Electronic heat transfer label and preparation method thereof

A method for preparing an electronic heat transfer label, comprising the following steps:

• S1:
• printing an ink on a substrate and drying the ink to form a pattern layer;
• S2:
• printing at least one layer of a first adhesive on the pattern layer and drying the at least one layer of the first adhesive to form a first adhesive layer;
• S3:
• attaching a chip onto the first adhesive layer;
• S4:
• printing at least one layer of a second adhesive onto the first adhesive layer and the chip, and drying the at least one layer of the second adhesive to form a second adhesive layer;
• and
• S5:
• printing at least one layer of glue on the second adhesive layer and drying the at least one layer of the glue to form a hot-melt layer;
• or printing a transparent ink on the second adhesive layer, then spraying hot-melt powder on a surface of the transparent ink, and drying the hot-melt powder and the transparent ink to form a hot-melt layer.
