Hot-Peel Film
A PET carrier engineered to release the print while the shirt is still warm, so a production line moves in seconds instead of minutes.
Short version, straight from the floor.
Hot-peel film is a PET carrier sheet that has been coated so the printed ink layer releases from it while the sheet is still hot off the press platen. In practice that means five seconds after the buzzer, the operator grabs a corner and pulls the film off in one motion. The shirt goes into the folding stack.
Peeling at 30 seconds instead of 5. Hot-peel is a hot-peel window, not a hot-peel wait. Once the film cools below about 180 F the release coating relocks. If you get pulled off the press by a phone call, walk it back to the press, hit it for 3 seconds, and peel immediately.
Peeling straight up instead of at an angle. Straight-up peel loads the ink layer in tension. Ink chunks come off with the film. Angle the pull toward yourself at about 30 degrees; the peel front does the release work, not the whole sheet at once.
Storing rolls next to a heater or in a truck. The release coating cures at heat. If a roll gets to 130 F in the back of a delivery van in July, the coating pre-triggers and the film will refuse to release cleanly at press time. Store climate-controlled, sealed until use.
Reusing carrier for a second press. Hot-peel carrier is one-and-done. The release coating is consumed in the first peel. Re-pressing with a spent carrier scorches the shirt and does not re-transfer ink.
A production-floor definition, not a spec-sheet lift.
Hot-peel film is a PET carrier sheet that has been coated so the printed ink layer releases from it while the sheet is still hot off the press platen. In practice that means five seconds after the buzzer, the operator grabs a corner and pulls the film off in one motion. The shirt goes into the folding stack. The next shirt goes on the platen. That five-second peel is where DTF earns its production math.
It works because the release coating is a thermoset that softens at the same temperature the hot-melt adhesive is finishing its bond to the fabric. The ink stays with the fibers, the film comes away clean, and the finish is a soft matte with a bit of texture you can feel with a fingernail. That texture is the tell for hot-peel. Cold-peel comes off glossy. Hot-peel comes off matte.
Every ready-to-press transfer Golden DTF ships out of Long Island runs on hot-peel by default. It is faster on our press line, it survives shipping better because the film is thinner, and it is the film that most heat-press operators are already muscle-memoried into. The one place we swap to cold-peel on purpose is when a customer wants a glossier finish on a black shirt or when they are pressing on stretch fabric where the hot pull can distort the design.
If you have pressed hot-peel before and had it not release cleanly, the answer is almost always temperature. This film wants 300 to 310 F on cotton and cotton blends. Below 295 F the release coating never fully softens and the film fights you. Above 320 F the ink starts to yellow the whites and scorch the fabric. Set the press, hit the button, wait twelve seconds, peel in one motion at roughly a 30-degree angle.
Every field you need before the press cycle starts.
The numbers below come from our own production floor, not a supplier tech sheet. If a field says 305 F, it is because we press at 305 F and it works. If a field says "avoid on tri-blend," it is because we ruined a run and stopped doing it.

Press recipe

- Dwell
- 10 to 12 seconds
- Pressure
- Medium-firm (about 40 psi)
- Peel window
- 3 to 8 seconds after press, still warm
- Peel angle
- 30 degrees, single motion
Application
- Fabric compatibility
- 100% cotton, cotton-poly blend, cotton fleece, tri-blend, ringspun cotton
- Color capability
- Full-color CMYK plus white underbase, opaque on darks
- Wash durability
- 60-plus washes at standard care, tested on Bella+Canvas 3001
- Stretch tolerance
- Moderate; distorts if garment is stretched more than 10% during peel
- Best applications
- Ready-to-press production, gang sheet runs, streetwear, restaurant staff shirts
- Worst applications
- Athletic stretch panels, silicone-coated fabric, waterproof shells
Cost & workflow
- Cost per unit at volume
- Included in transfer price; no separate media SKU on ready-to-press orders
- Line speed
- Roughly 20 to 30 percent faster than cold-peel on a two-press station
- Common failure mode
- Cold press = film sticks. Overheated press = ink yellows. Rushed peel = ghost image on film.
What this is designed to run next to.
Every pairing below is one we set on the press ourselves. If a substrate or transfer type is not here, it is either wrong for this material or we have not proven it enough to publish.

Where this is the wrong tool, and what to reach for instead.
You are pressing onto a 4-way stretch athletic panel.
Hot-peel wants to be pulled while the fabric is still expanded from the press platen. On stretch panels the fabric recovers under your hand mid-peel and the design distorts. Use cold-peel so the ink is fully bonded before the fabric moves.
Use Cold-Peel Film insteadYou want a glossy, plasticky finish.
Hot-peel finishes matte with a fabric-like feel. If your art is a photorealistic image on a black tee and you want the ink to look wet, cold-peel gives you that finish and hot-peel does not.
Use Cold-Peel Film insteadYou have no consistent press temperature.
Hot-peel has a 15-degree working window. If your operators are running one press at 280 F and another at 330 F because the heat platen is out of calibration, half your peels will fail. Fix the press first, then order hot-peel.
The failures we watch shops repeat every week.
Peeling at 30 seconds instead of 5.
Hot-peel is a hot-peel window, not a hot-peel wait. Once the film cools below about 180 F the release coating relocks. If you get pulled off the press by a phone call, walk it back to the press, hit it for 3 seconds, and peel immediately.
Peeling straight up instead of at an angle.
Straight-up peel loads the ink layer in tension. Ink chunks come off with the film. Angle the pull toward yourself at about 30 degrees; the peel front does the release work, not the whole sheet at once.
Storing rolls next to a heater or in a truck.
The release coating cures at heat. If a roll gets to 130 F in the back of a delivery van in July, the coating pre-triggers and the film will refuse to release cleanly at press time. Store climate-controlled, sealed until use.
Reusing carrier for a second press.
Hot-peel carrier is one-and-done. The release coating is consumed in the first peel. Re-pressing with a spent carrier scorches the shirt and does not re-transfer ink.
Materials this is often confused with.
Cold-Peel Film
Peel after full cool. Glossy finish, better on stretch, slower on a production line.
PET Carrier Film
The polymer substrate underneath both hot-peel and cold-peel. The parent material.
White Ink Underbase
The layer between hot-peel carrier and CMYK color that makes the design opaque on dark shirts.
Order transfers pressed on the film we actually stand behind.
Every ready-to-press transfer Golden DTF ships defaults to hot-peel. No upcharge, no supplier lottery, no film we have not run through 60 wash cycles ourselves.
