical and chemical indicators and will not become brittle when impacted.

Attention should be paid to the selection of packing materials
- The packing box should be made of high-barrier material and the boxed film may vary according to the characteristics of different products.
- The packing box should be highly effective in terms of moisture permeability, oxygen permeability and light permeability.
-The common features of packing films are anti-fogging and minimum light permeability. Products of different air permeability should select films of different properties.If the respiration of fruits and vegetables affect the proportion of mixed gases, the gas ratio must be balanced by relying on the gas permeability of the barrier film
Storage enviroment
The best storage environment for modified atmosphere packing is refrigeration. At present, the temperature of refrigerated food in supermarket refrigerated display cabinets is about 33% higher than 7°C, and about 5% is higher than 13°C. The average temperature of household refrigerators is 10 to 13°C. Obviously, the current cold chain conditions cannot meet the refrigerated temperature and condition requirements of refrigerated food of modified atmosphere packing or vacuum packing. The recommended refrigeration temperature for many non-breathing refrigerated fresh foods (such as livestock, poultry and fish) is 0-2 °C, and the recommended refrigeration temperature for many breathing refrigerated fresh foods (such as apples, strawberries, mushrooms) is 0-5 °C. The ambient temperature of storage also directly affects the preservation effect of food.
