Have you ever opened a pack of chips and felt cheated after finding out that most of it was filled with air? It is a general belief that companies put air in the packet to make it look bigger and heavier. But this is not the case. The gas that is inside the chips packet is there for a reason. So let’s find out why companies put gas in the packets of chips and which gas they use.
While it’s a common misconception that the chips packets are filled with oxygen, but it is not true. They are actually filled with Nitrogen, and it is done for very important reasons.
The first reason is self-explanatory. Gas is filled in the packet of chips to prevent the breaking of chips during transportation and handling. To overcome the breaking problem, Pringles started to sell their chips in a can.
The reason for using nitrogen instead of oxygen is that oxygen is very reactive. If chips bags were filled with oxygen, bacteria will grow quickly in it. Also, oxygen can cause moisture inside the packet. The use of nitrogen ensures that chips will remain crispy and bacteria free.
According to Eat Treat, a packet of Lays is filled with 85% nitrogen. Uncle Chips and Bingo Mad Angles are filled with 75% nitrogen, while Taka Tak and Kurkure have 30% and 20 % nitrogen respectively.
