How Bubble Wrap Is Made
Popping bubble wrap is an enchanting 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 good little pockets of air are trapped between the plastic just on your popping pleasure? Read on to seek out out precisely how it's all done.
First, granules of plastic are intently 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 hot they nonetheless stay the same form unless disturbed, at which level they develop into liquid. So the warm plastic grains pass under a roller which squashes all of them flat. Throughout this squashing, the individual bits of plastic get melded collectively 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 precise bubbles and the opposite acts as a cover to seal the air in. To kind the bubbles, the primary sheet is wrapped around a cylindrical bar with little bubble formed 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 lots like while 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 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 businesses that use this product everyday receive it and package their own items in it to protect them from damage in transit.
So the subsequent time a large package arrives at your door and 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 inner child by playing with your noisy improvised toy, remember the simple process that created this wonderfully amusing material. Happy popping!
