How Bubble Wrap Is Made

Popping bubble wrap is an enchanting idle pass time, is not it? Admit it, some of your fondest childhood memories are of you popping away at a sheet of the stuff with absorbed interest, right? 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 for your popping pleasure? Read on to seek out out exactly 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 those bits of plastic like heated chocolate chips; even when they are scorching they still stay the same shape unless disturbed, at which point they turn out to be liquid. So the warm plastic grains pass under a roller which squashes them all 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, 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 kind the bubbles, the first sheet is wrapped round 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 lots like when 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 top of the first, trapping the air in the bubbles between them. A blast of hot 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 corporations and companies 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 next time a large package arrives at your door and also you rip it open to find 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 simple process that created this wonderfully amusing material. Happy popping!
