What remains unchanged is that when the film is heat pressed on the garment, the film needs to be peeled off to complete the process.
Hot Peel Film
The main release component of hot peel film is wax, the ink absorption performance is relatively poor, and small letters are easy to fall off, but the surface becomes brighter after it is completely cooled. It can save production time, this film is classed as an 'instant peel'.
If it is not peeled off in time within 2/3 seconds, the glue will cold stick to the clothes, causing difficulties in peeling off, and there may be problems such as pattern residue.
Cold Peel Film
The main release component of cold peel film is silicon, the product has good stability, and the colour becomes matte after cooling down.
For this type of film it needs to wait for the DTF film to cool down and then gently peel off (suggest temperature below 55c)
The difference between cold peel and hot peel:
Colour
The colour produced by hot peel film is brighter and the colour performance is better; The colour produced by cold peel film is matte and has a stronger texture.
Colour fastness
The colour fastness of the two is nearly identical.
Pressing requirements
Hot peel film has relatively detailed requirements on pressing time, temperature, pressure, etc. Generally speaking, hot peeling can be easily achieved at 140-160C, pressure high, and pressing for 12 to 15 seconds, with an instant peel.
The cold peel film has similar requirements but with a cold peel.
Tension
Neither of them will stretch or crack after pressing.

Four basic factors for choosing DTF printing film
1. The pattern after transfer has a texture like PU glue, with strong stretch resilience and no deformation.
2. It is suitable for most inks on the market. It can print 100% of the ink volume without any ink accumulation or bleeding.
3. The film's surface remains dry and allows for the application of 50-200 powder without any sticking issues. The image stays intact, and the powder remains separate. Where there is ink, the powder adheres, while areas without ink remain clean and spotless.
4. The release is easy and clean, leaving no ink on the printing film and no layers on the pattern.
