How Bubble Wrap Was Invented by Accident, As Wallpaper
Imagine two engineers in 1957 sealing shower curtains together, one layered over the other, so that small pockets of air get trapped in between. Alfred Fielding and Marc Chavannes were trying to invent a new kind of textured wallpaper with a modern look. What came out looked much more like packing material, a plastic sheet dotted with air bubbles, than anything you'd stick on a wall.
Fielding and Chavannes themselves weren’t quite sure what to do with it at first. The wallpaper never caught on; after all, most people don’t want walls that burst with every touch. They even tried using the bumpy sheets as insulation for greenhouses, hoping the air pockets might help stabilize temperature, but that idea fizzled too. Yet, those awkward air-filled bumps ended up becoming exactly what they needed, not for decoration, but as a protective layer.
Three years later, in 1960, Bubble Wrap found its true purpose. IBM had just launched its 1401 computers, and the delicate silicon chips inside were prone to breaking during shipping. Fielding and Chavannes pitched their curious packaging to IBM engineers, who spotted what others missed: the floating pockets of air worked better than anything else to absorb shocks. With a new name, Bubble Wrap’s real career as a packaging staple began.
The science behind it is pretty simple. Each bubble traps air inside a thin plastic skin, working like a tiny spring to spread and absorb impact. When pressed, the bubble flexes, soaks up most of the force, and then slowly lets the air out, preventing fragile items from being damaged. Try poking a bubble and you’ll see, nearly all the energy goes into pushing on the gas inside rather than bouncing your finger back.
Modern Bubble Wrap now comes in various cell sizes and sometimes even in unpoppable versions made for efficiency. The basic idea hasn’t changed. An attempt at stylish wallpaper failed, but solving someone else’s problem, getting delicate computer chips to their destination unscathed, gave Bubble Wrap its unique place in the world. It’s funny how an offbeat idea can pop up in just the right spot.
