Balloon arches are decorative structures made from inflated balloons arranged in an arch shape. They are commonly used for events such as weddings, parties, and corporate functions to create a festive atmosphere. The arches can be customized in various colors and sizes to match the theme of the event. These arches are typically constructed using a frame, which can be made from materials like PVC or metal, to support the balloons. Once the frame is in place, balloons are attached, often using a technique called balloon tying or by using balloon clips. Balloon arches can serve as backdrops for photos or as entryways to enhance the overall decor.
