Cryotanks Ltd has many years of experience in Modified Atmosphere Packaging (MAP) and gas flushing. 

If you want to preserve your food product, achieve a longer shelf life, while maintaining texture, taste and colour look no further because Cryotanks can accommodate your needs. Regardless of your business size we have a range of tanks that can be installed to provide you with the ideal gas mixture for your food packaging requirements. 

MAP primarily uses 3 gas types: CO₂, Nitrogen and Oxygen, all of which are naturally present within the air we breathe. The CO₂ inhibits the growth of bacteria yeast and mould, while nitrogen is an inert gas that fills the remaining space and prevents collapsing of the package. Oxygen is used to preserve the bright red colour in raw meat and also utilised in some types of white fish or crustations. 

By modifying the atmosphere with a specific gas mixture in the package you naturally preserve the food product hence extending the shelf life and quality. This protective atmosphere preserves the taste, safety, and appearance of the food for longer. For these reasons this commonly makes MAP packaging more advantageous than vacuum or skin packaging, including less product waste due to longer shelf life meaning more money saved for your business.
