How air gets into the bubble wrap…

You know those moments when you think of those really vital questions? It came to me last week in a very quiet place that I won’t name. We all know that film whose popping amuses young and old alike: bubble wrap, which ideally protects fragile products during transport. But how does the air get into the bubbles?

It’s basically as simple and effective as…

…the protective function of the film itself. The plastic that makes up the film is melted at 200 degrees Celsius. In this molten state, it is poured onto a wide roll, the surface of which is treated as a negative mould with indentations the size of later bubbles. When the mass is poured onto the roll, the plastic forms a flat film. The hot plastic mass is sucked through the pits by means of a vacuum so that a depression is formed in the film at this point. Now it’s just a matter of sealing the air in these depressions. This is done by simply placing a second layer of smooth film over the moulded film. Because of the high temperature, the foils will fuse together permanently.

So it’s just like us humans: bursting with love and fusing for eternity.
