Modified atmosphere packaging, or MAP, is an innovative technique that extends the shelf life of perishable foods. It works by changing the gases surrounding the food inside the packaging. MAP helps keep food fresher for longer, reducing waste and making it more convenient for consumers. The modified atmosphere packaging technology of SPG Pack sets a new standard in food packaging, delivering unparalleled freshness and safety to consumers worldwide.


MAP method involves altering the atmosphere inside the package to slow down the deterioration of the product. It works by changing the gases surrounding the food inside the packaging.

The principle behind MAP lies in controlling the composition of gases such as oxygen, carbon dioxide, and nitrogen surrounding the product. Typically, oxygen is removed and replaced with a mix of gases like nitrogen and carbon dioxide. This slows down spoilage caused by oxygen exposure, like fat breakdown in meats, and microbial growth.

How does it Work?

In this technology of SPG Pack, the atmosphere inside the package is adjusted to create an optimal environment for the specific food product. Oxygen levels are typically reduced to slow down oxidative reactions, which are responsible for food deterioration such as browning and flavor loss. Meanwhile, the level of carbon dioxide is often increased to inhibit the growth of spoilage microorganisms and pathogens. Additionally, nitrogen may be added to displace oxygen and maintain package pressure, preventing product compression and extending shelf life.

Advantages of Modified Atmosphere Packaging Method

Modified atmosphere packaging (MAP) offers several advantages over traditional packaging methods, particularly for perishable foods. Here are some key benefits:

To Slow Down the Spoilage

This method slows down the spoilage process, thereby preserving the freshness, color, texture, and nutritional value of the food for a longer duration compared to traditional packaging methods.

Reduced Waste

With extended shelf life, the modified atmosphere packaging technology of SPG Pack helps reduce food waste throughout the supply chain. This benefits producers by minimizing spoilage and allowing consumers to enjoy their food longer.

Environmentally Sustainable

This method benefits consumers by ensuring fresher and safer food. It also contributes to environmental sustainability by reducing the carbon footprint associated with food production and transportation.

Easy to Customize

The versatility of SPG Pack’s modified atmosphere packaging method allows for customization according to the specific requirements of different food products. It ensures optimal preservation and quality maintenance throughout the supply chain.

Useable for all Food Sectors

This technology helps preserve the taste, texture, and appearance of food. This is because it slows down natural degradation processes which occur during storage.

More Natural Approach

MAP can sometimes replace the need for chemical preservatives. This will appeal to consumers who prefer a more natural approach to food preservation.

Offers More Choices

Extended shelf life through the MAP method of SPG Pack allows for broader distribution of perishable goods. This opens up new markets for producers and offers consumers a wider variety of fresh food choices.

Product’s Visual Appeal Enhancement

This packaging method often maintains a clear view of the product, allowing consumers to see its freshness and quality. This can enhance the product’s visual appeal and encourage purchase.

Ensures the Product’s safety

It inhibits the growth of spoilage microorganisms and pathogens. The MAP method helps to reduce the risk of foodborne illnesses and ensures the safety of the products throughout their shelf life.

Final Words

In conclusion, the Modified Atmosphere Packaging (MAP) method of SPG Pack is a significant advancement in food preservation technology. It is commonly used for several perishable foods, including fresh fruits and vegetables, meat, poultry, seafood, bakery products, and ready-to-eat meals. As the demand for fresh, convenient, and sustainable food products continues to grow, MAP is ready to play a crucial role in meeting the evolving needs of consumers and the food industry.
