Cling film, also known as plastic wrap, is a thin, flexible, and transparent film primarily used for sealing and preserving food items. Made from materials like polyvinyl chloride (PVC) or low-density polyethylene (LDPE), it adheres tightly to surfaces, creating an airtight seal that helps retain freshness, prevent contamination, and extend the shelf life of food. Commonly used in households, restaurants, and food industries, cling film is ideal for covering containers, wrapping sandwiches, or protecting produce. Its stretchability and ability to cling without the need for adhesives make it a convenient and versatile solution for everyday food storage and hygiene
