The T-type Serrated Blade for Packaging Machine is a core sealing and cutting component for various automatic packaging equipment, specially designed for high-speed slitting and heat-sealing of packaging films. Made of high-quality alloy steel, it undergoes precision heat treatment and edge grinding, boasting exceptional hardness and wear resistance. Its unique T-type serrated edge structure ensures simultaneous sealing and cutting, resulting in flat cuts and tight seals, effectively preventing issues like blade sticking and package splitting. Available in a wide range of specifications with customizable options, it is perfectly compatible with pillow-type packaging lines in the food, pharmaceutical, and daily chemical industries.
、 
| Exceptional Sharpness & Longevity |
Manufactured from premium imported tool steel (e.g., SKD-11 or High-Speed Steel M2). Subjected to vacuum heat treatment and deep cryogenic processing, the cutting edge achieves a high hardness of HRC 58-62, offering excellent wear resistance for millions of cuts per sharpening cycle. |
| Rigid T-Type Structure |
| The unique T-shaped profile not only enhances blade strength to prevent deformation when cutting thick films but also optimizes the tooth geometry to reduce cutting resistance, lowering machine energy consumption. |
| Anti-Stick Coating for Clean Cuts |
| Optional PTFE (Teflon) or DLC (Diamond-Like Carbon) coatings are available. These effectively prevent adhesives or molten material from sticking to the blade surface during hot sealing, ensuring smooth, neat cut lines and significantly reducing downtime for cleaning. |
| Precision Ground for Uniform Gapping |
Manufactured using 5-axis CNC grinders in a single pass, tooth tip flatness is controlled within 0.02mm. This ensures consistent clearance with the anvil, eliminating issues like blade gnawing or incomplete cuts. |
Tooth Profile Details: Selection logic for fine, medium, and coarse teeth (Fine teeth for better seal aesthetics, coarse teeth for thick bags).
Cutting Edge Process: Microscope images showcasing the smoothness of our cutting edge compared to standard blades with burrs.
Surface Treatment: Images of Gold Titanium coating and Black DLC coating, comparing their friction coefficients.
Perfect Fit: Extensive database of serrated blade blueprints for mainstream packaging machines (e.g., Tomy, Rovema, and leading Chinese brands). Customization available upon request or sample.
Dynamic Balancing: Every high-speed blade undergoes dynamic balancing before shipment. This guarantees smooth, low-vibration, and low-noise operation at high rotational speeds.
Packaging Solution Advisor: We don't just sell blades. We act as your consultant, recommending the optimal tooth profile and material based on your specific packaging materials (e.g., retort pouches, anti-static bags).
Q: What happens when the blade gets dull?
A: We offer a factory resharpening service. Utilizing our original processes, we restore the blade at only 30% of the cost of a new one, giving your blades a new life cycle.
Q: How do I choose between straight serration and staggered serration?
A: T-Type blades often work with crank mechanisms. For machines with a vertical platen cut, staggered serrations are recommended for a "scissor effect" requiring less force. For rotary continuous motion machines, standard T-Type teeth are typically used.
Q: What is the lead time?
A: Standard models are in stock and ready for immediate dispatch. Custom orders typically ship within 30 working days after drawing confirmation.
