Product overview
The Shaanxi Beiren Environmentally Friendly Rotogravure Printing Machine combines 60+ years of gravure experience with targeted environmental technologies to deliver high-speed, high-precision rotogravure printing while minimizing VOC emissions and energy use. Designed for flexible packaging and label production using water-based and NTNK solvent inks, the machine is validated in thousands of installations worldwide.

Highlights

• Eco-compatible inks: supports water-based and NTNK solvent inks to reduce VOC emissions.
• Energy-saving drying: heat-pump technology with hot-air recycling reduces thermal consumption up to 30%.
• Precision drive: Electronic Line Shaft (ELS) with individual servo-driven cylinders for high register stability.
• High registration: register accuracy ≤ ±0.1 mm.
• Material range: processes mono-material films, biodegradable substrates and ultra-thin films down to 10 µm.

Key functional features
ELS drive eliminates mechanical main shafts, lowering mechanical loss, vibration and maintenance needs. The intelligent drying system couples heat-pump technology with high-velocity drying nozzles and hot-air recycling loops to dry water-based inks effectively while saving energy. Integrated LEL monitoring and designated RTO connection points enable real-time solvent management and thermal treatment of captured emissions.

Material & application capabilities
Supported printing materials:

• OPP, BOPP, CPP
• PE and PET films
• PVC and NY materials
• Biodegradable substrates such as PLA

The machine handles heat-sensitive substrates (e.g., MDO-PE, BOPE) without thermal distortion and supports recyclable mono-PE food packaging, pharmaceutical blister packaging and biodegradable labels with controlled tension and zonal drying.

Quality assurance & testing
Manufacturing and QA include dedicated machining for key components and comprehensive validation for each unit. Typical tests:

• Gas chromatography for residual solvent verification
• Registration accuracy validation under operational conditions
• Energy efficiency audits to confirm real-world savings
• VOC leakage inspections and emission control verification
