Invented in 1960 by American Mark Savannah. At first I just wanted to design a new three-dimensional wallpaper. One day, when he was flying on a plane and saw clouds outside the window, he felt that the clouds were used to protect the plane from landing safely. Inspired by this, he created plastic bubble wrap. Bubble film has quickly become a popular packaging material due to its shock-proof, moisture-proof, and abrasion-proof properties. Later, because many people liked to pinch the bubbles on the bubble wrap, bubble wrap was given the function of relieving psychological stress. Today, the American Sealed Air Company, the patent owner of bubble film, has more than 17,000 employees in 52 countries and regions, and earns more than 4 billion US dollars in revenue from bubble film every year.
