"Some say...Imitation is the sincerest form of flattery. We're flattered!
But the fact is that Bubble Wrap®, a registered trademark of Sealed Air, is often used incorrectly to describe all air cellular cushioning material. As a trademark, Bubble Wrap® only describes Sealed Air® air cellular cushioning material.
The Bubble Wrap® brand provides the assurance of quality and performance in bubble cushioning offered only by Sealed Air. Bubble Wrap® protective packaging employs a "barrier layer" which retains air...providing superior, longer lasting protection over other brands.
For maximum value specify Bubble Wrap® cushioning from Sealed Air. Ask for the best and accept nothing less."
I found that information at the Sealed Air Corporation's website.
