Electrochemical aluminum foil hot stamping features

Anodized aluminum is also called hot stamping foil. It is the main material for hot stamping. It is mainly composed of two thin layers, a polyester film substrate and a transfer layer. The basic structure of the sub-layer film, alcohol-soluble dyed resin layer, aluminized layer and adhesive layer.

Electro-aluminum is available in roll foil and leaflet foils. The reel foils are classified into different types according to the materials used to make them. The main products are No. 1, No. 8, No. 12, No. 15, No. 18 and General-purpose, etc. If the color is divided into gold, silver, brown, and light blue, Black, red, green and so on. The performance of various types of electro-aluminum is different, and the suitable forging materials are also different.

For example, No. 1 galvanized aluminum is suitable for hot stamping on paper, leather, lacquered cloth, silk, plexiglass and hard plastic with light color ink, loose texture, and No. 8 galvanized aluminum for hot stamping on paper, varnished cloth and leather; No. 18 galvanized aluminum is suitable for hot stamping on paper products and leather with dark ink and thick lines; and single sheet gold foil is suitable for hot stamping on the covers of lacquer, satin, leather and other materials; gold foil and silver foil are applicable. The cover of the books on cloth, paper, and corrugated paper is stamped; the silver foil is used on the cover of books, vinyl, leather and other materials.

During hot stamping, the hot stamping foil is in contact with the substrate. The transfer layer is fused and transferred to the surface of the substrate by virtue of heat and pressure. After the hot stamping is completed, the polyester film is taken together with the untransferred portion. Peel off.
