Iron on Patch

An embroidered patch is an embroidered design on firm backing that is applied to clothing by organizations to distinguish membership or rank, by youth groups to mark accomplishments, and by individuals for art or expression
Iron-on, heat seal, and sew-on are the three most common types of patches. Iron-on can be created by applying heat from a household iron, but heat seal requires a professional machine. Both heat types melt the thermoplastic glue and adhere it after drying, but heat seal requires the higher temperature and pressure of a professional heat press machine. Sew-on patches can be applied with fabric glues or sewn on. Other backings include rubber, magnet, velcro, and sticky. Sticky backing using something comparable to 'double sided sticky tape' and is often chosen when the badge application is temporary (such as at business conferences).
