IMPULSE SEALING
The perfect solution for complex heat-sealing applications.
This process entails controlling the sealing temperature for a defined time. A constant heating impulse is generated during each cycle, depending on the rate at which the heat sealing band heats up and cools down. This process ensures a repeatable sealed seam quality and high machine output.
The optimum thermal profile describes a rectangular progression of rapid heating and cooling phases. Our ROPEX impulse technologies, RESISTRON and CIRUS, optimize heating in the best way possible.

RESISTRON - Heat-sealing band technology
RESISTRON is a impulse heat-sealing system for sealing thermoplastics.
The system consist of several application-specific components. The most important ones are the
- RES temperature controller
- RES sealing tool
The tool is a sealing bar with a heat-sealing band and a matching backing pad. For each application, we design the system individually to your requirements and create customer-specific solutions.
Technology Overview:
- Active length almost without restrictions (about 7 m already realized)
- Active width almost without restrictions (about 40 mm already realized)
- 1D, 2D and 3D (Spout, tube etc.) possible
- Useful up to approx. 80 cycles per minute
- Suitable to layer jumps (flexible heat sealing band)
- Cooling of the seam possible
- Cut & Seal-applications with various solutions (cutting wire, beaded band, combination band, silicone profiles for cutting)
- Both sided heat possible (thick films, inserts between film layers, …)
RESISTRON System
- Counterpart with silicone profile
- Opposite heat-sealing tool
- Heat-sealing tool
- Current transformer
- Temperature controller
- Impulse transformer
- Line filter
CIRUS Ceramic heat-sealing solution
CIRUS advantage is the direct load-bearing of the seam, after the sealing process. This is made possible by a cooling unit which results in a significant reduction of the process time and a higher product output.
The special tool design permits new sealing tool characteristics. As the heating line is only a few μm thick, and the resulting heat capacity is also low, extremely high temperature dynamics of 6000 K/s are possible.
Technology overview:
- 1D and 2D possible
- Useful up to approx. 120 cycles per minute
- Partly suitable to layer jumps
- Ultrafast cooling of the seam (due to direct cooling of the heating line) possible.
- Cut & Seal-applications with various solutions (silicone profiles for cutting, cutting device)
- Independence of format (due to direct cooling)
- Easy cleaning (maintenance-friendly)
- Humidity-resistant (FS-tools)
CIRUS System
- Silicone retainer with profile
- UPT heat-sealing tool
- Current transformer
- Impulse transformer
- Line filter
- Cooling unit
- Temperature controller
