Uflex, in collaboration with a foreign technology partner, has developed Flexfresh equilibrium modified atmospheric packaging (EMAP), which can extend the shelf life of fresh produce.
Several packaging solutions for fresh produce struggle with a water condensation problem within the pack. As products tend to perspire, modified atmospheric packaging (MAP) is not feasible as a result of higher release of CO2 within the bag.

It is important for fresh produce packaging to have steady oxygen levels to keep the product fresh.
Uflex chairman Ashok Chaturvedi was quoted by the Business Standard saying: "Flexfresh, while maintaining the humidity inside the bag at 98%, keeps the product absolutely dry without allowing condensation of the humidity.
"This results in very low weight loss of the produce as it continues to breathe in hydrated oxygen available inside the bag.
