Air bags, also known as air pillows or inflatable packaging, are a type of packaging material used to protect items during shipping and handling. They are made from thin, flexible plastic material and are inflated with air to create a cushioning effect.

Air bags are commonly used to fill empty space within shipping boxes or containers, helping to prevent items from shifting during transit and reducing the risk of damage. They are also used to wrap and cushion individual items, providing a layer of protection against impact, vibration, and other types of damage.

Air bags come in a variety of sizes and shapes, and can be customized to fit the specific needs of the item being shipped. They can be inflated using a variety of methods, such as manual pumps, electric pumps, or automated systems.

One of the advantages of air bags is that they are lightweight and easy to use, making them a cost-effective and efficient option for protecting items during shipping and handling. They are also reusable and recyclable, making them a more sustainable choice than some other types of packaging materials.
