Popping bubble wrap is a fascinating idle pass time, is not it? Admit it, some of your fondest childhood recollections 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 good little pockets of air are trapped between the plastic just to your popping pleasure? Read on to search out out precisely how it’s all done.
First, granules of plastic are carefully 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 are scorching they still stay the identical form unless disturbed, at which point they change into 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 other side of the roller.
Now, two of those sheets are used for making bubble wrap. One has the precise bubbles and the opposite 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 formed 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 so much like when 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 primary, trapping the air in the bubbles between them. A blast of sizzling air seals the two 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 numerous firms and businesses that use this product everyday receive 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 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 internal child by playing with your noisy improvised toy, keep in mind the easy process that created this wonderfully amusing material. Happy popping!
