Triangular Laminating Machine V-Cut Slitting Blade
Two-hole precision fixed triangular cutter
Double-sided V sharp edge for smooth film slitting
High-efficiency precision lamination machine blade
Film laminator blades are dedicated cutting consumables for automatic film laminating equipment.
We manufacture them from high-hardness, wear-resistant raw materials including high-speed steel and tungsten carbide, which maintains stable sharpness under long continuous production runs.
All blade shapes and dimensions are fully customizable to match different laminator models and lamination processing standards. Our custom blades fit most mainstream laminating machines and help you achieve clean trimming and higher production efficiency.
For film lamination workshops, rough film edges and fast-worn blades always reduce daily output. Conventional flat blades tend to leave jagged burrs on composite film and require frequent downtime for replacement.
Our two-hole symmetrical V-point laminating cutter features double-sided bevel precision grinding. It delivers consistent, burr-free slitting performance on PET, BOPP and multi-layer composite packaging films during non-stop high-speed operation.

Product Application
1, Printing and packaging industry
- Usage: Used for cutting laminating materials for various printing materials such as coated paper and corrugated cardboard.
- Advantages: Sharp blades can cut neatly to ensure that the laminating material is tightly adhered to the surface of the printing material.
2, Advertising industry
- Usage: Cutting laminating materials for advertising posters, flyers, etc. according to the set size and shape requirements.
- Advantages: Sharp blade tips can accurately cut to ensure a smooth and flawless laminating effect for advertising products.
3, Album production field
- Usage: Used for laminating the inner pages of albums to ensure that photos are well adhered to the laminating material.
- Advantages: Smooth and flat blade can prevent bubbles or wrinkles and protect photos from damage due to external factors.
4, Electronic manufacturing industry
- Usage: Used for cutting laminating materials of electronic components such as circuit board protection films and display screen coatings.
- Advantages: High hardness and wear resistance of the blade ensure that no damage is caused to electronic components during cutting.
5, Medical equipment industry
- Usage: Used for cutting laminating materials for packaging of medical instruments and equipment.
- Advantages: Sterile treatment and precise cutting ability of the blade ensure the safety and hygiene of the packaging of medical equipment.
6, Textile and leather processing industry
- Usage: Used for cutting surface protection films of textiles and leather materials.
- Advantages: Sharpness and wear resistance of the blade make the cutting edges smooth to prevent bubbles or wrinkles during laminating.
Core Product Advantages
Low penetration force for easy film cutting
Symmetrical V-point geometry concentrates cutting pressure evenly. It cuts tough composite film, leather and thick paper without extra resistance.
High wear resistance for longer service life
Made of high hardness SKD11 or optional tungsten carbide, it maintains sharpness under continuous friction heat, greatly reducing frequency of blade replacement.
Clean burr-free slitting finish
Precision CNC tapered edge grinding ensures smooth trimming. Laminated film edges stay neat without curling, wire drawing or rough burrs.
Cost-effective OEM replacement part
As high-consumption consumable for laminating machines, it serves as an affordable substitute for expensive original brand blades to cut factory operating costs.
Structural & Craft Features
Two-hole precision mounting structure
Two standard round positioning holes lock the blade tightly on knife holders. No shifting or offset under high-speed reciprocating movement and strong vibration, ensuring precise alignment during installation.
Symmetrical double bevel pointed geometry
Balanced triangular tip with double-sided sharp bevel. Uniform force distribution during slitting prevents deviation of cutting lines.
Tapered progressive cutting edge
Gradual slope grinding from blade back to cutting tip balances sharpness and structural strength, delivering fast cutting performance while resisting chipping.
Strict Pre-delivery Quality Inspection
Each batch of triangular laminating blades undergoes full inspection before packaging and delivery:
Full dimension calibration to match laminator and contour cutter knife seats
One-by-one hardness and sharpness test for double bevel V tip
Surface polishing inspection to eliminate burrs and scratches
Real slitting test on BOPP/PET composite film to verify clean cutting effect
Installation steps
1. Preparation Work
- Shut Down Power: Before installing the blade, make sure the laminator is already turned off and the power supply is disconnected to ensure safety.
- Clean the Blade: Clean any debris or residue left on the new blade and the old blade on the blade holder to prevent affecting the installation and performance of the new blade.
- Check the Blade: Inspect the new blade for any manufacturing defects, such as cracks, chips, or irregular edges.
2. Blade Alignment
- Hole Position: Align the holes on the blade with the holes on the slitter machine blade holder. Ensure that the blade is parallel to the blade holder to ensure cutting straightness.
- Initial Fixation: If the blade is fixed with bolts, first insert the bolts into the blade holes, then align with the holes on the blade holder, gently place the blade down, allowing the bolts to pass through the blade holder.
3. Securing the Blade
- Using Bolts: If using bolts to secure the blade, tighten the bolts evenly with a wrench or screwdriver. Be careful not to over-tighten to avoid damaging the blade or blade holder.
- Using Slots: If the blade is secured through slots, place the blade correctly in the slot to ensure it does not move or shake. - **Magnetic Fixation**: If the blade is fixed magnetically, place the blade on the magnetic blade holder to ensure a strong adhesion.
4. Adjusting the blade:
- Adjusting height: Adjust the height of the blade as needed to ensure proper contact with the laminating material. This is typically done by adjusting the adjustment screws on the blade holder.
- Adjusting angle: If necessary, adjust the angle of the blade to meet specific cutting requirements. This may involve adjusting the position of the blade on the blade holder.
5. Blade testing
- Empty load testing: Run the laminating machine without any laminating material to check if the blade operates smoothly, without any abnormal noise or vibration.
- Loaded testing: Run some laminating materials through the machine to test the cutting effect of the blade. Check if the cutting is smooth, precise, without burrs or uneven edges.
6. Final Inspection
- Check Fastening: Double check all bolts or fastening devices to ensure the blades will not loosen during high-speed operation.
- Clean and Maintain: After installation, clean the blades and blade holder to ensure no residue of fingerprints or oil stains. Regularly inspect the wear of the blades and replace as needed.
