In daily life, we often see many products with some designs or designs. It is because of their existence that our products are more beautiful in appearance design and more attractive to consumers. Then there will be a friend who is more curious. How does this pattern or pattern be processed? How is he printed on the product? In fact, this is a process called thermal transfer printing film . I will bring everyone together to learn about the relevant knowledge of the thermal transfer film and hope to help you.

Application of thermal transfer film
The scope of application
Printed thermal transfer printing film engraving plate engraving, mainly used for transitional color, rich sense of graphics and text, can reproduce the characters, landscapes and high-grade graphic effects, print graphics, clear, accurate, strong adhesion, etc. In bulk, demanding plastic products, cultural and educational supplies, daily chemical packaging and so on. Thermal transfer film hot stamping temperature of 120 degrees Celsius -240 degrees Celsius. Applicable to abs, as, ps, pvc, pmma, pp, pe and other plastic products, metal, wood and other coating surfaces.

Production of thermal transfer film
Before the thermal transfer film is printed and printed, careful analysis and research are first performed according to the requirements of the customer, and then the printing process step is performed.
1. Preparation of substrate film
There are many kinds of carriers for thermal transfer film, and the most widely used is PET, which has the characteristics of good dimensional stability, uniform tension, good heat resistance, and good release properties. In particular, there is a clear advantage in the reproduction of color-graded manuscripts. Film specifications such as width, thickness, and grade are selected according to the manufacturer's requirements. At the same time to check the flatness of the film, whether the tube material has "robber", "flipped" and other conditions that do not meet the quality requirements.
2. Preparation of release agent
Release agent is a low viscosity transparent resin with release, film formation and adhesion, because the solvent evaporation rate in the release agent is faster, so in the coating process, pay attention to control the viscosity, that is, control The solid content of the release agent, the solid content is generally controlled at about 23%, if the solid content is less than 19%, the heat transfer film after transfer coating agent transfer effect is not satisfactory. At the same time pay attention to the transparency of the release agent, otherwise it will affect the effect of the printing layer.
3. Preparation of ink
Thermal transfer ink belongs to the gravure ink. The drying of the ink mainly depends on the volatilization of the solvent. After the substrate film is determined, the appropriate ink is selected according to the purpose of the printed matter and the nature of the printed material or according to the requirements of the construction sheet. Check the ink fineness, viscosity, hue, tinting strength and other indicators to see if all meet the printing quality of the ink requirements.
4. Preparation of adhesives
The adhesive for thermal transfer is hot-melt adhesive, which is a colorless transparent or light yellow viscous liquid. After coating and drying to form a film, the film quality is transparent, and it has excellent compoundness on the surface of coated release agent and ink. Degree and excellent flexibility, abrasion resistance, resistance to water and acid and alkali and other media ability, good weather resistance.
Thermal transfer film hot stamping processing considerations
Hot stamping is a special printing process. Its working principle is very simple. The graphic on the film is transferred to the product through heating and pressing. However, in the specific production practice, the quality of the product must be improved and production must be improved. Efficiency, also need to pay attention to the following points:
Note one: keep clean
1 It is necessary to keep the worktable, guide rollers, buttons and other components of the machine clean and free from dirt such as oil stains;
2 to maintain the film clean, can not be contaminated with oil, fingerprints, dust, etc.;
3 to keep the plastic head clean, there can be no dirt, coke sticking on it;
4 The operator's hands should be kept clean and there should be no sweat or oil stains on the flower film or on the hot products;
5 To keep the objects to be heated clean, do not get dust, oil, etc.;
Note two
Thermal transfer film hot stamping temperature, hot stamping temperature according to the hot stamping equipment, hot stamping film, hot stamping different and different, not blind pursuit of hot stamping temperature higher (or lower the better), should be hot stamping The effect is a benchmark to determine the stamping temperature.
Note three
Heat transfer printing film stamping pressure, hot stamping pressure must be adjusted to the most appropriate, or too large to easily hurt the rubber head and the object was too small, but also affect the hot stamping effect. After adjustment to the optimal stamping pressure, the pressure adjustment should be locked in order to avoid changes in mass production.
Note four
Thermal transfer printing film hot stamping time (speed), hot stamping time (speed) should be determined according to the specific stamping material, in the case of guaranteeing the hot stamping effect, the faster the faster the production efficiency, but some products due to some special Conditions must be limited to slow hot stamping.
Editor's summary: The above is mainly for everyone to introduce the method of thermal transfer film processing and we need to pay attention to in the implementation of this matter, I hope you must read in detail, and then ensure that your operation can be successful, or to improve their own Success rate of operation.
