ROPEX is a global leader and pioneer in advanced impulse sealing technology, specializing in the precise joining and cutting of thermoplastics. Since 1976, the company has developed state-of-the-art thermal process solutions that replace traditional continuous heating methods with high-speed, micro-interval electric pulses. This technology allows the heating element to reach exact temperatures within milliseconds and cool down just as rapidly, ensuring repeatable seam quality, reduced material waste, and maximum production efficiency.
Core Technologies
- RESISTRON: Closed-loop temperature control systems utilizing the heating band itself as a sensor for high-frequency adjustments.
- CIRUS: Ultra-dynamic impulse sealing technology designed for high-speed contours, rapid thermal profiles, and cleanroom packaging.
- Self-Sensing System: Controls temperature through real-time mathematical calculations of resistance changes (\(TCR\)), eliminating external sensors.
Main Industry Applications
- Medical & Pharma: Validated, sterile sealing for medical pouches, devices, and infusion bag spouts requiring strict compliance.
- Consumer Packaging: High-speed vertical and horizontal seals for food, refill pouches, stand-up bags, and spouted packaging.
- Battery & Automotive: Heavy-duty, highly precise sealing configurations used specifically for prismatic lithium-ion cells and car seat production.
- Sustainable Packaging: Flawless thermal joint control tailored for bioplastics, recycled PCR/PIR films, and plastic-coated paper packaging.
Technical Services & Support
- Application Consulting: Providing customized parameters (pressure, time, and temperature) and PLC integration support.
- Customized Engineering: CAD design for specialized 3D geometries, closed contours, and simultaneous cut-and-seal systems.
- Material Testing: Real-world feasibility testing including under-water leak detection and tensile strength verification.
