Guide on Nitrogen Flush Packaging
 An appropriate packaging gas is required to store and transport sensitive products such as food. A 
modified atmosphere environment that inhibits unwanted chemical reactions such as oxidation and 
food spoilage can help you in achieving a better shelf life of the food products. But, the question 
that stands here is which gas can be flushed for food packaging? Here is where nitrogen steps in!
 You must be thinking why only nitrogen? It is because the main component causing food spoilage 
and oxidation is oxygen. If oxygen is flushed into any of the packaging's then the food inside will 
undergo chemical reactions that will directly affect the flavor and texture of the packaged item.

 Moreover, nitrogen acts as an antioxidant component which means it can prevent food from 
undergoing chemical reactions and various climate changes. Nitrogen flushed packaging is the 
process of filling nitrogen gas in the pack instead of oxygen to meet advantages like high-quality 
food for a long duration, enhanced shelf-life, and high durability.
 As one of the best Gas Flushing Packaging Manufacturer, we at Solos Polymers provide the best-
flushed packaging solution as we believe in customer satisfaction, we see through the customer’s 
perspective.
How Does Nitrogen Flushing Food Packaging 
Works?
 At first, the food container including the product in it is positioned into the empty container of the 
gas filling machine. After that, the machine is used to extract out the oxygen gas present in there 
and fill it with the nitrogen gas.
 The gas flushing machine seals the food container before the flushed gas comes out. At last, these 
nitrogen flushing food packaging is packaged in large boxes and is ready to be shipped or stored 
in the grocery stores.
 Take a note that the nitrogen gas filled in during packaging remains in the container until and 
unless the consumers open it. As soon as the container is opened, the surrounding environment is 
again filled with 78% nitrogen and 21% oxygen as usual. Also, once the container is opened the 
food starts deteriorating and the oil of the product goes rancid.
How to Determine Required Nitrogen for Keeping 
the Food Fresh?
 For simplifying the determination of required gas, here are the main three types to be taken into 
consideration.
1) Type of Food Product :-
 Food products including fruits and vegetables (type 1)undergo oxidation quickly, whereas dry 
food products like beans and more (type 2) have a longer shelf-life. Thus, type 1 requires more 
nitrogen than type 2.

2) Type of Storage :-
 Here storage refers to the surrounding. If you want to store the food products in a cold 
refrigerated page then less nitrogen would work, but if you want to store it in a warm or normal 
environmental environment then the packaging should have more nitrogen gas.
 Nitrogen Flushing pouches offer a higher barrier from all environmental conditions to the product 
inside the packet. so that you can enhance the shelf life of your products because nitrogen does 
not react with the products as the oxygen does.

3) Type of Packaging :-
 No matter how appropriately is the procedure carried out! But a breakage or leaking pores can 
ruin the whole work. Therefore, it is necessary to check the packaging containers. A container 
with breakage and a porous surface will leverage the filled nitrogen to the mixed environment.
 There are many more factors that are to be taken into consideration, but these three types were 
the major ones. We as a gas flushing packaging manufacturer & supplier ensures every aspect 
by testing the product to provide the finest solution to our clients.
