With the growing demand for fresh and healthy food options amongst consumers, suppliers are in need of a way to meet this demand. Traditionally, preservatives and other chemicals have been added to foods to increase the shelf life of products. However, customers have become more conscious of these chemicals and the possible effects on their bodies. This is where modified atmosphere packaging comes into play.

Some of the advantages of using MAP over other packaging technologies include:

  • Longer shelf-lives for products
  • Better product quality
  • Greater product availability
  • Reduced need for preservatives
  • Smaller amounts of product and package waste

What Is Modified Atmosphere Packaging (MAP)?

Many of the spoiling issues that occur to perishable food and beverage products—e.g., discoloration, flavor or textural changes, and microbial growth—can be attributed to the presence of oxygen. Modified atmosphere packaging (MAP)—also known as reduced oxygen packaging—is designed to increase the shelf life of these goods by modifying the internal packaging conditions to promote greater product stability and longevity.

Using this technology, a mixture of pure oxygen, carbon dioxide, and nitrogen is introduced into the packaging process. This mixture extends the shelf life of fresh products and helps to maintain the visual appeal, texture, and nutritional benefits of the food.

How Does Modified Atmosphere Packaging Protect Food?

In contrast to other packaging methods, MAP protects perishables from both external and internal factors that promote product damage or degradation. The modification of the internal environment can occur either passively or actively. Passive MAP operations use specially selected packaging materials that encourage the natural development of the desired environmental conditions through the respiration of the contained products and the diffusion of gases into and out of the packaging. Microperforated top seal film is an example of this method. Active MAP operations replace the existing gas composition with a more desirable mixture (usually consisting of pure oxygen, carbon dioxide, and nitrogen). Both methods mitigate product spoilage without the addition of preservatives or other chemicals.

Many consumable goods benefit from MAP, including:


  • Bakery: With proper packaging involving vacuum sealing or Modified Atmosphere Packaging (MAP), bakery items like sandwiches, cakes, and desserts can be preserved for anywhere from two-and-a-half weeks to seven months
  • Dairy: Milk and its derived products spoil easily without proper packaging. They must be protected from oxidation through MAP and perfect sealing.
  • Meat: Raw meat and processed meat products lose color and flavor as they spoil. More importantly, spoilage may lead to food poisoning through bacterial contamination. It is important to use cutting-edge MAP to preserve meat products.
  • Produce: Proper packing with MAP extends the shelf life of fruits and vegetables. It also preserves their freshness and nutritional value.
  • Snacks: Various types and shapes of packaging are necessary for snacks. Thermoformed containers, cups, and trays sealed with film are great for packaging snacks.

Point Five Packaging’s MAP Packaging Machines & Materials

Point Five Packaging is a full-service food packaging and modified atmosphere packaging (MAP) system supplier. We offer the following packaging systems:

Tray Sealers

Tray sealers ensure products are fully protected from external contaminants. Compared to manual sealing methods, they reduce the amount of time and labor needed to complete sealing operations.

Vacuum Chambers

Vacuum chambers allow for the formation of airtight seals. In doing so, they help maintain product freshness, prevent freezer burn, improve product flavor, and/or reduce storage requirements.

High Barrier Films

High barrier films help to retain the flavor, texture, and appearance of a variety of foods including meat, poultry, seafood, fresh fruits and vegetables, and more. These films are both oven and microwave safe, have a high and low gas barrier, and are perfect for prepared food that is roasted, steamed, boiled, or cooked in the packaging. They are high-clarity and possess anti-fog characteristics so the food inside stays visible to consumers.

Why Use a MAP System?

You should consider a MAP system for your products because of the cost savings and consumer benefits. With selling fresh foods comes the risk of spoilage and any product the spoils cannot be sold. A MAP system extends the shelf life of your products. Second, once customers know that your products do not contain preservatives or other chemicals, they will be more likely to purchase from you.

The initial investment into a MAP system will easily be recouped through less spoiled product and more sales due to extended shelf life and an increase in purchases from conscious buyers.

Modified Atmosphere Packaging Systems (MAP)  significantly extend product shelf-life while maintaining appearance, texture and freshness without the use of a vacuum.
