Popping Bubble Wrap after it has served its protective packaging purpose might be satisfying, but just how is the trapped air product made?

From there, the film is vacuumed down and the air is trapped. Finally, the film goes through other rollers and cools, forming a bond so that the product has a flat backing with a bubbled topping.
