Accordion Fold refers to a method of folding a sheet of material, such as paper or cardboard, into a series of alternating parallel folds that resemble the bellows of an accordion. This type of fold creates multiple panels that can be expanded or compressed, making it ideal for packaging inserts, brochures, and some types of retail packaging.
 
In packaging, the accordion fold is used to maximize space by compacting information or material into a smaller, more convenient form, which can be expanded when needed. It’s commonly employed for multi-page inserts, instruction manuals, and promotional materials, and provides an organized way to present detailed content without needing multiple sheets.
