How Bubble Wrap Is Made
Popping bubble wrap is an enchanting idle pass time, isn't it? Admit it, some of your fondest childhood memories 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 good little pockets of air are trapped between the plastic just in your popping pleasure? Read on to search out 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, though they nonetheless hold their shape. Think of these bits of plastic like heated chocolate chips; even when they're hot they nonetheless keep the identical shape unless disturbed, at which point they turn out to be 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, two of those sheets are used for making bubble wrap. One has the actual bubbles and the opposite 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. Because 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 a lot like once you poke you finger into a taut sheet of plastic wrap and leave a dent.
Finally, the second sheet of plastic is laid on prime of the first, trapping the air within the bubbles between them. A blast of scorching air seals the two 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 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 find it stuffed with bubble wrap, think back to the factory where that stuffing was made. And while you are indulging your inside child by playing with your noisy improvised toy, remember the simple process that created this wonderfully amusing material. Happy popping!
