What is the heat transfer film composed of?

1. Base layer: the carrier of the release layer, printing layer and adhesive layer - thermal transfer base film, thermal transfer base film includes pet film, opp film, pvc film, etc., which need to be selected according to the needs of specific products The corresponding base film, otherwise it will affect the quality of thermal transfer products.

 

 

 

2. Release layer: It is a layer of release agent coating, which maintains a solid state at room temperature, can be melted at a certain temperature, and the adhesive force with the base layer becomes smaller, which can quickly separate from the base film without Stick the remainder.

 

 

 

3. Printing layer: This layer is the foundation of the beauty of the thermal transfer product pattern. The key lies in the selection and matching of the thermal transfer ink. After the thermal transfer process is completed, only the printed layer remains attached to the surface of the thermal transfer product. , so the selection of printing layer materials is particularly important, and a little carelessness will affect the quality of thermal transfer products.

 

 

4.Adhesive layer: its actual composition is a kind of hot melt adhesive. According to different substrates, select the corresponding thermal transfer glue.
