Popping bubble wrap is a fascinating idle pass time, is not it? Admit it, a few of your fondest childhood memories are of you popping away at a sheet of the stuff with absorbed curiosity, right? In these treasured idle moments did you ever wonder how that bubble wrap is made? Or how these excellent little pockets of air are trapped between the plastic just in your popping pleasure? Read on to find out precisely how it’s all done.

First, granules of plastic are intently sprinkled onto a heated conveyor belt. This warms the plastic grains to a pliable consistency, though they still hold their shape. Think of these bits of plastic like heated chocolate chips; even when they’re hot they still stay the same form unless disturbed, at which point they turn out to be liquid. So the warm plastic grains pass under a roller which squashes all of them flat. Throughout this squashing, the individual bits of plastic get melded collectively and a thin, clear sheet of plastic emerges on the opposite side of the roller.

Now, of those sheets are used for making bubble wrap. One has the precise bubbles and the opposite acts as a cover to seal the air in. To form the bubbles, the first sheet is wrapped round a cylindrical bar with little bubble formed indentations in it. As the plastic is held taut on the cylinder, suction pulls it into each little gap, shaping the bubbles by stretching plastic into the dents. This is loads like while you poke you finger into a taut sheet of plastic wrap and go away a dent.

Finally, the second sheet of plastic is laid on top of the first, trapping the air in the bubbles between them. A blast of hot air seals the two sheets together into a single piece and voila! bubble wrap! The factory packages the bubble wrap (no stuffing required there) and ships it off. The numerous firms and companies that use this product on a regular basis receive it and package their own items in it to protect them from damage in transit.

So the following time a large package arrives at your door and also you rip it open to search out it stuffed with bubble wrap, think back to the factory where that stuffing was made. And while you are indulging your interior child by enjoying with your noisy improvised toy, keep in mind the straightforward process that created this wonderfully amusing material. Happy popping!
