How Bubble Wrap Is Made
Popping bubble wrap is an enchanting 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, 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 find 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're hot they still keep the identical form unless disturbed, at which level they grow 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 collectively 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 opposite 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 shaped indentations in it. Because the plastic is held taut on the cylinder, suction pulls it into every little hole, shaping the bubbles by stretching plastic into the dents. This is quite a bit 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 first, trapping the air in the bubbles between them. A blast of sizzling air seals the two 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 businesses 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 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 where that stuffing was made. And while you are indulging your inner child by enjoying with your noisy improvised toy, bear in mind the simple process that created this wonderfully amusing material. Happy popping!
