Two finishing techniques dominate premium packaging: hot foil stamping and spot UV. They are often confused because both add a reflective element to a box. The differences matter — in cost, in feel and in how the design is read at retail. Zhengyang Packaging applies both finishes at its Dongguan factory, which holds ISO 9001 and FSC CoC certification.
Hot foil stamping
A heated die presses a thin metallic film onto the board under high pressure.
- Look — true metallic surface (gold, silver, copper or holographic film).
- Feel — raised, stamped impression; strong sensory appeal.
- Best for — logos, brand names and small design elements that must dominate the design.
- Considerations — per-piece cost is higher; large solid foil areas cost more and can be harder to control.
Spot UV coating
A clear gloss varnish is applied only to selected areas (your logo, a pattern), leaving the rest of the surface matte.
- Look — glossy gloss against matte background; depth comes from contrast, not metal.
- Feel — smooth, slightly raised varnish; no embossed impression.
- Best for — geometric patterns, typography and “soft touch” premium designs.
- Considerations — lower cost than foil; less striking in small logo sizes; requires accurate registration.

The technical detail most buyers miss
Both processes are incompatible with some papers and finishes, so decisions must be made together with the paper stock. A matte lamination + spot UV combination, for example, gives the classic “deep black, glossy logo” look used across luxury cosmetics.
Share your artwork with your supplier early — the finish should be specified in the same design file as the die line, not added at the end.
