Stamping foil is a transfer film. All the colors and designs are printed on base film such as PET, OPP.
Apply glue on textile, put stamping foil on it, then press them together at 90~100℃.
You’ll see colors and designs on the stamping foil are transfered after taking base film off from the textile.
It is particularly used to make metallic/holographic effect, because you can hardly give the same effect with other products.
More than 400 colors are available.
