Overview
The Shaanxi Beiren Environmentally Friendly Rotogravure Printing Machine is a web-fed rotogravure press engineered to reduce environmental impact while delivering precise, high-speed gravure printing. It integrates water-based and non-toluene/non-ketone (NTNK) solvent inks, heat-pump assisted drying with hot-air recycling, and an Electronic Line Shaft (ELS) servo drive to lower VOC emissions and thermal energy use. The press supports mono-material and heat-sensitive substrates such as MDO-PE and BOPE for sustainable packaging solutions.

Features

• Electronic Line Shaft (ELS): servo-driven independent control of each gravure cylinder for accurate registration and reduced mechanical losses.
• Low emissions: compatibility with water-based and NTNK inks; design provisions for emission capture and RTO integration delivering significant VOC reduction.
• Energy saving: heat-pump assisted drying combined with hot-air recycling reduces thermal energy consumption.
• Operational efficiency: short changeover cycles, simplified maintenance (no main mechanical shaft oiling) and durable components for continuous production.
• Safety & monitoring: integrated LEL monitoring and emission treatment design points for regulatory compliance.

Advanced Technology
The press pairs ELS servo control with intelligent drying: servo motors independently drive each cylinder to maintain registration under dynamic conditions while a heat-pump system with high-velocity drying nozzles handles slower-evaporating water-based inks and recovers process heat to improve overall energy performance.

Material Versatility

• Supported substrates: OPP, BOPP, CPP, PE, PET, PVC, NY.
• Compatible with biodegradable films such as PLA and with ultra-thin films down to 10 microns through precise tension and pressure control.
• Adapted for mono-material structures (e.g., mono-PE) to support recyclability targets.

Applications

• Sustainable food packaging: printing on recyclable mono-PE structures with precise pressure control to preserve barrier and recyclability.
• Pharmaceutical packaging: low-solvent formulations for aluminum-based blister and foil applications with controlled residual solvent levels.
• Biodegradable labels and shrink sleeves: compatible with PLA and PET-G using zonal drying and chill-roll management to lock inks without distorting shrink properties.

Qualification & Quality Control
Manufacturing and testing protocols include gas chromatography verification of residual solvent levels, registration accuracy validation across operating speeds, energy efficiency audits and VOC leakage inspection. Key components are machined in-house and subject to established production and test procedures.
