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

Think of those bits of plastic like heated chocolate chips; even when they are scorching they nonetheless keep the same shape unless disturbed, at which point they turn 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 together 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 other acts as a cover to seal the air in. To type the bubbles, the primary 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 every little gap, shaping the bubbles by stretching plastic into the dents. This is loads like while 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 high of the primary, trapping the air in 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 companies 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 subsequent time a big 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!
