Balloons can add a festive feeling to just about any party or family gathering, and in order to get more bang for your buck, you’re going to want to choose a material that will last. Standard balloons might last for the day, and that’s great if that’s all you’re looking for. But if you want your balloons to last a bit longer, make sure that you purchase Mylar balloons. Mylar is known for its tensile strength as well as its dimensional stability.
Known by other names, the material is sometimes called boPET, or biaxially-oriented polyethylene terephthalate. Because that’s a bit of a mouthful, it is most commonly called Mylar or Melinex. A relatively new material, it has only been around since the 1950s. It was developed by a company known as DuPont and Imperial Chemical Industries. Before it was widely used for commercial reasons, NASA utilized this material in a 1960 and 1964 launch.
