Precision serrated cutting blades specifically designed for the food and flexible packaging industries, suitable for high-speed slitting of various films, composite bags, and sealed packaging. Available in a variety of tooth profiles and materials to ensure clean, easy-tear cuts and compatibility with automated production lines.
Tooth Profile Types | Cutting characteristics: | Typical Applications: | Applicable materials: |
|---|---|---|---|
Single-sided teeth | Wavy cut edges, soft edges, and high safety. | Snack bags, plastic films, flexible packaging | PE, PP, OPP and other flexible films |
Double-sided teeth | Straight and uniform cuts with high cutting precision. | Vacuum packaging, resealable bags, high-end food bags | Composite films, aluminum-plastic films, thick packaging materials |
Dotted teeth | Creates easy-to-tear perforations for easy opening. | Instant noodle bags, seasoning packets, disposable product packaging | Lightweight thin films, coated paper composite materials |
Crossed teeth | Powerful cutting, strong wear resistance, suitable for high-resistance materials. | Multilayer composite films, heavy-duty plastics, high tensile strength packaging | Nylon composites, PET/AL/PE and other high-strength materials |
Material Models: | Hardness (HRC) | Features: | Applicable Scenarios: |
|---|---|---|---|

• Technical Guidance: We provide advice on tooth profile selection, installation and commissioning, and wear detection.
Q: How to choose the right tooth profile?
A: The selection should be based on a comprehensive assessment of the packaging material thickness, tensile strength, tearing requirements, and production line speed. You can provide sample materials, and we will recommend the best tooth profile solution for you.
Q: Do the blades support resharpening?
A: All toothed blades can be resharpened. We provide professional sharpening services, allowing for 3-5 resharpening cycles, significantly reducing operating costs.
Q: Is there food-grade certification?
A: SUS-440C and 420-J2 materials comply with food contact material standards, and material test reports can be provided.
Please provide the following information, and we will match you with the most suitable toothed blade:
1. Packaging material type and thickness
2. Existing equipment model and cutting speed
3. Desired cutting effect (flat/easy-tear/wavy)
4. Monthly usage or annual procurement plan
