When you need to pack fragile items of irregular shapes, much like this expensive flower vase, you need cushioning for its specific shape. 
In such cases, using bubble wrap is not the most suitable and efficient option. That's when you turn to Expanding Foam Bags. 
These are an easy-to-use solution, requiring absolutely no machines, and prove to be extremely cost-effective for sellers and packers who have to transport huge quantities of expensive fragile items.
An expanding foam bag works by holding the product firmly in its place, and taking the actual outer shape of the product so that it sits snugly in its outer packaging.
