How Bubble Wrap Is Made

Popping bubble wrap is an interesting idle pass time, is not it? Admit it, some of your fondest childhood reminiscences are of you popping away at a sheet of the stuff with absorbed curiosity, 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 to your popping pleasure? Read on to find out precisely how it’s all done.

First, granules of plastic are closely sprinkled onto a heated conveyor belt. This warms the plastic grains to a pliable consistency, although they still hold their shape. Think of those bits of plastic like heated chocolate chips; even when they’re sizzling they still stay the identical shape unless disturbed, at which point they become liquid. So the warm plastic grains pass under a roller which squashes them all flat. During 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 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 first sheet is wrapped round a cylindrical bar with little bubble formed indentations in it. Because the plastic is held taut on the cylinder, suction pulls it into every little gap, shaping the bubbles by stretching plastic into the dents. This is rather a lot like whenever you poke you finger 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 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 companies 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 big package arrives at your door and also you rip it open to search out 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, bear in mind the straightforward process that created this wonderfully amusing material. Happy popping!
