Linde is a global leader in hygienic design and has more experience in IQF food technology than any other freezer manufacturer.

Linde MAPAX® modified atmosphere packaging systems seal in freshness to extend shelf life. The MAPAX system from Linde successfully inhibits the deterioration of food in a natural way — by combining the correct gas mixture , film and packaging equipment, to keep products fresh and appetizing and help reduce returns due to spoilage.

Ideal for trayed, bagged and pouched products, the MAPAX modified atmosphere packaging system can extend the practical shelf life of fresh foods typically by 200% or more compared to packaging in air. For example, the shelf life of raw red meat can typically be extended from 2-4 days to 5-8 days (at <38°F), and cakes from several weeks to up to one year. (See comparison chart below.)

This extended shelf life can provide other important benefits for food processors:

Improved Distribution

Goods protected by the MAPAX technology can be delivered across longer distances or on a less frequent basis for enhanced logistical flexibility. From the delivery of raw materials to the transportation of food products, the MAPAX solution can:

  • Reduces the amount of preservatives
  • Extends geographical boundaries and time of preservation

New Food Products, Improved Recipes and Marketing

  • Allows processors to include more delicate ingredients
  • Allows the creation of new dishes and products
  • Allows highly attractive and marketable packaging
