That is to say, the carrier coated with release agent, ink and adhesive is required to be resistant to temperature, pressure and small tensile deformation.
2. Abscission layer
It is a coating of release agent, which keeps solid state at normal temperature, melts at a certain temperature, and reduces the adhesion with the base layer,
It can be separated from the basal layer very quickly without adhesion residue. The release agent is the key to complete the separation of the printing layer from the substrate and the transfer to the substrate surface.
The heat transfer film shall have good wear resistance to protect the color ink, reduce the UV radiation intensity and reduce the invasion of adverse factors on the ink in the air,
It can prolong the service life of ink and buffer the adhesion of substrate film and printing layer.
3. Printing layer
This layer is the basis of aesthetic quality of transfer products. With the development of printing technology and image processing technology, the printing layer has various colors,
Various patterns. In particular, the image and text obtained by intaglio printing can well reflect the delicate image and text, and make the packaging and decoration effect more perfect.
4. Adhesive layer
Its basic performance is to have a high adhesion with the substrate surface to ensure that the printing layer and substrate surface are firmly combined. This layer of adhesive must match the substrate.
Different adhesives, due to the different chemical composition, and substrate adhesion is very different. It should be selected according to different substrate.
