Packaging materials are substances used to wrap, protect, and contain products for storage, shipping, and sale. Common types include cardboard, plastic, glass, and metal. These materials help ensure that items remain safe during transportation and reach consumers in good condition. Different packaging materials serve various purposes. For example, cardboard is lightweight and recyclable, making it ideal for shipping boxes, while plastic is often used for flexible packaging like bags and wraps. Glass containers are popular for food and beverages due to their ability to preserve freshness, while metal cans are commonly used for long-lasting storage of products.
