Rotogravure printing press

for plastic filmfor packagingfor BOPP film

Product Overview
The Multi-color rotogravure printing press from Shaanxi Beiren is a roll-to-roll rotogravure machine for high-speed, high-precision printing on flexible substrates (BOPP, PET, PVC, aluminum foil laminates). Configurable with 4–8 color units, it provides registration accuracy within ±0.1 mm and mechanical speeds of 250–600 m/min. The platform supports web widths from 600 mm to 2500 mm and addresses packaging and decorative printing applications requiring consistent color reproduction and minimized material waste.

Key Advantages
Designed for continuous, high-throughput production with stable color control and repeatable registration.

• Chrome-plated cylinders for prolonged surface stability
• Automatic viscosity control to maintain ink properties
• Ultrasonic web-edge guidance to prevent lateral drift
• Modular color stations (4–8) for flexible job configurations
• Compatible with solvent-based and water-based inks

Technical advantages

• Speed: 250–600 m/min depending on substrate and configuration
• Accuracy: Electronic line-shaft synchronization for instant station alignment (±0.1 mm)
• Ink laydown control: Variable cell depths for extended tonal range
• Quick startup: Servo-driven systems reduce setup waste during job changes
• Energy efficiency: Heat-recovery options in drying tunnels to lower consumption

Applications

• Food & Beverage Packaging: Suitable for high-barrier films and complex laminates (e.g., PET/ALU/PE) for retort pouches and processed-food packaging.
• Pharmaceutical Packaging: Precise tension and high-resolution printing for micro-text, barcodes and anti-counterfeit features on foil and film substrates.
• Decorative Products: Wide-web capability and heavy ink laydown for photorealistic effects (wood grain, stone textures) in laminates and flooring.

Quality, Testing and Compliance
Verification procedures include stroboscopic video inspection for registration, gas chromatography for residual solvents, adhesion testing (ASTM D3359 and Sutherland Rub), and spectrophotometer Delta E monitoring. Machines are built to meet relevant industry quality standards including ISO 12647-2 where applicable.

Manufacturing & Support Highlights
Shaanxi Beiren supplies in-house manufactured critical components, modular assembly for field upgrades (additional color stations, control-system updates), and engineering support for retrofits and commissioning.
