Proven sealing concept designed for reliability, flexibility and less waste.
High-quality sealing is essential for achieving reliable and efficient roll-bag production.
For decades, Roll‑o‑Matic’s Delta Line has built its reputation on a sealing concept that delivers consistency, strength, and efficiency – day after day.
A Sealing Concept Designed for Performance
At the core of the Delta Line is its continuous motion sealing technology. Unlike traditional stop-start systems, this ensures smooth, uninterrupted production – reducing mechanical stress, minimizing maintenance, and maximizing uptime.
With heat applied on both sides of the film, the Delta Line creates strong, uniform seals across a wide range of materials and thicknesses. It also enables double sealing, ensuring high-quality results on thick or multilayer films without compromising speed.
Precision Where It Matters Most
High-quality sealing requires more than heat. It demands control.
The Delta Line ensures full control of the three critical sealing parameters – temperature, pressure, and sealing time – during operation. Adjustable sealing bars follow the film speed throughout the entire sealing process, ensuring sealing takes place in a tension-free zone.
The result is consistently high, uniform sealing quality you can rely on.
Flexible Sealing – Built Around Your Production
The Delta sealing concept is not one-size-fits-all. It is designed to adapt to your exact requirements:
- Multiple sealing widths available: 900 mm, 940 mm, 1100 mm, and 1250 mm
- Delta or Delta Max™ for increased capacity on heavier and multilayer films
- Simplex or Duplex configurations depending on bag length and output needs
- Single or Twin sealing lips for both standard and specialized bag designs
This flexibility allows you to tailor your setup for maximum efficiency – while maintaining consistent, high-quality seals across all applications.
Less Waste. More Efficiency.
The integrated perforation system placed before sealing ensures clean tear-offs and optimized performance.
The perforation knife rotates at a specific angle (similar to scissors). This provides better control compared to traditional perforation systems and very low noise levels. The perforation can be tailor-made to your film type and thickness, allowing easy and clean tear-off.
Perforation settings can be adjusted during operation. The quadrangular knife design offers four usable sides, extending tool life and reducing downtime.
Proven Technology. Continuously Refined.
The Delta Line is a well-established solution, trusted by manufacturers worldwide and continuously upgraded to meet modern production demands. Its sealing concept remains at the core of its performance, delivering reliability, flexibility, and long-term value.
