Packaging materials are essential for protecting and preserving goods during shipping and storage. CELLOPHANE is a thin, transparent material made from cellulose that is often used to wrap food and other items. TAPE is a strong adhesive material used to secure packages and boxes. TWINE is a type of string or cord made from natural fibers such as cotton or hemp, and is often used to tie packages together. Saran is a type of plastic wrap used to cover food and other items to keep them fresh. All of these materials are important components of packaging and help ensure the safe delivery of goods.
