If you’ve ever bought a candle with a beautiful label, only to see it curl, fade, or peel after a few burns, you know how frustrating it can be. For candle brands, the label isn’t just decoration it’s part of the experience. A premium label should stay flawless no matter how many times the candle is lit. That’s where heat-resistant metal labels come in.

In this guide, we’ll explore what makes metal candle jar labels so effective, the materials and adhesives that work best, and how to test them for durability. Whether you run a boutique candle brand or produce candles in bulk, here’s everything you need to know.
Why Plastic Candle Labels Fail
Candle jars are exposed to:
- Heat: Rising temperatures from the flame warm up the container.
- Wax residue: Oils and wax can weaken adhesives.
- Moisture: Condensation in certain environments may cause peeling.
Paper or plastic stickers often can’t handle these conditions. They warp, discolor, or detach making even a premium candle look cheap.
Why Heat-Resistant Labels Are Essential
Using custom metal labels solves these problems. Here’s why:
- Durability: Metal doesn’t warp under heat like paper.
- Premium perception: Shiny, embossed, or brushed finishes make candles look more luxurious.
- Brand protection: Your logo stays visible and intact from the first burn to the last.
- Social media value: A flawless label keeps your product Instagram-worthy even after months of use.
Best Materials for Metal Candle Labels
Not all metals behave the same way around heat. Here are the top options:
✅ Aluminum
- Lightweight and corrosion-resistant
- Can be brushed, polished, or anodized for color
- Affordable, making it popular for candles in the mid-premium range
✅ Brass
- Warm, golden look that fits artisanal or luxury brands
- Sturdy and heat-resistant
- Works well with embossing for a vintage aesthetic
✅ Copper
- Distinct reddish tone that develops patina over time
- Perfect for rustic or boutique candle collections
- Heavier than aluminum but very durable

Adhesives That Withstand Heat
The adhesive layer is just as important as the metal itself. For candle jars:
- High-temperature adhesives ensure labels stay attached even as glass heats up.
- Permanent acrylic adhesives perform well on glass and metal surfaces.
- Pressure-sensitive adhesives provide a strong bond without extra tools.
At Schild Inc., we recommend adhesives tested up to 120°C (248°F) for jar and tin applications.
Testing Steps for Heat-Resistant Labels
Before rolling out a full production run, it’s smart to test your metal candle jar labels under real conditions:
- Burn Test: Place the label on a jar and burn the candle for several hours. Check for discoloration or adhesive failure.
- Temperature Simulation: Expose the jar to cycles of heat and cooling to mimic real usage.
- Wax Contact: Let wax residue touch the label edge to ensure adhesive strength.
- Moisture Resistance: Store candles in humid conditions to test adhesion.
Only labels that pass all four steps should move into production.
