Key takeaways
              Sealing and cutting are critical for package quality, line efficiency, and output.
Syntegon provides original and customized sealing and cutting solutions for horizontal flow wrappers.
Fin wheels ensure precise film guidance, stable transport, and airtight fin seals.
Sealing jaws deliver consistent temperature, pressure, and dwell time for reliable seals.
Knives enable precise, high-speed cutting with consistent package length and low waste.

            

Sealing and cutting are critical process steps in horizontal flow wrapping. From forming the fin seal to producing precise transverse seals and clean cuts, each component must be carefully matched to the product, film type, and process parameters. Whether you are working with new film structures, changing cycle times, or adapting to new products: We provide customized solutions for both new equipment and upgrades that integrate seamlessly into your production process and help you maintain consistent packaging quality, line availability, and output.

Your customized sealing and cutting solutions for horizontal flow wrappers.

Fin wheels
              Our fin wheels are engineered for precise film guidance and stable sealing performance. They support constant film transport at synchronized speed, minimizing slippage and wrinkles. Uniform sealing parameters ensure strong, airtight seals. Choose what fits your application best: Our stainless-steel fin wheels provide high wear resistance and long-term reliability without the need for additional plating. For enhanced thermal transfer and corrosion protection, Dura-Therm offers smooth and efficient heat conduction – especially for demanding film types.
            

Sealing jaws

Our sealing jaws ensure reliable sealing performance through consistent temperature control, uniform pressure distribution, and precise alignment. They are designed to handle a wide range of film types and deliver stable results even under changing production conditions. A defined and consistent dwell time supports optimal bonding and allows continuous operation without interrupting the production process. Material options include highly durable stainless steel, as well as surface-hardened or coated executions for an extended service life.

Knives

Knives are responsible for the final step in horizontal flow wrapping: the clean separation of individual packages. Positioned after the sealing unit, they precisely cut the film between products in coordination with the sealing jaws. This synchronized movement ensures consistent package length and prevents film fraying. Our knives are designed for continuous, high-speed operation with minimal material waste and reliable cutting performance. Made from hardened steel, they offer high durability and support stable, low-maintenance operation.

Meeting your requirements

As a critical interface between product protection, packaging quality, and machine efficiency, sealing and cutting in horizontal flow wrapping must meet a wide range of technical requirements. At Syntegon, we support you with customized sealing jaws, knives, and fin wheels that match your specific application and integrate seamlessly into both new and existing lines.
