Packing materials are substances used to protect and secure items during transportation or storage. Common types include bubble wrap, foam peanuts, cardboard boxes, and packing paper. These materials help prevent damage from impacts, moisture, and dust, ensuring that products arrive safely at their destination. In addition to protection, packing materials can also provide insulation and cushioning. For example, bubble wrap is often used for fragile items, while cardboard boxes are versatile for various sizes and shapes. Choosing the right packing materials is essential for efficient shipping and storage, contributing to overall customer satisfaction.
