Packing materials are substances used to protect and secure items during storage or transportation. Common types include bubble wrap, packing peanuts, and cardboard boxes. These materials help prevent damage from impacts, moisture, and other environmental factors. Choosing the right packing materials is essential for ensuring that items arrive safely at their destination. For fragile items, materials like foam inserts or corrugated cardboard provide extra cushioning. For heavier items, sturdy boxes and strapping tape are recommended to maintain structural integrity during transit.
