Popping bubble wrap is a captivating idle pass time, is not 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 perfect little pockets of air are trapped between the plastic just on your popping pleasure? Read on to seek 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 these bits of plastic like heated chocolate chips; even when they are scorching they still keep the identical form unless disturbed, at which point they develop into liquid. So the warm plastic grains pass under a roller which squashes all of them flat. Throughout 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 these 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 gap, shaping the bubbles by stretching plastic into the dents. This is rather a lot like whenever you poke you finger right 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 within the bubbles between them. A blast of scorching air seals the 2 sheets together 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 companies and companies that use this product everyday receive it and package their own items in it to protect them from damage in transit.
So the following time a big package arrives at your door and 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 inside child by playing with your noisy improvised toy, bear in mind the easy process that created this wonderfully amusing material. Happy popping!
