There are many reasons as to why snack and food packets need to be filled with air and all of them are for the good of our consumers. That is, it helps preserve the quality, freshness and taste of the food. It is a difficult matter to make the snack taste just like it was just cooked. The main problem of snacks and food is oxygen and humidity inside the packet that change its taste and shorten its life. This is the main reason why manufacturers must fill snack and food packets with air. After knowing the reason, we shall look into the components of snack and food packets, by examining the two parts, which include:
1.Plastic film used to manufacture the packet. The snack and food packets are made of various plastic film types. Each type has different qualities for air and vapor insulation. Because of this, manufacturers use different types of plastic to make the packet airtight so that the food maintains its freshness and taste. However, when months have passed, regardless of how well the seal is, air and vapor may still enter the packet.
2.Gas added into the packet. This is not ordinary gas or air. Because air contains oxygen, if we were to add oxygen into the packet, the snacks and food inside would spoil more quickly. The gas added is Nitrogen because it does not react to other molecules, and therefore helps maintain the food condition. Before adding Nitrogen, air must be sucked out first. All this helps preserve the freshness and taste of the food for as long as possible.
Another reason behind adding Nitrogen gas is to reduce the breaking of snacks and food inside during transportation when packets may be thrown around. It helps absorb the force of collisions. No seller wishes to deliver broken snacks or food to their consumers.
With all the above reasons, snacks and foods packets are normally put in inflated bags. Consumers who read this are sure to understand the reasons behind this as consumers of appealing-looking snacks and foods are the ones who benefit the most.
