MAP Packaging: What it is, how it works and what it delivers

Anyone working with fresh food wants products to remain as fresh, durable, and appealing as possible. One method commonly used is MAP packaging. MAP stands for Modified Atmosphere Packaging, which means packaging under a protective atmosphere. But what does this actually involve, and why should you use it?

What is MAP Packaging?

In MAP packaging, the air inside a package is replaced with a specific gas mixture, typically oxygen (for red meat), carbon dioxide, and nitrogen. By adjusting this ratio to the product (such as meat, fish, cheese, or fresh produce), the growth of microorganisms and oxidation is slowed. This keeps the product fresh for longer without the need for artificial preservatives.

What Are the Benefits?

  • Longer shelf life without quality loss

  • Reduced waste, both in the supply chain and at the consumer level

  • Better presentation, as the product retains its taste, color, aroma, and texture

  • More sustainable packaging, especially when combined with recyclable or cardboard trays

Which Products Are Suitable for MAP Packaging?

MAP packaging is widely used for:

  • Ready meals and convenience foods

  • Meat and poultry

  • Fish and seafood

  • Cheese and dairy products

  • Fresh produce: potatoes, vegetables, and fruits

  • Vegetarian and plant-based products

MAP packaging is suitable for both artisanal processors and industrial producers.

How Does MAP Packaging Work in Practice?

MAP packaging can be applied in various packaging formats, such as flow pack, thermoform, or tray seal packaging. The most suitable format depends on the product, desired shelf life, and production capacity. We highlight two methods for introducing a protective atmosphere into the packaging (skin and vacuum packaging will be covered in one of our upcoming blogs):

Gas Flushing
In gas flushing, the air inside the package is displaced by a gas mixture. This results in a very low residual oxygen level, which is beneficial for products such as soups, sauces, chicken breast, fish, and minced meat.

Advantages:

  • Higher packaging speed

  • Less complex machine setup

  • Lower energy consumption compared to vacuum and gas injection (no vacuum pump needed)

Vacuum and Gas Injection
In this method, a vacuum is first created to remove all air from the package. Then the desired gas mixture is added. This achieves a very low residual oxygen level, which is ideal for products such as rice, pasta, bread, and pastries.

Advantages:

  • Optimal shelf life

  • Minimal oxygen presence

  • Suitable for products where quality and freshness are crucial

The choice between these two techniques depends on your product characteristics, shelf-life goals, and desired production capacity.

MAP Packaging with Sismatec

Since 1963, Sismatec has been active as a supplier of process and packaging machines. As an exclusive partner, we provide Proseal tray sealers. While many suppliers require vacuum to achieve low residual oxygen levels, Proseal often achieves the same results using gas flushing alone, even in complex applications such as the ready meal industry. In addition, we supply Belca flow packers and Webomatic thermoformers, which are ideal for MAP packaging. Our solutions are reliable, fast, and easy to integrate into existing production lines.

What Sismatec Offers:

  • Tailored advice for your product and production capacity

  • High-quality machines from top brands such as Proseal, Webomatic, and Belca

  • Complete line solutions, including weighing, dosing, and automation

  • Test facility in Almelo to explore and test packaging possibilities

  • Service and support with our own technicians and 24/7 availability

Whether you are packaging meat, vegetables, cheese, or ready meals, we provide a solution that works.
