Bubble mailers should not be confused with bubble wrap although both are types of product packaging. Bubble mailers are plastic bags which are made up of different layers of plastic. Between each layer, or sometimes there are two layers laid on top of each other to form the sides of the product packaging bag, is a bubble of air that cannot escape because it’s sealed within the layers. The air bubble serves as a protective cushion that shields the contents of the product packaging from any sudden impacts or movement that could shock the contents and damage these.
