# Thermochromic Sleek Cans for a Hard Seltzer

> A seltzer brand used cold-activated thermochromic ink on 330 ml sleek cans to show when the drink is at serving temperature. Hard seltzer case study.

Canonical: https://www.aluminumcanfactory.com/projects/hard-seltzer-thermochromic-sleek-cans/

**Industry:** Hard seltzer · **Region:** North America

- Format: 330 ml sleek
- Special ink: Thermochromic, activates when chilled
- End: 202 SOT, silver
- Volume: Mixed 40HQ, 3 flavours

## The challenge
The brand wanted an interactive pack that would justify a premium price, without moving to expensive shrink sleeves.

## Our solution
- We printed a thermochromic layer that reveals a pattern when the can is chilled, combined with three flavour colours in a single mixed container.
- Activation temperature and contrast were validated on press samples shipped by air before the full run.

## The outcome
The cold-reveal effect became a central part of the brand’s social media launch and retail display.
