How Bubble Wrap Is Made
Popping bubble wrap is an interesting idle pass time, isn't it? Admit it, a few of your fondest childhood reminiscences 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 in your popping pleasure? Read on to find out exactly 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, though they nonetheless hold their shape. Think of these bits of plastic like heated chocolate chips; even when they're hot they still stay the same form unless disturbed, at which level they turn out to be liquid. So the warm plastic grains pass under a roller which squashes them all flat. Throughout this squashing, the individual bits of plastic get melded together and a thin, clear sheet of plastic emerges on the opposite side of the roller.
Now, of those sheets are used for making bubble wrap. One has the actual 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 shaped 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 so much like once 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 high of the primary, trapping the air in the bubbles between them. A blast of hot air seals the two 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 many corporations and companies that use this product on a regular basis obtain it and package their own items in it to protect them from damage in transit.
So the following 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're indulging your inner child by taking part in with your noisy improvised toy, bear in mind the simple process that created this wonderfully amusing material. Happy popping!
