Slitting Blades for Bandera Extrusion Lines
Improve Cutting Quality on Bandera Extrusion Lines with Sollex Razor Blades
In plastic film production, good cutting makes all the difference. Whether you’re producing packaging stretch film, agricultural (agrifilm), lamination, stretch-hood films or working with recycled materials, clean and consistent slits are critical. And if you're running Bandera extrusion and coextrusion lines, you already know how important it is to match top-tier machinery with equally reliable slitting razor blades.
Sollex industrial razor blades are designed to help the plastic film manufacturers and converters get the most out of their extrusion or converting lines.
About Bandera Film Extrusion Lines
Costruzioni Meccaniche Luigi Bandera SpA is based in Italy and has earned a reputation for building advanced blown film and cast film lines. Bandera extrusion lines are used for the manufacturing of single- and multilayer polymer films for packaging, agriculture, medical and food sectors, converting of rolled films and other applications. What makes Bandera Extrusion Intelligence unique is their focus on customization and modular design. They don’t just build machines. They build systems that can evolve as your production needs change. The House of Extrusion, their in-house R&D hub, is also a strong signal of their commitment to innovation, especially in areas like biodegradable film and recycled content.
Cutting & Slitting in Plastic Film Production
Even with high-end extrusion lines, cutting and slitting can be a bottleneck. Common problems include frayed and inferior cutting edges, too much dust, buildup on the blade, rough roll edges, and others. Read more about common cutting problems in our blog “13 common problems when slitting and cutting blown film, and what you can do about them”. These issues slow down production and increase post-industrial plastic waste.
Much of this comes down to blade quality. If the blade isn't optimized for the cutting material, isn't sharp enough, or wears out too quickly, you're left with rough cuts, unnecessary downtime, and much production waste. The solution? Sollex industrial razor blades are engineered for high-speed converting, optimized for modern films, and made to last.
Sollex Razor Blades: Designed for Performance on Extrusion Lines
At Sollex, we manufacture high-performance slitting blades and recycling knives used by the plastic industry across the world. Our slotted slitter blades, injector blades and razor blades with 3 slots are made using high-grade materials and exceptional coatings to ensure long-lasting sharpness and minimal friction when slitting and converting blown or cast films.For Bandera users, that means cleaner slits, less dust, and fewer blade changes.
Blades Recommended for Bandera Extrusion Lines
We’ve worked with many customers running Bandera equipment, and certain Sollex blades keep coming up as top choices:
- 5Z / 5LZ slotted razor blade: a unique zero-friction-coated razor blade perfect for reducing dust and heat in the cut and handles PE, LDPE, LLDPE, HDPE, BOPE,PET, PIR, PCR films well
- 5K slotted razor blade: a reliable, ceramic-coated razor blade for general-purpose film slitting
- 5T slotted razor blade: long-lasting blade with titanium TiN cutting edges for slitting PE and PET polymer films
- 2-020-Z or 2-030-Z 3-hole razor blade: slitting blades with zero-friction coating as thinner alternatives to 5Z blades
- 2-020-K or 2-030-K 3-hole razor blade: converting razor blades with ceramic coating as thinner alternatives to 5K blades that can slit a wide range of films
- 4-60-030-Z long 3-hole razor blade: coated slitting edges with ceramic for extreme durability, ideal for high-speed lines or abrasive films
Each of these models has proven to perform well in Bandera's blown film and cast film systems, especially when the goal is high throughput and consistent edge quality.
Customer Feedback on the Use of Sollex Blades on Bandera Blown Film Line
We recently spoke with a customer in northern Europe running a Bandera 5-layer blown film line. After switching to Sollex zero-friction-coated razor blades, they reported a noticeable difference:
- Blade life increased by about 300 percent
- Slit edges were cleaner, even on thinner multilayer films
- Less dust and debris
Time to Upgrade Your Cutting Process?
If you're using Bandera extrusion or converting lines, it's worth reviewing your current blade setup. The right slitter rewinder blade can give you longer runtimes, better film quality and fewer stoppages. Sollex blades are available in a wide range of sizes and coatings, and we’re always happy to recommend the best option for your specific needs. Whether you’re working with packaging or technical films, multilayer structures, or recycled materials, we have the right blade to match your production.

FAQ
Q: What slitter blades work best on Bandera extrusion lines?
A: High-performance industrial razor blades with ceramic or zero-friction coatings work best on Bandera extrusion lines, as they deliver clean slit edges, low dust levels, and long blade life.
Q: Why is blade quality critical on Bandera blown and cast film lines?
A: Even with advanced extrusion equipment, poor blade quality can cause rough edges, dust buildup, and unstable winding, which reduces film quality and increases waste.
Q: Which Sollex razor blades are recommended for Bandera film production?
A: Commonly used blades include zero-friction slotted blades (5Z / 5LZ), ceramic-coated slotted blades (5K), TiN-coated blades (5T), and coated 3-hole razor blades such as 2-020-Z and 2-030-K.
Q: What materials can Sollex blades handle on Bandera extrusion lines?
A: Sollex blades are suitable for PE, LDPE, LLDPE, HDPE, BOPE, PET, agrifilm, stretch film, lamination film, and recycled PCR and PIR plastic films.
Q: How do zero-friction-coated blades improve slitting performance?
A: Zero-friction coatings reduce drag and heat at the cut edge, resulting in cleaner slits, less dust formation, and improved blade life during high-speed production.
Q: Can Sollex blades reduce downtime on Bandera extrusion lines?
A: Yes. Customers report significantly longer blade life, fewer blade changes, and more stable cutting, which reduces downtime and improves overall productivity.
Q: Are Sollex blades suitable for multilayer and recycled films?
A: Yes. Ceramic and zero-friction-coated Sollex razor blades are specifically designed to handle abrasive additives, multilayer structures, and recycled plastic materials.
Q: How can I choose the right slitter blade for my Bandera line?
A: Blade selection depends on film type, thickness, additives, and line speed. Sollex provides technical guidance and blade testing to identify the optimal solution.
Q: Where can I order slitter blades for Bandera extrusion lines?
A: Sollex supplies industrial razor blades for Bandera extrusion and converting lines. Orders and test requests can be made via order@sollex.se.
