Hot Foil Stamping
Hot foil stamping is a widely used embossing technique known for its excellent results, broad applicability, and costeffectiveness. It can be combined with debossing/embossing techniques to create 3D foil effects with a relief texture, making it the most common foil stamping process in domestic design applications.
Hot foil stamping is a premium finishing process that transfers metallic, pigmented, or holographic foil onto packaging substrates using heated dies under pressure. It enhances visual appeal, brand perception, and anti-counterfeiting features.
Key Applications in Packaging
Luxury Packaging
Cosmetic boxes, perfume cartons, jewelry cases
Example: Gold foil-stamped logos on premium skincare packaging
Brand Identity Elements
Logos, monograms, typography
Example: Embossed foil brand names on liquor bottles
Security Features
Holographic foils for anti-counterfeiting
Example: Pharmaceutical packaging with tamper-evident foil stamps
Tactile Enhancement
Combined with embossing for 3D effects
Example: Textured foil patterns on high-end chocolate boxes
