Saran is a type of plastic wrap commonly used in kitchens to cover food items. It is made from a polymer called polyvinylidene chloride (PVDC) or polyethylene, which makes it flexible and clingy. Saran helps keep food fresh by creating a barrier against air and moisture, preventing spoilage. Originally developed in the 1940s, Saran has become a household staple for food storage. It is often used to wrap leftovers, cover dishes, or protect food during cooking. The product is known for its transparency, allowing users to see the contents without unwrapping it.
