How do they put the air in the bubble wrap?

that is a beautiful question

lemme guess...you started popping the bubble wrap and mom said stop doing that 🤔

It involves different resin beads being melted together to form a plastic sheet that is then fed onto a huge vacuum roller containing the bowl shaped indentations. As the sheet wraps over the vacuum roller it sucks the sheet into the indentations and the bubble is formed and then heat sealed.

I would think the air is already in there like air is in everything. And the machine just glues or melts the pieces of plastic together.

Science

The plastic is squeezed together which traps the air already present between the layers. Some bubbles have more air than others because of this.

There is a dunnage machine that fills the bubble packs and heat seals it shut.

I'll betcha AndysAttic has the answer to this because I'm sure it has something to do with Creation Science and the Earth being flat! He is a highly exalted university professor in Skegness and he knows pert near everything!

commercial/business bubble wrap machines basically worse like a vacuum sealer in reverse (air pump fills pre-formed rolls with air and hot seals them)
