How Bubble Wrap Is Made

Popping bubble wrap is a fascinating idle pass time, is not it? Admit it, a few of your fondest childhood reminiscences are of you popping away at a sheet of the stuff with absorbed interest, proper? 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 for your popping pleasure? Read on to search out out exactly how it’s all done.

First, granules of plastic are carefully sprinkled onto a heated conveyor belt. This warms the plastic grains to a pliable consistency, although they still hold their shape. Think of those bits of plastic like heated chocolate chips; even when they’re hot they still stay the identical shape unless disturbed, at which level they develop into liquid. So the warm plastic grains pass under a roller which squashes all of them flat. During this squashing, the individual bits of plastic get melded together and a thin, clear sheet of plastic emerges on the other side of the roller.

Now, two 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 primary 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 hole, shaping the bubbles by stretching plastic into the dents. This is rather a lot like if you poke you finger right into a taut sheet of plastic wrap and depart a dent.

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

So the subsequent time a big package arrives at your door and also you rip it open to seek out it stuffed with bubble wrap, think back to the factory where that stuffing was made. And while you’re indulging your inner child by enjoying with your noisy improvised toy, bear in mind the simple process that created this wonderfully amusing material. Happy popping!
