Blades for Kampf Slitter Rewinder Machines
Slitting and rewinding machinery is used for the processing and converting of flexible materials and plastic film rolls. The slitter rewinders convert the material for further handling, whether for packaging, printing, or lamination. Kampf and its newly unified partner, Atlas Converting, lead this market by offering a wide range of slitter rewinder machines for flexible material manufacturers and web converters. Their industrial slitting equipment support a wide variety of materials, including LDPE, HDPE, BOPP, BOPET, BOPA, CPP, and laminated materials, positioning Kampf as a leading supplier of plastic film slitting machines and a cornerstone in flexible material processing.
What Is a Slitter Rewinder Machine?
A slitter rewinder is a machine that cuts a big roll of material into smaller rolls. The first step is to unroll the wide roll, which is called the master roll. Then, the material is carefully cut into several narrower strips. During this step, the edges are often cut to get rid of any bumps or extra material, which gives the finish a clean and precise look. After being cut and slit, each strip is then rolled back up into its own roll. This method is often used to work with materials like plastic film, paper, foil, textiles, and laminated composites. The slitter rewinder makes sure that the material is ready for the next step in manufacturing or converting by making the edges thinner and better.

Slitting Techniques
Razor blade slitting is preferred for thin films like BOPP and BOPET due to its clean cut and minimal dust generation. Burst cutting, on the other hand, is employed when slightly thicker or more rigid films require a controlled split. Shear cutting excels in applications where laminated or multi-layered films demand strength and accuracy. Among these methods, razor slitting stands out for its simplicity and efficiency when used correctly. The precision of the slitting razor blade plays a critical role in achieving clean, consistent cuts and minimizing production waste.
Sollex Razor Blades: Recommendations for Kampf Slitting Machines
Companies that produce plastic films, flexible packaging, or laminated materials and use Kampf or Atlas slitter rewinder machines can improve their cutting quality by using Sollex slitter razor blades.
Sollex offers plastic film producers and converters, flexible packaging manufacturers, label and adhesive tape producers, lamination and coating companies, paper and foil converting companies, extrusion film manufacturers, and recycling and reprocessing plants (handling films and laminates) proven blade coatings and designs tailored for high-speed, razor-based slitting systems. Slotted razor blades such as models 5Z, 5K, and 5T are particularly suitable for film processing applications. The 5Z features a zero-friction coating and performs exceptionally well on materials like polyethylene, BOPE, PET, and PCR films. The 5K blade includes a ceramic coating that resists wear from abrasive fillers, while the titanium-coated 5T is ideal for PE and PET films, providing excellent durability.
Sollex 3-hole razor blades, including models like 2-020-Z and 2-030-Z with zero-friction coating or 2-020-K and 2-030-K with ceramic coating, are designed for precision slitting with minimal waste. These blades are thinner and highly accurate, making them suitable for printed, metallized, or laminated films. For applications involving recycled plastics or bio-derived films, thinner blades such as 2-013-K or 2-013-Z ensure razor-sharp results with reduced web deformation.
Material to cut | Blade recommendation | Key benefits |
|---|---|---|
Thin BOPP, BOPET, CPP, BOPE | Clean cuts, low dust, high throughput | |
Films with abrasive additives | 5K (slotted, ceramic coated) | Wear resistance, sharpness retention |
PE, PET, polymer films | 5T (slotted, TiN coated) | Extreme durability in long runs |
High precision, minimal waste production | 2-020-Z / 2-030-Z (3-hole zero friction) | Thinner profile, clean slit, efficiency |
Abrasive or additive-heavy films | 2-020-K / 2-030-K (3-hole ceramic) | Wear durability, razor-like cut quality |
Films with fillers or recycled content | 2-013-K / 2-013-Z | Thin-edge razor precision, reduced scrap |
In Kampf machines like the PrimeSlitter BlackLine, ProSlitter BlackLine, and TitanSlitter ER610, where razor slitting in air or groove is commonly applied, Sollex slotted and 3-hole razor blades deliver superior cut quality, fewer stoppages, and longer tool life.
By integrating Sollex razor blades, converters not only improve slitting efficiency but also achieve greater control over edge trim, tension, and product quality in flexible film conversion.
