Air bubble film packaging, also known as bubble wrap, is a common packaging material used in online sales for several reasons:

• Protection: Air bubble film packaging provides excellent cushioning and shock absorption, helping to protect the item being shipped from damage during transit. It can also help prevent scratches, dents, and other types of damage.
• Versatility: Air bubble film packaging can be used to wrap items of all shapes and sizes. It can be easily cut or folded to fit the shape of the item being shipped.
• Cost-effective: Air bubble film packaging is relatively inexpensive compared to other packaging materials such as foam or molded pulp.
• Lightweight: Air bubble film packaging is lightweight, which helps to reduce shipping costs, especially for items being shipped over long distances.
• Eco-friendliness: Some air bubble film packaging is made from recycled materials and is recyclable, which can help reduce waste and the environmental impact of shipping.

Overall, air bubble film packaging provides a cost-effective and versatile solution for protecting items during shipping, making it an essential component of online sales.
