Mylar balloons, also known as foil balloons, are a popular choice for parties and celebrations. They are made from nylon with a metallic coating, which gives them a shiny, reflective surface. Mylar balloons can be easily designed in different shapes, sizes, and colors, making them a versatile decoration option. They can be inflated with either helium or air, and helium allows them to float in the air.
Compared to latex balloons, Mylar balloons typically last longer because they are made of a plastic polyester material that creates an airtight and nonporous environment, preventing the helium from escaping. Latex balloons, on the other hand, are more flexible and thinner once inflated.
Its worth noting that in geometry, a mylar balloon is a surface of revolution that maximizes volume for a given generatrix arc length). However, this is not the same as the Mylar balloons commonly used for parties and celebrations.
