Modified Atmosphere Packaging (MAP): Redefining Freshness in the UK and Ireland.


In the realm of food packaging, where innovation meets sustainability, Modified Atmosphere Packaging (MAP) stands out as a pioneering solution. For those unfamiliar with this term, let’s delve into the intricacies of MAP packaging and its profound impact on the UK and Ireland’s fresh produce sector.

What Does MAP Stand For in Packaging?

MAP stands for Modified Atmosphere Packaging. At its core, MAP involves altering the composition of gases within a package to extend the shelf life of perishable products, especially fresh produce. By controlling the levels of oxygen, carbon dioxide, and also nitrogen, MAP creates an environment that inhibits microbial growth and slows down the natural degradation processes of food items.

Advantages of Modified Atmosphere Packaging Packaging:

  1. Extended Shelf Life. One of the primary benefits of MAP is its ability to prolong the freshness and quality of products. By adjusting the gas composition, MAP ensures that perishables remain fresh for longer durations, reducing food waste in the process.
  2. Enhanced Product Safety. With reduced oxygen levels, MAP packaging minimises the risk of aerobic bacterial growth, thereby enhancing the safety and hygiene of the packaged products.
  3. Improved Visual Appeal. MAP helps in retaining the vibrant colours and textures of fresh produce, ensuring that consumers receive products that not only taste fresh but also look appealing.
  4. Optimal Storage & Transportation.  The controlled atmosphere within the packaging safeguards items from external contaminants and physical damage.

MAP vs. CAP Packaging: What’s the Difference?

While both MAP (Modified Atmosphere Packaging) and CAP (Controlled Atmosphere Packaging) revolve around altering the internal gas composition of packages, they serve slightly different purposes:

  • MAP: Primarily focuses on extending the shelf life of products by adjusting the atmosphere. It is widely used for a variety of perishables, including fruits, vegetables, and meats.
  • CAP: Goes a step further by not only modifying the atmosphere but also maintaining it at a constant level throughout storage and transport. CAP is often used for long-term storage of produce.

Is Modified Atmosphere Packaging  Sustainable?

The sustainability of packaging solutions is a pressing concern, especially in today’s environmentally conscious era. MAP packaging, when executed correctly, can indeed be sustainable:

  • Reduced Food Waste. By extending the shelf life of products, MAP helps reduce the volume of wasted food, aligning with global sustainability goals.
  • Optimised Resource Use. MAP packaging typically uses materials efficiently, ensuring minimal waste during production. Moreover, the prolonged shelf life reduces the need for frequent replenishments, thereby saving resources in the supply chain.
  • Recyclability. Many MAP packaging materials are recyclable, further enhancing their eco-friendly credentials.
