How Bubble Wrap Is Made

Popping bubble wrap is a captivating idle pass time, isn’t it? Admit it, a few of your fondest childhood recollections are of you popping away at a sheet of the stuff with absorbed interest, 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 for your popping pleasure? Read on to find out precisely 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 these bits of plastic like heated chocolate chips; even when they are sizzling they still keep the identical form unless disturbed, at which level they develop into liquid. So the warm plastic grains pass under a roller which squashes them all flat. During this squashing, the person bits of plastic get melded together and a thin, clear sheet of plastic emerges on the other side of the roller.

Now, of these sheets are used for making bubble wrap. One has the precise bubbles and the other acts as a cover to seal the air in. To form the bubbles, the first sheet is wrapped around 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 leave 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 scorching air seals the 2 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 various firms and businesses that use this product everyday obtain it and package their own items in it to protect them from damage in transit.

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