By investing in the most advanced European machinery, Yas Kiseh is capable of producing a wide range of PP valve sacks with the highest speed and quality. The CONVERTEX automated conversion line enables us to manufacture AD proTex® sacks with 6-color printing, complete precision, and uniformity.

In our cement sack production lines, we utilize the latest machinery and technologies from Germany's Windmöller & Hölscher (W&H)—a company established in 1869, recognized today as one of the world's leading manufacturers of machinery and systems for the packaging industry.Over 150 years of experience, continuous innovation, and technological advancement have established W&H as a prestigious and influential leader in packaging machinery. Today, its equipment operates in more than 130 countries across over 5,000 global customers.Choosing this technology for our production lines means relying on global expertise and precision German engineering—an infrastructure that enables the manufacturing of sacks with uniform quality, high precision, optimal strength, and superior efficiency.

To achieve the highest quality in cement sack printing, we utilize the advanced SERVOTEX machine—a specialized technology by Germany's Windmöller & Hölscher developed specifically for flexographic printing on woven textiles and industrial sacks.Featuring 6-color simultaneous printing capability, this machine delivers versatile designs, precise details, and consistent colors. Advanced servo-drive systems, precise print process control, and uniform ink transfer ensure stable and professional quality across every production run.On the SERVOTEX SL model, Sleeve technology enables fast and accurate plate changes, significantly reducing setup times between orders. Combined with Revision high-resolution visual inspection and quality control systems, it allows for accurate print monitoring and high-clarity defect detection.The integration of 6-color printing, Sleeve technology, and precision quality control systems enables us to produce sacks with sharp, accurate, uniform, and durable printing—meeting the highest standards of modern packaging.

In the converting and finishing stage of cement sacks, we utilize the advanced CONVERTEX CL-170—one of the most modern generations of cement sack manufacturing machines. Operating at a speed of 170 sacks per minute, it elevates production capacity and efficiency to premium levels. Engineered by Windmöller & Hölscher, it is designed for high-speed operation while preserving uniform sack quality.Its cutting-edge technology ensures fast and stable production alongside precise process control. The integrated nano-perforation system generates highly precise and uniform micro-perforations throughout the sack structure, enhancing performance during the filling process.Additionally, the intelligent defect detection system continuously monitors the production line, identifying flaws and preventing defective products from entering the final stage. The combination of high speed, smart automation, and strict quality control makes CONVERTEX a core component of our production line for achieving high capacity, consistent quality, and manufacturing precision.

Quality is not merely a final inspection step for us; it is continuously monitored throughout the entire sack manufacturing cycle. From raw material intake and preparation to weaving, printing, converting, and final production, every single phase operates under strict supervision by the quality control department.Utilizing advanced measuring equipment and inspection systems, production parameters are continuously evaluated to identify and resolve deviations or defects immediately. This approach minimizes errors and waste while maintaining uniform and dependable quality across all products.Our testing and inspection protocols are aligned with international standards to ensure the final product delivers reliable strength, accurate dimensions, flawless print quality, precision build, and dependable performance.The result of this ongoing vigilance is sacks whose quality is guaranteed not just at the end of the line, but at every single stage of creation.
