Modified Atmosphere Packaging (MAP) is an innovative technology that uses custom-made polymers to package individual fresh produce. Since the physiological processes of fresh products differ considerably from each other, MAP designs customized packaging solutions for each product. 

The key to modified atmosphere packaging technology is to achieve a balanced state between the concentration of oxygen and carbon dioxide within the packaging where the products are safely packaged.

The MAP of fresh fruits delays the ripening process due to the modified environment within the package. It also reduces the weight loss of products during transportation due to modified humidity. Other benefits of modified atmosphere packaging include preserving the firmness and smooth texture of fruits and vegetables. 

It also reduces cold injuries due to low temperatures. Modified atmosphere packaging technology is very useful in cases where the shipping and storage time of fresh produce must be extended due to unforeseen circumstances. Overall, MAP is a high-end packaging technology that can be adopted to reduce supply chain losses for fresh produce retailing.

MAP technology

Specially designed polymers are used for modified atmosphere packaging. Once the products are sealed, the oxygen concentration inside the packaging decreases due to the respiration of the product, while the carbon dioxide concentration increases. 

This process continues until an equilibrium state between oxygen and carbon dioxide is obtained. Simultaneously, the humidity inside the packaging also increases due to the perspiration of the product, which in turn helps the products stay fresh while preventing their loss of weight and nutrition.

MAP to extend service life

It is scientifically proven that MAP can store fresh produce for up to two weeks at 10-12 ° C (50-54 ° F) without losing its fresh quality.
