Nitrogen Flushing and Sealing Machines are for partially evacuating the pouch and filling it with an inert gas like nitrogen. The contents in the pouch will have longer shelf life by reducing fungal and bacterial growth due to reduced presence of oxygen. Inert gas filling helps to prevent crushing of contents. Items like chips, wafers, mixtures, fried nuts, coffee etc. can be packed in this machine for retaining its freshness and aroma till it reaches the consumer.
