Reduce blade wear, improve easy-tear performance, and lower cost per cut with the P1161
In high-speed stick pack and sachet packaging, the zigzag cutting blade is not just a spare part. It is a precision machine knife that directly affects uptime, cut quality, packaging consistency, and cost per unit.
It is a performance-critical 
component that affects uptime, cut quality, packaging consistency, and cost per unit. Many manufacturers struggle with rapid blade wear, inconsistent zigzag cuts, poor easy-tear performance, and frequent downtime—especially when running aluminum laminates, plastic laminates, paper-based laminates, or recyclable mono-materials.
The P1161 was developed to solve these challenges. Originally engineered together with a global pharmaceutical manufacturer, this Syntegon-compatible zigzag blade is designed for demanding stick pack and sachet applications where longer blade life, clean cutting, and stable production are essential.
The blade is suitable for 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.

How the P1161 Improves Performance, Reduces Cost, and Handles Demanding Materials
In high-speed packaging environments, small details have a big impact. Cut quality, uptime, and ease of opening directly influence production efficiency, operational cost, and the end-user experience. For manufacturers working with stick pack and sachet packaging, these demands are even greater. Materials are often complex, speeds are high, and tolerances are tight.
Yet, the cutting solution is often treated as a standard component instead of a performance driver.
This was the starting point for the development of the P1161 zigzag cutting blade. From Standard Blade to High-Performance Zigzag Cutting Solution. The P1161 is a serrated industrial knife engineered specifically for zigzag cutting in stick pack and sachet packaging machines.
Unlike standard blades, it was originally developed as a custom solution for a global pharmaceutical manufacturer, with the goal of solving real production challenges in a demanding, high-volume environment.
The result is a toothed machine knife that delivers consistent performance, longer service life, and improved cutting precision. For manufacturers comparing replacement machine knives for stick pack and sachet packaging machines, the P1161 offers a direct upgrade from standard zigzag cutting blades.
The Challenge: High Cost, Aluminum Materials, and Inconsistent Cutting
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
These issues make the cutting process both a technical and financial bottleneck.
