Cold foil film is a specialized material used in the cold foil stamping process—a printing technique named in contrast to traditional hot stamping. It utilizes a printed adhesive (ink) to transfer the aluminum layer from the film onto a substrate without heat. This method replicates metallic stamping effects with high efficiency and precision.

Key Advantages: 

High Stamping Accuracy: Capable of reproducing fine lines as thin as 0.06mm without issues like breakage or smudging. 

High Production Efficiency: Operates in-line with offset presses at speeds of 80-120 m/min, eliminating a separate production step. 

Broad Substrate Compatibility: Suitable for various cardboards, plastic films, labels, and heat-sensitive materials. 

Environmental Friendliness: The process requires no heated stamping dies, reducing energy consumption and waste. 

Superior Graphic Effects: Enables simultaneous stamping of lines, dots, text, and solids with smooth gradients and high definition.
