Spot UV or foil stamping on flexible packaging bags?

Want to make your packaging stand out on the shelf but not sure how?

Spot UV¹ and foil stamping² are two popular finishes that can enhance the look, texture, and impact of your flexible packaging bags³.

I used to think packaging was just about function. Then I learned how finishes like Spot UV¹ and foil could completely change how customers see your brand.

What is the difference between spot UV and foil stamping²?

They both shine, but not in the same way.

Spot UV¹ adds clear gloss to specific areas of the bag, while foil stamping² uses metallic foil⁴ pressed with heat for a reflective, premium look.

Dive Deeper: Technique, texture, and use cases

Application methods

• Spot UV¹ uses a liquid varnish applied to targeted areas, then cured under ultraviolet light. It creates raised, shiny highlights.
• Foil stamping applies colored or metallic foil⁴ using heat and pressure. It’s ideal for metallic logos, borders, or patterns.

Visual impact

Cost and production

• Spot UV¹ doesn’t require a die, so it’s more affordable for short runs.
• Foil stamping needs a custom metal plate, increasing cost but adding prestige.
