Heat Transfer PET Film For DTF Printing | Teng Yang Factory-Direct
Heat transfer PET film designed for DTF (direct-to-film) printing moves your design from the print bed to your finished T-shirt, cap, or bag in a single hot-peel or cold-peel step. This transfer film is a textile-printing substrate, meant for print shops and distributors, not for a decorative surfacing film. Teng Yang provides it factory-direct, either in bulk rolls or custom-cut sheets, available with both hot-peel and cold-peel modes, as well as OEM sizes for private-labeling.

Why This Matters in Practice
The one aspect screen printing struggles to compete on is cost. For large runs, plates become negligible compared to the per-piece cost, but on short runs of 5 to 200 items, plate setup costs outweigh production savings. While not always cheaper on a per-piece basis than screen printing on massive runs, our film-based workflow is often more cost-effective in that short-run sweet spot.
That completed transfer then gets heat-pressed onto fabric, after which the film is peeled away – either hot or cold, depending on your process line. Because Teng Yang engineers its film in-house, to a common single-side-coated thickness of roughly 75μm, a 20-piece, multi-color order and a 2,000-piece production run use the exact same roll.
DTF vs. DTG vs. Sublimation, Where the Film Comes In
Direct-to-garment (DTG)prints ink directly onto fabric. There’s no film, no intermediate transfer step.
Sublimationis a dye transfer process that requires polyester, and the lighter the fabric color, the better it read.
DTF Process (Our Printer)When our DTF printer prints your design, it lays down a white ink base onto the film before applying the CMYK colors. This enables a single roll to work for both dark and light garments, cotton and poly-blends.
Coating Chemistry Mechanism
The reason a coated PET film absorbs color and white ink together without bleeding comes down to the release/ink-absorbing coating chemistry, not the base PET itself: a coating-composition patent for PET transfer film describes exactly this ink-lock mechanism that keeps print edges sharp on both cotton and cotton-blend fabric.

Hot-Peel vs Cold-Peel, Matte vs Glossy, Spec Comparison
We’re most often asked, “Which is better: hot peel or cold peel?” Honestly, neither is intrinsically superior, that framing is the wrong tradeoff to chase, and picking the wrong one for your line is a real risk to your turnaround time. Which one is “better” depends entirely on your press process, the type of machine you’re using, and the finish you’re looking for.
Hot Peel Process
- When to peel
Immediately after pressing, while still warm
- Production pace
Faster cycle — suited to high-volume batch runs
- Typical finish
Firm bond; some inks read slightly glossier
- Best-fit scenario
Bulk print-shop runs, time-pressured orders
Cold Peel Process
- When to peel
After the transfer cools fully to room temperature
- Production pace
Slower cycle — a cooling step sits inside the line
- Typical finish
Often reads more matte; can feel closer to the fabric hand
- Best-fit scenario
Detail-heavy designs, softer hand-feel priority
On the surface, print shops are divided on whether hot or cold peel provides a more matte finish – some say one, some say the other. This confusion is understandable, because finish is influenced as much by your press parameters (temperature, dwell time) and ink choice as it’s by the film itself. For that reason, we encourage our customers to choose the peel type based on their specific production workflow rather than attempting to find a single “best” choice, and we stock both to ensure you’re never restricted.
If you need to process a large batch of multiple designs within the same day, the fast hot-peel process can be more efficient because it doesn’t require you to wait for the garment to cool on a rack.
If your design has a lot of fine detail or you’re striving for a very soft hand-feel on the finished garment, the slower, more careful separation of the cold peel is a worthy investment of your time.
Many print shops run an “instant” or warm-peel workflow – a short hold, not a complete cool-down – as a compromise between hot-peel speed and cold-peel stability. Teng Yang provides both hot- and cold-peel as standard, so ask about that “middle ground” if your process leans that way.
Engineering Note
Thin-film characteristics – like tensile properties, thickness and heat resistance – are commonly benchmarked against the ASTM D882 test method for plastics below 1mm gauge, as described on Instron’s ASTM standards reference page. Press temperature, dwell time and pressure settings for hot- vs cold-peel are unique to the film and printer model – these ranges listed are industry-typical averages, not a fixed number every DTF PET film shares, so confirm your actual settings during quoting.
Comparing peel modes for your line?“Buyers ask us to just pick a peel mode for them, and honestly we can’t, it depends on what’s running through their press that week. A shop doing same-day rush orders and a shop doing detail-heavy one-offs shouldn’t be buying the same film.”
Ink, Powder & Printer Compatibility
A transfer film is one element of a three-strong kit: the film and ink, combined with the hot-melt powder. Often when people swap supplier for one item in that trio, it brings the same question to mind – will this new roll behave on the printer and powder that I’m already running? The dtf pet film from Teng Yang has been engineered for use with all of the mainstream dtf printer CMYK plus white ink configurations and the most common hot melt powder. In most cases it will integrate smoothly into the line with no need for re-tuning, but in those few cases where the recipe is unusual, we prefer to have that cleared up at the outset rather than have you find out during a production run.
Where Ink Chemistry Enters the Picture
DTF inks are uniquely developed water-based ink formulated to adhere to the film layer and to jet out of the printer to the fabric – the class of inks documented in a water-based DTF ink patent, specifying what it takes for this class of ink to print through the film layer to be permanently held there via powder layer. This dual ink chemistry and film have to work as one team and is why we ascertain the make of your ink and your specific brand of powder when providing you with a quote as not all installations have exactly the same configuration.
Roll & Sheet Formats, Bulk & OEM
This page is intended for buyers who will source their DTF pet film by the roll for a print shop, distribution channel, or private-label brand – it’s not for one roll of fabric for a home printer. Most often new accounts report ordering the wrong roll size for their printer feed, resulting in jams or a wasted stripe of film on every pass; this is especially troublesome once you’re operating at production volume. The range of standard roll widths for this film class runs from about 30cm to 120cm; tell Teng Yang your printer’s actual feed width, and our in-house production team will help you find the perfect fit – not a limiting factor after your roll arrives.
Format: Roll (bulk)
Typical Use Case
Continuous production on roll-fed DTF printers
Who It Fits
Print shops & distributors running daily volume
Format: Sheet (cut-to-size)
Typical Use Case
Small-batch runs, easier storage for lower-volume shops
Who It Fits
Operations piloting a new SKU or a single design run
Format Conversion Note
Converting a bulk cast roll into the width and length you order is a slitting-and-rewinding step, the same category of web-handling equipment covered in a slitter/rewinder machine patent from the printing and graphics industry.
Roll width, length, and thickness can be produced as a custom order – there’s no single catalog size for our materials since a distributor selling under a private-label brand will have different packaging requirements than a print shop with its own brand. Teng Yang offers both; standard sizing for individual users, and custom private-label packaging for distributors. Custom film formulations, such as matte finish, double-sided coating, or specific peel characteristics, are handled the same way as standard orders – just through our standard quotation process.
What to Specify When You Request a Quote
- Your DTF printer’s feed width (roll-fed vs sheet-fed)
- Hot-peel or cold-peel preference, or “either, advise us”
- Roll or sheet format, and estimated monthly volume
- Private-label / OEM packaging needs, if any
If you’re changing suppliers or running your own private label for the first time, it’s smart to be able to test how the film run on your specific printer and powder combination before committing to a large production order. Don’t hesitate to inquire about samples or small trial-quantity options when requesting your quote; we can discuss what best suits your production volume and timeline.
Sourcing for a print shop or distribution business?Manufacturing Capability
Coating drift is that subtle risk in DTF film that buyers almost never think to ask about: A varying release layer that appears fine on the first meter of a roll and starts having peeling problems by the last. Teng Yang engineers against that risk by integrating casting, coating, slitting, and rewinding onto the same core production floor that we use across our broader range of hot melt adhesives, because one floor can maintain coating thickness more reliably than the subbed out mill.
Casting is the base PET substrate, coating is the hot melt that goes on to provide hot peel or cold peel characteristics, and slitting and rewinding take the big roll and put it down to size, holding that coating steady across a run is what keeps a high-quality DTF product consistent from the first meter to the last.
The production equipment for the film line is alongside the existing hot melt equipment, so the same coating and slitting floor that we’ve run for TPU, EVA, and PA film orders runs pet film DTF orders. It’s not subcontracted to a third party mill (which is how a distributor that private labels other companies’ rolls works – they buy it off the shelf and never touch the mill floor). This is where custom width and private label runs really come into play – you go back to the same floor.

This DTF pet film line was an expansion of the film hot melt line, and was set up using the same casting, coating, and slitting floors that run our TPU and EVA film ranges, adapted for a hot/cold peel release layer for garment application. We included a section comparing hot peel vs. cold peel above, because it is, in our experience, the number one question that buyers in a print-shop will ask, but that many supplier spec pages gloss over with a single line spec without any real answer.

FAQ
What is DTF PET film used for?
It’s the transfer medium in direct-to-film printing: your design prints onto the film, hot-melt powder is applied and cured, then the whole transfer is heat-pressed onto fabric and the film is peeled away — leaving the printed image bonded to the garment.
What’s the real difference between hot peel and cold peel DTF film?
Hot peel comes off the garment right after pressing, while it’s still warm, which keeps the line moving faster and is the more common choice for high-volume batch orders where every extra second at the press adds up over a shift. Cold peel needs the transfer to cool to room temperature first, which slows the cycle slightly but gives the adhesive more time to set before it’s disturbed, and some shops find it gives a cleaner edge on fine detail work. Neither is universally “correct” — it’s a production-line decision, not a quality ranking.
Can DTF PET film print on dark fabrics?
Yes — the white ink base layer printed under the design is what makes that possible.
Do you supply DTF film as rolls, sheets, or both?
Both formats, so you can match the film to your printer setup and order volume instead of the other way around.
Can I get custom width, length, or private-label packaging?
Yes — width, length, and thickness are built to order rather than fixed to a single catalog size, and we support private-label packaging for distributors reselling under their own brand.
How should DTF PET film be stored before use?
Keep rolls and sheets in a dry, moderate-temperature space away from direct sunlight and humidity — like most coated polyester films, the release layer’s performance can drift if it absorbs moisture before printing.
Is DTF a good fit for small or mixed-color print orders?
Yes — that’s one of the main reasons print shops adopt it. There’s no plate-making step, so a five-piece order with six colors costs the same setup effort as a five-hundred-piece single-color run, which is exactly the gap screen printing struggles with.
What ink and powder does Teng Yang’s DTF film work with?
The film is compatible with standard DTF ink and hot-melt DTF powder used across the industry’s common printer models. Tell us your printer model and current ink/powder brand when you request a quote, and we’ll confirm compatibility for your specific setup.
How do I pick the best DTF film for my printer and volume?
Start with your printer’s feed width and your typical order volume — roll format suits daily production, sheets suit lower-volume or trial runs. From there, hot-peel vs cold-peel comes down to whether production speed or a softer hand-feel matters more for your typical jobs.
