Popping bubble wrap is a fascinating idle pass time, isn’t it? Admit it, some of your fondest childhood memories 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 excellent little pockets of air are trapped between the plastic just for 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, though they still hold their shape. Think of these bits of plastic like heated chocolate chips; even when they’re hot they still keep the same shape unless disturbed, at which level they grow to be liquid. So the warm plastic grains pass under a roller which squashes all of them flat. During 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, of these 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 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 a lot like when you poke you finger 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 sizzling 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 firms and companies that use this product everyday obtain it and package their own items in it to protect them from damage in transit.

So the next time a big package arrives at your door and also you rip it open to find it stuffed with bubble wrap, think back to the factory the place that stuffing was made. And while you are indulging your inside child by playing with your noisy improvised toy, keep in mind the straightforward process that created this wonderfully amusing material. Happy popping!
