Modified atmosphere packaging is a technique that uses gas flushing to reduce oxidation, which can cause discoloration, off-flavors, and spoilage. The film is also designed to keep out ambient gases and moisture, which double up its preservation efforts.

The importance of nitrogen in manufacturing is well known. Despite its high value, this gas has been underused. Traditionally, industries only used nitrogen for cleaning and drying purposes.

In the age of globalization, the demand for efficient and cost-effective products has increased. As a result, it has become important to produce nitrogen gas on-site to meet this demand. In addition, generating nitrogen on-site will reduce the need for external suppliers.

A PSA nitrogen generator works by injecting a high pressure nitrogen gas into a tank. The air passes over an adsorbent that inhibits the formation of nitrogen gas.
