How Bubble Wrap Is Made

 

Popping bubble wrap is a fascinating idle pass time, isn't it? Admit it, a few of your fondest childhood reminiscences 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 good little pockets of air are trapped between the plastic just in your popping pleasure? Read on to search out out exactly how it's all done.

 

 

First, granules of plastic are closely 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 hot they still stay the same form unless disturbed, at which level they become 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 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 actual bubbles and the other acts as a cover to seal the air in. To form the bubbles, the first sheet is wrapped round a cylindrical bar with little bubble formed indentations in it. Because 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 loads like once you poke you finger into a taut sheet of plastic wrap and go away 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 hot 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 various corporations 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 following time a large 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, keep in mind the easy process that created this wonderfully amusing material. Happy popping!
