How Bubble Wrap Is Made

Popping bubble wrap is a captivating idle pass time, isn’t it? Admit it, some of your fondest childhood recollections are of you popping away at a sheet of the stuff with absorbed curiosity, proper? In these treasured idle moments did you ever wonder how that bubble wrap is made? Or how these perfect little pockets of air are trapped between the plastic just in 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 scorching they still stay the same form unless disturbed, at which level they develop into liquid. So the warm plastic grains pass under a roller which squashes them all 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, two of those sheets are used for making bubble wrap. One has the actual bubbles and the other acts as a cover to seal the air in. To form the bubbles, the primary sheet is wrapped around a cylindrical bar with little bubble shaped 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 so much like when you poke you finger right into a taut sheet of plastic wrap and leave a dent.

Finally, the second sheet of plastic is laid on top of the primary, trapping the air within the bubbles between them. A blast of hot air seals the 2 sheets collectively right into a single piece and voila! bubble wrap! The factory packages the bubble wrap (no stuffing required there) and ships it off. The many corporations 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 subsequent time a big package arrives at your door and also you rip it open to find it stuffed with bubble wrap, think back to the factory where that stuffing was made. And while you’re indulging your internal child by enjoying with your noisy improvised toy, bear in mind the straightforward process that created this wonderfully amusing material. Happy popping!
