A retractable banner, also known as a roll-up banner or pull-up banner, is a portable display commonly used for advertising and marketing purposes at events, trade shows, conferences, retail stores, and various other locations. It typically consists of a flexible graphic panel that is attached to a spring-loaded roller mechanism housed in a base. The banner can be easily pulled up from the base and secured in an upright position for display, and then retracted back into the base for storage and transportation. Retractable banners are popular due to their ease of use, portability, and ability to quickly set up and take down for different events or promotions. They come in various sizes and designs to suit different marketing needs.
