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, though they still hold their shape. Think of these bits of plastic like heated chocolate chips; even when they’re scorching they nonetheless keep the identical form 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 individual bits of plastic get melded collectively and a thin, clear sheet of plastic emerges on the other side of the roller.
Now, 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 type the bubbles, the first sheet is wrapped around a cylindrical bar with little bubble formed indentations in it.

This is a lot 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 first, trapping the air within the bubbles between them.

The various 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 next time a large package arrives at your door and 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 inner child by playing with your noisy improvised toy, remember the straightforward process that created this wonderfully amusing material. Happy popping!
