Cling film, also known as plastic wrap or food wrap, is a thin, transparent plastic material used primarily for covering food items. It is made from polyvinyl chloride (PVC) or low-density polyethylene (LDPE) and is designed to cling tightly to surfaces, helping to keep food fresh by preventing air exposure. This versatile product is commonly used in kitchens to wrap leftovers, cover dishes, or protect fruits and vegetables. Its ability to create a seal helps to reduce spoilage and maintain moisture, making it a popular choice for both home cooks and professional chefs.
