Certain types of packaging are designed to protect products during transportation and storage. For example, cardboard boxes are commonly used for shipping items because they are lightweight and sturdy. They can be easily stacked and are recyclable, making them an eco-friendly choice. Another type of packaging is plastic wrap, which is often used to keep food fresh. It creates an airtight seal that prevents moisture and air from getting in, helping to extend the shelf life of perishable items. This type of packaging is convenient and widely used in both households and commercial settings.
