Different Types of Thermochromic Inks for Label Stickers

As personalization grows in the Label Sticker industry, thermochromic inks are being adopted in multiple ways. These inks can be divided into different categories based on reversibility, temperature range, and pigment composition. Each type offers unique opportunities for custom Label Stickers and specialty Packaging Labels.

1. Reversible vs. Irreversible Thermochromic Inks
Reversible inks can change color back and forth with temperature. They are commonly used in interactive stickers, such as toys or novelty packaging. On the other hand, irreversible inks change color once and never return, making them ideal for security stickers and tamper-proof labels.

2. By Temperature Range

• Low-temperature inks for cold storage labels.

• High-temperature inks for industrial safety labels.

• Body-heat reactive inks for interactive product stickers.

• Multi-step inks for advanced smart labels.

3. By Pigment Composition

• Inorganic inks for durability.

• Organic inks for eco-friendly eco-label stickers.

• Liquid crystal inks for premium luxury packaging labels.

Application Example:
The McDonald’s × Coca-Cola co-branded cups used thermochromic inks to change colors when filled with hot beverages. The design turned ordinary branded labels into an engaging, shareable experience, proving that functional inks can boost brand interaction.

From custom adhesive stickers to branding labels, these ink categories help businesses tailor their packaging to specific needs. With more brands demanding innovative label stickers, thermochromic inks are quickly becoming mainstream.
