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?

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 those bits of plastic like heated chocolate chips; even when they’re sizzling they still stay the identical shape unless disturbed, at which level they change into liquid. So the warm plastic grains pass under a roller which squashes all of them flat. Throughout 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, two 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 first sheet is wrapped around a cylindrical bar with little bubble formed 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 quite a bit like if you poke you finger right into a taut sheet of plastic wrap and depart a dent.
Finally, the second sheet of plastic is laid on prime of the first, trapping the air within the bubbles between them. A blast of scorching air seals the 2 sheets together 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 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 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 inner child by enjoying with your noisy improvised toy, remember the straightforward process that created this wonderfully amusing material. Happy popping!
