Product Description
Choosing the right label material for steel coils, especially hot rolled and cold rolled requires balancing durability, adhesion, and environmental resistance. Here's a breakdown of the best materials based on coil type and application:
Best Label Materials for Steel Coils
Hot Rolled Steel Coils
Hot rolled coils have rough, sometimes oily surfaces and may be exposed to high temperatures and outdoor conditions.
Recommended Materials:
- Polyimide (e.g., Kapton)
- Heat-resistant up to 300C degree celsius
- Excellent chemical and abrasion resistance
- Ideal for coils stored or processed in high-temperature environments
- Polyester (PET) with High-Tack Adhesive
- Strong adhesion to rough surfaces
- Weather-resistant and UV-stable
- Cost-effective for general industrial use
- Aluminum Foil Labels
- Metal-compatible and heat-tolerant
- Can be riveted or welded for permanent ID
- Useful for long-term outdoor storage
Cold Rolled Steel Coils
Cold rolled coils have smoother surfaces and are typically used in cleaner, controlled environments.
Recommended Materials:
- Polyester (PET)
- Smooth adhesion and print clarity
- Compatible with thermal transfer printing
- Ideal for indoor use and automated scanning
- Vinyl Labels
- Flexible and conformable to curved surfaces
- Moisture-resistant
- Good for short-term applications
- Paper Labels (with protective coating)
- Economical for temporary tracking
- Requires clean, dry surface
- Not suitable for harsh environments
