The Balloon Kingdom: All About Balloons!

These things are completely faded and nothing but a thin coating is used to prevent UV light from entering the food when it is packaged to prolong the freshness. Fill one with a lot of air; like a balloon with a little more helium than you then a bright light shines on one side; if you see the light, it will not stop the helium from coming out at all. Nylon LLDPE is used in party balloons.
