1. Why is a bag of chips full of air?
Let’s get one thing straight – it is NOT because the companies want to show that the packet is full of chips.
And it isn’t air – it is mostly Nitrogen.
It is called a slack fill and the manufacturers use this “air” to keep the product fresh and protect it against damage during transportation and handling. If there was no air, you would get soggy and spoilt chips. You don’t want soggy and spoilt chips, do you?
