Modified Atmosphere Packaging (MAP)

A proven way to effectively extend the shelf life of your packaged food products

Are you looking to preserve your food product naturally? Do you want to achieve a longer shelf life, while maintaining texture, taste and colour. Could you improve production planning, reduce product waste and better meet the expectations of your customer?

Modified Atmosphere Packaging (MAP) or gas flushing is a proven and natural method of extending the shelf life and quality of food products. It uses a specific single gas or a mixture of gases to create a protective atmosphere around the food. This protective atmosphere, combined with appropriate packaging material and, in many cases, lowered temperatures, preserves the taste, safety and appearance of the food for longer.

With decades of experience in MAP, we have run numerous product tests and built knowledge about the ideal gas mixture for each food type. Whatever your business size, our experts look forward to helping you along the way, from identifying the best gas mixture for your product to getting you started up.

​Why Choose MAP Rather than Vacuum or Skin Packaging?

Shelf Life

The vast majority of the products achieve a longer shelf life with MAP than with vacuum or skin packaging

Waste Reduction

Longer shelf life means reduced food waste

Product Appearance

Soft, uneven products may suffer from the vacuum process leaving their shape less attractive to the end user

Cost Savings

Less product lost means more money saved

Which Gases Are Used In MAP And Why?

MAP involves mainly the use of three gases naturally present in the air that we breathe: CO², Nitrogen and Oxygen. Have a look at this short video with our UK expert Jon Trembley to find out why.

"What should I declare on the label if I'm using food grade gases to package my product?"
If you use MAP you will need to state 'packaged in a protective atmosphere' on the label (Regulation (EU) 1169/2011).
