It is especially useful for teams that require reliable cutting, slitting, and converting solutions for precision-critical healthcare and medical packaging applications.
Syntegon-Compatible Zigzag Cutting Blade for Stick Pack & Sachet Packaging

In high-speed stick pack and sachet packaging, the cutting blade is not just a spare part. It is a performance-critical component that affects uptime, cut quality, easy-tear performance, packaging consistency, and cost per produced unit.
For one leading pharma manufacturer, the existing cutting setup met the baseline requirement — but it did not deliver the level of blade lifetime, cut consistency, and production stability needed in a demanding, high-volume environment.
The customer needed a better solution.
That challenge became the starting point for the development of the P1161: a Syntegon-compatible zigzag cutting blade engineered to improve performance in stick pack, sachet, and portion pack production for Syntegon VFFS machines.
The result was a custom-developed blade that delivered better cutting performance than the original standard blade solution, with longer service life, improved precision, and more stable production.
The Challenge: High-Speed Packaging With Tight Cutting Requirements
In pharma packaging, every detail matters. Cut quality, repeatability, opening performance, and production stability all have a direct impact on operational efficiency and end-user experience.
The customer’s production line required:
- High cutting precision at production speed
- Reliable easy-tear functionality
- Aluminum laminates
- Higher output and uptime
- Consistent zigzag cuts
- Long blade lifetime
- Reduced blade changes
- Stable performance across demanding packaging materials
The existing OEM knives fulfilled the basic cutting function, but the customer needed more than a standard replacement part. They needed a cutting solution that could reduce wear, improve consistency, and lower the total cost per cut.
This is a common challenge in stick pack and sachet packaging. Materials such as aluminum laminates, plastic laminates, paper-based laminates, and recyclable mono-materials can place significant stress on the blade edge. Over time, this leads to wear, inconsistent cuts, reduced easy-tear performance, and more frequent downtime.
In this case, the cutting blade had become both a technical and financial bottleneck.
Many packaging manufacturers face similar challenges:
- High cost per cut due to frequent blade replacements
- Difficult materials such as aluminum laminates causing rapid wear
- Inconsistent zigzag cuts affecting packaging quality
- Downtime impacting overall equipment efficiency (OEE)
- Unclear ROI from existing blade solutions
Why the Standard Blade Was Not Enough
Standard OEM blades are often designed to meet broad machine requirements. They are suitable for many applications, but they are not always optimized for the specific material, production speed, cutting geometry, or performance targets of an individual line.
For this leading pharma manufacturer, the standard blade solution was not delivering the desired balance between durability, precision, and production economy.
The key issues included:
- Blade wear during high-volume production
- Reduced cutting consistency over time
- Frequent blade changes
- Variation in easy-tear performance
- Increased downtime and maintenance effort
- Higher cost per produced unit
The customer did not need a new machine. They needed a better-performing critical wear part.
That is where Sollex developed a custom-engineered alternative.
The Solution: A Custom-Engineered Syntegon-Compatible Zigzag Blade
The P1161 was originally developed together with a leading pharma manufacturer to solve real production challenges in a demanding stick pack and sachet packaging environment.
Instead of treating the blade as a standard consumable, Sollex approached it as a precision component. The application was analyzed in detail, including cutting requirements, packaging material, blade geometry, edge design, tolerances, wear behavior, and production conditions.
The result was a serrated industrial knife designed specifically for zigzag cutting in relevant Syntegon packaging lines.
The P1161 is compatible with Syntegon zigzag cutting applications, including use in relevant Syntegon VFFS machines and packaging lines where stick packs, sachets, and portion packs are produced at high speed.
It can replace existing blades, including reference 56941693, allowing manufacturers to upgrade cutting performance without major machine modifications.
Built for Performance: Material, Geometry, and Precision
The performance of the P1161 comes from the combination of blade material, edge geometry, and application-specific design.
The blade is manufactured from D2 tool steel, selected for its high wear resistance, long edge retention, and ability to handle demanding packaging materials such as aluminum laminates.
It features a finely toothed, one-sided ground zigzag edge designed to support:
- Clean and precise cuts at high speed
- Consistent easy-tear functionality
- Reduced variation in packaging quality
- Stable performance over longer production runs
- Improved blade lifetime compared with standard blade solutions
The blade is delivered without coating, allowing the cutting geometry and steel properties to perform without compromise.
This makes the P1161 especially suitable for applications where precision, wear resistance, and repeatable cutting performance are more important than simply replacing the existing blade like-for-like.
Designed for Demanding Packaging Materials
Modern stick pack and sachet packaging often involves complex, high-resistance materials. These materials can accelerate blade wear and make consistent cutting more difficult.
The P1161 is optimized for demanding materials such as:
- Aluminum laminates, including PET/ALU/PE
- Plastic laminates, including PET/PE and BOPP/PE
- Paper-based laminates
- Recyclable mono-materials such as PE and PP
- Nonwoven materials
- Functional foils and specialty materials
This makes it suitable for both traditional pharma packaging and newer material structures developed for more sustainable packaging formats.
Proven Improvement Over the Original Blade Solution
The P1161 was developed to outperform the original standard blade solution in the customer’s production environment.
By adapting the blade design to the application, Sollex was able to improve the cutting process across several critical areas:
- Longer blade lifetime
- More consistent zigzag cuts
- Improved easy-tear performance
- Fewer blade changes
- Reduced downtime
- Lower cost per cut
- More stable production quality
Where the original blade met the basic requirement, the P1161 was engineered to deliver a higher level of performance.
For manufacturers running high-volume stick pack or sachet production, these improvements can have a direct impact on overall equipment efficiency, maintenance cost, packaging quality, and production economy.
A Practical Upgrade for Existing Syntegon Lines

One of the key advantages of the P1161 is that it offers a practical upgrade path for existing Syntegon packaging lines.
