How do they get the air inside the bubble wrap?

Answer 1

Hmmmm... I'm not one to know, but if you have the Discovery Channel or the Science Channel for cable or sattelite, you can request to show how it's made on "How It's Made". Simply go to http://community.discovery.com/eve/forums/a/frm/f/6941947648 and suggest Bubble wrap as a topic for the next show. It doesn't cost a dime, and it's kinda cool seeing what you suggested on TV -- That is, if you want a visual representation as well. for a verbal one:

"Bubble Wrap manufacturing starts as polyethylene resin, in the form of beads about the size of pea gravel. The beads go into an extruder - a long cylinder with a screw inside that runs its entire length. As the screw is turned, heat builds up and the resin melts into a liquid that is squeezed out of the cylinder into two stacked sheets of clear plastic film. One layer of the film is wrapped around a drum with holes punched in it, and suction is applied drawing one web of film into the holes that form the bubbles. The second layer of film is then laminated over the first so that when the two films are joined, they stick together and trap the air in the bubbles."

P.S. No offense, but this isn't the best place to put this question. I'm just saying, for next time. You get better answers and less criticism for putting it in the wrong catagory. =)
