Sollex Titanium Nitride (TiN) Coated Blades
Titanium Nitride coated blades improve wear resistance and blade life in industrial cutting, but the right coating depends on the material and cutting process.
What is Titanium Nitride (TiN) coating on industrial blades? Titanium Nitride (TiN) is a thin, gold-colored ceramic coating applied to the cutting edge of industrial razor blades and knives using advanced PVD technology. It increases hardness, reduces friction, resists adhesive buildup, and extends blade life up to four times compared to uncoated steel. Sollex TiN-coated blades deliver cleaner cuts, lower downtime, and are fully food-safe for packaging and film converting applications.
Based on more than 40 years of industrial slitting experience, Sollex has found TiN coatings to be highly effective in abrasive converting applications where long blade lifetime, edge retention and reduced blade changes are key priorities. However, in applications where friction, heat generation or material build-up is the main challenge, lower-friction coatings may deliver better cutting performance.

Which Sollex blade types are available with TiN coating?
Have you ever noticed the distinctive golden shine on some converting industrial blades or their cutting edges that seem to keep cutting material shift after shift? That yellow color comes from titanium nitride TiN ( also known as tinite ), a special wear-resistant ceramic coating on the blade edge that extends the life of industrial tools. Sollex applies the TiN coating to its slitting knives, slotted razor blades, three-hole blades, injector blades, and custom-made machine knives, giving converters and packaging companies an easy way to reduce downtime while keeping cuts ultra-clean and food-safe.
All Sollex titanium-coated industrial knives and blades have “T” or “-T” in the article number.

What are the performance benefits of TiN-coated blades?
Sollex blades with Titanium Nitride coating on the cutting blade edges enhances the blade’s resistance to both adhesive and abrasive wear, making it ideal for cutting demanding materials such as plastic films, laminates, foils, and adhesives.
TiN coatings are commonly recognized by their characteristic gold-yellow surface color. The gold appearance mainly serves as a visual identifier and can also help indicate coating wear. TiN has a microhardness of approximately 2300 HV and a coefficient of friction of around 0.4 against dry steel.TiN coatings are commonly recognized by their characteristic gold-yellow surface color.

Feature | Uncoated Steel Grade Blade | Sollex TiN-Coated Blade |
|---|---|---|
Wear resistance | Moderate | Excellent, coating protects edge |
Friction level | Higher, risk of material buildup | Lower, reduces sticking |
Blade life | Standard | Up to 4x longer |
Cutting precision | Degrades over time | Maintained over longer production runs |
Corrosion protection | None (carbon steel) or minimal (stainless steel) | High, coating forms a protective layer on the cutting edges |
Edge strength | More prone to chipping | Higher resistance to edge deformation |
Temperature resistance | Limited | Stable performance up to 600 °C |
Compatibility with food contact | Varies | Yes, food-safe coating |
Limitations of TiN Blade Coatings
Although TiN is a proven and reliable coating for many industrial slitting and converting applications, it is not always the optimal choice where low friction is critical. Compared with specialized low-friction coatings, TiN has a higher coefficient of friction, which can create more cutting resistance in certain materials.
Based on Sollex’s experience, TiN may be less suitable for highly sticky, sensitive or additive-rich materials, as well as paper and cardboard. Films containing limestone, calcium or similar mineral additives can create build-up on the blade edge and blade sides, reducing slit quality, edge stability and production consistency over time. For these applications, Sollex recommends Ceramic (K) coating. as a more suitable alternative to improve process stability and reduce material build-up.
For similar reasons, TiN coatings are not always optimized for thin stretched film at high speeds, PCR/PIR film or printed film, especially when final product quality is sensitive to friction, dust, heat or edge defects. In these applications, Sollex recommends Zero-Friction (Z) coating. to reduce friction, minimize material build-up and support cleaner, more stable cutting performance.
Where are TiN-coated blades used in industrial cutting?
The use of Sollex TiN-coated blades leads to more stable production processes, cleaner cuts, and lower tooling costs over time. Whether in packaging, plastics, or industrial converting, the coating ensures blades stay sharper and more reliable.
Industry | Use Case Example | Why TiN Coating Matters |
Plastic film converting | Slitting polyethylene, polypropylene, barrier films | Reduces friction and extends blade life |
Food processing & wrapping | Film and foil slitting, often in contact with food | Food-safe, clean edges, no contamination risk |
Laminates & multilayer films | Cutting through composite plastic structures | Coating protects edge against abrasive wear |
Nonwoven & textile processing | Cutting dense or layered synthetic materials | Increases edge durability, resists snagging |
Sollex TiN-coated blades are engineered for industrial environments where standard blades wear out too quickly or struggle with heat, adhesives, or buildup. These coated blades deliver the best results when cutting difficult materials or operating under continuous production conditions.
Which materials are best cut with TiN-coated blades?
Material Type | Example Products | Blade Type Commonly Used |
|---|---|---|
Plastic films | PE, PP, PET, PVC*, PIR*, multilayer films and thin stretched films* | Slotted or three-hole blades |
Foils and laminates | Aluminum, paper*/foil composites | Slotted blades, injector blades |
Adhesive-backed substrates | Labelstock, protective films | Three-hole blades |
Flexible packaging materials | Food wraps, sachets, multilayer film and thin stretched films* | Machine knives |
Nonwoven or fibrous materials | Technical textiles, hygiene products | Injector blades, machine knives |
Construction materials | Roofing felt, linoleum, carpet, reinforced rubber, vinyl, adhesive material | Utility blades |
*For additive-rich films, PCR/PIR materials, printed film, paper-based materials or thin stretched film at high speed, Sollex recommends evaluating the full cutting process before selecting TiN. In these applications, blade geometry, coating friction, machine speed and final edge quality can be more important than wear resistance alone.
These blades are especially effective in continuous and automated production, where reduced blade changes and minimal machine stoppages translate directly into improved efficiency and profitability.
