                     HOW DOES NICHROME'S 
MAP TECHNOLOGY WORK?
INTRO
MAP or 
Modified Atmosphere Packaging is a 
widely used technique of preservation 
when it comes to food packaging. 
MAP technology like that in a 
tray sealing machine is gaining more 
and more popularity as a method of 
preserving freshness and lengthening 
the shelf life of fresh foods - fruits, 
vegetables, meat, dairy products and 
more.
SO WHAT IS MAP TECHNOLOGY?
Atmospheric air is a combination of 3 elements - N2 (79%), O2 (20.96%), CO2 
(0.04%) and traces of inert gases and vapour.
MAP packaging, sometimes known as controlled atmosphere packaging, is the 
method of modifying the makeup of the internal atmosphere of a package using a 
modified atmosphere packaging machine - usually food packages and medicines - 
in order to improve the shelf life of the packed products.
This technology was developed to deal with the short shelf life of certain food 
products such as meat, fish, poultry and dairy in the presence of oxygen.
It is plainly obvious that a reduction in oxygen and its replacement with more 
suitable gases can deter or reduce oxidation reactions and microbiological spoilage.
MAP food packaging using a MAP tray sealer generally involves the lowering of the 
amount of oxygen in the headspace within the package. Nitrogen - a comparatively 
inert gas - or carbon dioxide can be used to replace oxygen.
The use of active techniques such as gas flushing and compensated vacuum, or 
passive ones like designing ‘breathable films’ can be used to achieve a stable 
atmosphere of gases inside the packaging.

HOW DOES MAP CONTROL MICRO-ORGANISMS?
MAP can control 4 types of MAP for shelf-life and food Factors that influence 
micro-organisms: spoilage: shelf-life
