Popping bubble wrap is a fascinating idle pass time, is not it? Admit it, a few of your fondest childhood recollections 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 good 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 intently sprinkled onto a heated conveyor belt. This warms the plastic grains to a pliable consistency, although they still hold their shape. Think of these bits of plastic like heated chocolate chips; even when they are scorching they still stay the same shape unless disturbed, at which level they grow to be liquid. So the warm plastic grains pass under a roller which squashes them all flat. Throughout this squashing, the person 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 form the bubbles, the first 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 hole, shaping the bubbles by stretching plastic into the dents. This is lots like while you poke you finger into a taut sheet of plastic wrap and depart a dent.
Finally, the second sheet of plastic is laid on top of the primary, 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 firms and businesses 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 subsequent time a big package arrives at your door and you rip it open to seek out it stuffed with bubble wrap, think back to the factory the place that stuffing was made. And while you are indulging your internal child by playing with your noisy improvised toy, keep in mind the simple process that created this wonderfully amusing material. Happy popping!
