Have you ever wondered how foil balloons are made? Well here's a quick explanation...

The NASA Space Mission is accredited for developing the concept and technology for the metalization of plastic sheeting that we use to make foil balloons. Cool right?

These foil balloons are made of polyesters or nylon that has a polyethylene coating on one side and is metalized on the other. Once converted, the foil material is heat sealed, which creates a bag-like product with a valve at the bottom or a BALLOON.

Over simplified but you get the gist.

Something to note...

These balloons are commonly referred to as MYLAR balloons. However, mylar is a trademarked name for a type of polyester film that is registered by DuPont. In fact, balloons are not even made out of this mylar material because of the difficulty in heat sealing it together.

Think of Kleenex. Kleenex is a brand, not a facial tissue. So, when referring to metallized balloons, they're really called FOIL balloons and when needing to blow your nose, you need a TISSUE.
