What is "cling film"?

Cling film, also known as plastic wrap or cling wrap, is a thin, transparent plastic film used for wrapping and covering food items. It is designed to cling tightly to surfaces, creating an airtight seal that helps preserve the freshness of the food and prevents moisture loss. Cling film is commonly used in the kitchen for wrapping sandwiches, covering bowls or plates of leftovers, and storing perishable items in the refrigerator or freezer.
