Check the patch's backing material and test with heat
Iron-on patches have a shiny, plastic-like backing that melts when heated. To confirm, place a thin cloth over the patch and press with a hot iron for 15-20 seconds. If the patch adheres to fabric, it's iron-on. Alternatively, look for a smooth, glossy underside rather than a rough or fabric backing.
Identifying iron-on patches by appearance
- Shiny, plastic-like backing material
- Smooth underside (not rough or fabric)
- May have manufacturer's iron-on instructions printed on paper backing
Testing methods for iron-on patches
- Heat test: Press with iron through cloth for 15-20 seconds
- Adhesion check: See if patch sticks to fabric after heating
- Visual inspection: Look for glossy backing material
