Bubble Wrap is a pliable transparent plastic material commonly use for packing fragile items. Regularly spaced, protruding air-filled hemispheres ("bubbles") provide cushioning for precious or breakable items. Bubble Wrap was created by two engineers, Alfred Fielding and Marc Chavannes, in 1957. Like many innovations, it was accidental: The two were trying to create a textured plastic wallpaper with paper backing that could be easily cleaned. The term is a registered trademark of the Sealed Air Corporation (US) which was founded in 1960 by those inventors, and should theoretically only be used for products of that company. However, due to the popularity of the brand, the trademark has been genericized.
