Hot stamping film is a plastic film that can withstand high temperature without deformation. It can also be used as a membrane switch in the electronics industry. (It will not deform under 100 degrees, and it will stretch a little at 150 degrees.) It is used as a base material for hot stamping, which is convenient to transfer to clothes. PET thermal transfer film can only be used for thermal transfer after processing, and its surface is coated with a separation layer. So what are the ingredients of DTF Film?
What are the components of DTF Film?
Hot stamping film includes 3360 release film, viscose, glue, ink and other chemical materials for printing.
1. Release film: Provide various types of hot and cold tear PET release films, suitable for water/oil screen printing inks and various special hot stamping, heat transfer substrates and other hot stamping products of various levels.
2. Glue: It is made of water-based polyurethane as the main raw material. The product has good weather resistance, soft touch, high elasticity and washability, and is suitable for screen printing production of elastic certified hot stamping.
3. Glue: with polyurethane as the main raw material, it is mainly used in screen printing production processes such as thermal transfer bomb grade, thin line watermark hot stamping, etc. It has excellent bond fastness to elastic fabrics, leather and other materials.
4. Ink: The main raw material is high-temperature-resistant polyurethane elastomer, which has excellent stretchability and weather resistance. At the same time, it is suitable for hot stamping production of fine patterns and lines. It is a solvent-based thermal transfer ink with high temperature resistance and no deformation.
What materials are needed for heat transfer?
Hot stamping is to transfer the flower film pattern to the surface of the carrier through preheating pressure. The hot stamping process is mainly to “print” on the surface of the clothes, and stick a layer of “plaster” on the surface of the clothes.
Heat transfer analysis of substrate
Most of the substrates used for hot stamping are pet sheets. After printing patterns of various colors on the pet sheet, hot melt adhesive should be applied on the back of the patterns. It is this hot melt adhesive that firmly combines the pattern with the clothes, uncovers the waste PET film, and completes the heat transfer process.
Analysis of advantages and disadvantages of hot stamping
Advantages of hot stamping: low cost of plate making, rich patterns and beautiful colors.
Disadvantages of thermal transfer printing: the air permeability is poor after transfer printing on clothes, and the hand feeling is not as soft as sublimation heat transfer printing.
What are the heat press applications?
The hot stamping process has the characteristics of strong color sense, corrosion resistance, acid and alkali resistance, ultraviolet resistance, rain and sun protection, not afraid of water immersion, and air purification. The image is clear, the color is bright, and it does not fade, which is a good product for commemoration and collection.
For example, you can print photos of yourself or your lover on unexpected materials such as ordinary cups, flowers, mice, key chains, etc., give yourself or your lover an unexpected gift, give everyone a surprise, and quickly become popular among college students, white-collar workers, Families, fashionistas!
The core of the DTF Film is the coating technology of the film. It is the key to make a coating on the film that can satisfy the ink printing on the film without melting.
