Custom Iron On Patches

How Heat-Seal Backing Works and When to Choose It

The back of an iron-on patch carries a thin layer of thermoplastic adhesive. Heat melts it, pressure pushes it into the weave of the fabric, and as it cools it locks the patch in place. That's why the cool-down matters as much as the heat: move the garment while the glue is still soft and the bond weakens.

Heat-seal backing is the right call when:

• The fabric is cotton, denim, canvas, twill or a cotton-poly blend.
• You want to apply patches yourself, at home, without sewing.
• The garment gets normal home washing rather than industrial laundering.

Choose something else for nylon, rain shells, leather, vinyl and stretchy performance fabrics. Those either can't take the heat or won't hold the adhesive. Sew-on is permanent on all of them, and a removable hook-and-loop backing works when you want to swap patches between vests, bags and caps. Prefer to do the whole thing yourself? Here's how to make an iron-on patch yourself.

Embroidered Iron-On Patches Built to Last

Every patch in this collection starts as embroidery on a twill base, finished with a merrowed or heat-cut border. Thread coverage, twill color and border style all work the same as on our sew-on patches; see embroidered patch construction for the full breakdown.

The adhesive layer is applied after stitching, so it covers the entire back right up to the border. That full coverage is what keeps the edges down. A patch with glue only in the middle lifts at the corners within a few washes.

The one setup cost is a one-time $35 digitizing fee per embroidered design. After it's paid, the stitch file is saved to your account to download any time, and reorders of the same design skip the fee.

Personalized Iron-On Patches for Clothes, Jackets and Bags

Iron-on is the most popular backing for gifts and personal projects because anyone can apply it:

• Jackets and vests: chest patches at 3 to 4 inches, and larger back pieces on denim and canvas.
• Kids' clothes: names on backpacks and jackets, or a fun patch over a worn knee.
• Totes and canvas bags: a quick way to make a plain bag yours.
• Hoodies and sweatshirts: cotton and cotton-poly fleece take heat-seal well. Need the hoodie too? See our hoodies to press patches on.
• Family events and reunions: a matching personalized patch for every relative's jacket or bag, applied at home the night before.

Logo Patches for Staff Tees and Branded Merch

Businesses use iron-on logo patches to brand clothing in house. Keep a stack of patches on the shelf and press one onto a new hire's work shirt, a volunteer's tee or an event jacket when you need it, instead of placing a new order each time.

For branded merch, iron-on patches sell well on their own, too: they're light, cheap to ship and easy for customers to apply. Want your logo printed flat into the fabric instead of sitting on top as a patch? That's a different process; our guide to heat transfer printing explains how it compares.

Household Iron vs. Heat Press Application

With a household iron

1. Set the iron to the cotton setting with steam off. Empty the water tank.
2. Press the garment for a few seconds to remove moisture and wrinkles.
3. Place the patch, then cover it with a thin cotton cloth or parchment paper.
4. Press straight down with firm, steady pressure for 30 to 45 seconds. Don't slide the iron around.
5. Turn the garment inside out and press the back of the area for another 20 to 30 seconds.
6. Let it cool completely flat, then check the edges. Re-press any spot that lifts.
7. Wait 24 hours before the first wash.

With a heat press

A heat press gives even pressure across the whole patch, which is why shops prefer it. A typical starting point is around 330 to 350°F for 15 to 20 seconds at medium-firm pressure, with a protective sheet on top. Lower the temperature for polyester blends.

Caps need a cap press or a curved hat platen, since a flat iron can't press evenly over a structured crown. For those, see our heat-press patches for caps.

Peel-and-Stick and Adhesive Alternatives

Peel-and-stick adhesive patches exist, and they're handy for a single day: a name badge at a conference, a team label at a race, a promo patch at a trade show booth. They aren't built for washing, though, and most fall off in the first cycle.

For anything you'll wear and wash, heat-seal or sew-on is the better choice. For temporary placement you want to reuse, hook-and-loop holds better and lasts longer than sticky adhesive. If your project really calls for stick-on patches, mention it when you order or request a bulk quote.

Upload Your Art, Approve a Proof, Iron It On

1. Upload your artwork: SVG or PDF files are ideal; a 300 dpi PNG or JPG works too, and AI and EPS files can be sent with a bulk quote. A sketch or photo is fine.
2. Pick size, shape and coverage, or tell us what the patch is for and we'll recommend them.
3. Approve your mockup. Nothing is stitched until you say yes.
4. We stitch, back and ship anywhere in the US, or Orlando-metro customers can pick up at our Orlando-area warehouse.
5. You press it on using the steps above.

Frequently Asked Questions

Do iron-on patches stay on through the wash?

Yes, when applied correctly. Press with firm pressure, let the patch cool flat, wait 24 hours, then wash inside out on cold or warm with a gentle cycle and hang dry or tumble low. High dryer heat is what loosens the adhesive over time. For work clothes washed hot every week, add a few stitches around the border.

Can I apply an iron-on patch with a heat press?

Yes, and it's the most reliable method because the pressure is even across the whole patch. A common starting point is about 330 to 350°F for 15 to 20 seconds at medium-firm pressure, with a protective sheet on top. Use a cap press or hat platen for structured hats, and lower the heat for polyester blends.

Will iron-on patches stick to polyester or nylon?

Polyester blends usually work at a lower temperature with a pressing cloth, though some 100% polyester performance fabrics have finishes that resist adhesive. Nylon is the problem fabric: it can melt or glaze before the glue bonds, and coated nylon won't hold it at all. For nylon jackets and packs, choose sew-on or hook-and-loop instead.

Iron-on or sew-on: which lasts longer?

Sew-on lasts longer, often as long as the garment itself, because thread doesn't weaken with heat and washing. A well-applied iron-on patch holds through many washes with gentle care, but adhesive can lift over years. The best of both: iron the patch on to position it, then stitch around the border.

Can I remove an iron-on patch?

Usually, yes. Heat the patch again with an iron or heat press to soften the adhesive, then peel it off slowly from one edge while it's warm. Some residue may remain; pressing a scrap of cloth over it while warm lifts most of it. Delicate or thin fabrics can show a faint mark where the patch was.

Is there a minimum order?

No. You can order a single patch for a gift or a test, or hundreds for a team or business. The one-time $35 digitizing fee applies per design, so per-piece cost falls as quantity rises.
