Answer 1

Solution :-

Wafers and other food products are seal packed in airtight packets because to preserve and to protect them from rancidity.

Wafers and other food products are filled with nitrogen gas. This is done to prevent the food items from oxidising. Oxygen is a very reactive gas and easily combines with other molecules and moisture, causing chemical changes to take place. This makes the food items stale. Nitrogen is less reactive gas than oxygen. Seal packing of the food items in airtight packets helps elongating the shelf life of the food products.
