1.What is DTF Transfer Film?

DTF transfer Film is a heat-resistant and non-deformable plastic film. The principle is to use it as a printing technology for flower films on the heat transfer layer. The heat transfer film produced after processing has a release layer coated on the surface to facilitate the transfer of the film to the transfer fabric.

1.Release film
Various types of hot and cold tearing PET release films are provided, which are suitable for different levels of heat transfer products of water-based/oil-based screen printing inks and various special heat transfers, thermal transfer printing substrates, etc.

2.Adhesive
Using water-based polyurethane as the main raw material, the product has good weather resistance, soft feel, high elasticity and water resistance. It is suitable for screen printing production of elastic certification level heat transfer.

3.Adhesive
With polyurethane as the main raw material, it is mainly used in screen printing production processes such as heat transfer elastic level and fine line washing label heat transfer. It has good adhesion to elastic fabric, leather and other materials.

4. Ink
Using high temperature resistant polyurethane elastomer as the main raw material, it has excellent tensile and weather resistance. It is also suitable for heat transfer production of fine patterns and lines. It is resistant to high temperature pressing and does not deform. It belongs to a good level of solvent-based heat transfer ink.

2. What's the Right DTF PET Film Like

1. The texture of the pattern after hot transfer is like PU glue, with strong elasticity and no deformation, and it feels softer than glue (30~50% softer than the pattern printed on the oily coating film). And the feel can be adjusted according to customers' requirements.

2. Adapt to most inks on the market, 100% ink can be printed at will, no ink gathering or ink flow.

3. The surface of the film is dry, and 50-200 mesh powder can be sprinkled without sticking to the powder. The image is the image and the powder is the powder. Where there is ink, it sticks to the powder, and where there is no ink, it is clean.

1.Release is easy and clean, the printed film does not leave ink, and the pattern does not leave a layer. It can distinguish between cold and hot tearing, but it must be stable. The stability here is reflected in the consistency of different batches, so that the color, shaking powder and release are stable.

3. How to know the quality of DTF film?

The quality of the DTF PET film can be judged by the following three aspects:

1. Transparency
The most obvious difference between different quality DTF transfer films is the difference in transparency.
Generally speaking, opaque films produce better results because they tend to have a thicker coating and better ink absorption. Some suppliers will indicate the product name.
DTF films can be divided into 75μ and 100μ, indicating the thickness of the coating film. Typically, 75u DTF film is sufficient for most printing needs, while 100u DTF film is suitable for higher standard printing.

2. Coating Quality
DTF transfer film with poor coating quality looks perfect at first glance. It will repel DTF ink during printing, causing the ink to bleed off the film and stain the printer as well as your hands and clothing.
Another possibility is uneven coating. This will also cause your print to be uneven and you will end up with spots all over your design.

3.High temperature resistance
Last but not least, the base film must be able to withstand high temperatures.
There will be some films that are perfect when printed, but during the thermal transfer process, the base PET film will curl or even melt due to its intolerance to high temperatures. It's very frightening to be faced with this situation at the last minute.

4.What printing film is used in DTF printing?

DTF printing requires the use of DTF film, often called PET transfer film, but not all PET films can be used for DTF printing. Compared to regular PET film, DTF transfer film has a special ink-absorbing coating, so it usually has a matte frosted effect instead of being transparent. Untreated, low-quality films may be cheaper, but they can stain, stick, or damage your clothing.

4.1 How many types of DTF PET films?

1.Cold peel DTF film.
It means that after lamination, the D'TF transfer film must wait for the embossed part to cool down before it can be peeled off.

2.Heat peel DTF film.
The 1ou heat peelable DTF film can be peeled off in seconds without waiting, effectively improving your production efficiency.

3.Smooth DTF film.
Commonly known as single-sided DTF film. There is only a coated DTF film on one side and a smooth PET base film on the other side. Beginners can easily distinguish the printing sides by selecting them.

4.Matt DTF film.
Also known as double-sided DTF film. This does not mean that you can print on both sides. It can only be printed on one side, and the other side is also matte frosted. This is to increase friction during the printing process, making it more stable and preventing the film from slipping and affecting the printing effect.

5.Flash DTF Film.
It adds a glitter powder coating to the coating of the DTF transfer film to achieve the glitter print effect, and can be a perfect substitute for glitter powder.

6.Gold DTF film.
Coated with gold glitter, it gives your DTF more options and a better application range for printing by providing a luxurious shiny gold foil stamping on your design.

7.Reflective colored DTF film.
When you shine a light on this transfer DTF film, you can find a suitable angle to see a color reflection effect similar to the reflective heat transfer film, which is very suitable for personalized customization.

8.Luminous DTF film.
This is a photoluminescent effect that stores light and has a long afterglow. You can use it for special apparel designs and bring more creativity to your customers. It's perfect for T-shirts, bags, shoes, socks, and other materials, and allows our prints to glow in the dark.

9.DTF Gold/Silver Foil.
It has a shimmering metallic sheen that adds sparkle to your designs, and its washability makes the shine last longer.

10. Fluorescent DTF.
The fluorescent effect of DTF is not achieved with transfer film, but requires fluorescent DTF ink. Choose a fluorescent DTF printer to achieve this.

5. Benefits of Using a High Quality DTF Film

A good quality DTF transfer film have the following characteristics:

1.High ink loading, no ink bleeding even when printing at high pass.
2.Fine line printing, the ink does not smear when printed and can print very fine lines.
3.Clean shake powder, no excess DTF polyamide powder adheres to the unprinted area after shake powder, ensuring a smooth edge of the print.
4.Easy to peel off, there is a layer called release layer in the coating of DTF film, a stable and uniform release layer can ensure smooth when peeling off the base film, without adhesion.

High quality DTF PET film has stronger washing fastness, exquisite effect, reliable performance, and will not age for a long time after hot stamping on fabrics.
PET printing film products have high elasticity, anti-stretching, anti-sublimation, anti-slip, no fading, no cracking, no falling off, and washing resistance. High temperature resistance, heat resistance, easy to carve and tear, etc. The transfer film does not require secondary treatment and can be printed directly, which is very popular in the market.
