Development overview, composition structure, production links and functions of thermal transfer film
1 Development overview of thermal transfer film
Since the 1980s, thermal transfer film has been introduced from abroad to China. It has a wide variety of patterns and can be formulated according to customer requirements. Due to its own quality limitations, after the efforts of many companies, new processes have been continuously improved, processes have been streamlined, and quality has been improved.

Due to its excellent quality and personalized pattern services, it has been recognized by many manufacturers and has been widely used.

2 Composition structure of thermal transfer film
Thermal transfer film is mainly composed of 4 components, generally including base layer, release layer, ink layer, glue layer, etc. Each coating plays its own role and affects each other.

1. Base layer: mainly uses PET film as its base film

2. Release layer: It has detachability and plays a key role in the detachment of the pattern from the base film during transfer.

3. Ink layer: It is made by mixing ink according to the color of the customer's pattern and printing it.

4. Glue layer: It is related to the adhesion of the transfer pattern. If it is used improperly, the pattern may not be printed.

3. The production process of thermal transfer film

The production process of thermal transfer film can be simply divided into these six steps

1. Coating the blank film

2. Cut the blank film according to the corresponding specifications

3. Print the ink and form the pattern the customer wants on the film.

4. Apply glue and dry the flower film

5. Carefully check the quality of the thermal transfer film

6. Carry out the striping process

7. Attach labels, protect the product and pack it

4. The role of thermal transfer film

1. Protect the surface of the product and prevent the product from being scratched.

2. Decorate the product, improve the appearance of the product, and increase the added value of the substrate.

3. The transferred product has clear pictures and texts, is durable and washable, and is not easy to fade and corrode after long-term use.

4. It can cover the product and form an excellent barrier between the pattern and the base color of the substrate, so that the printed pattern can be perfectly reproduced.
