Stack Type Flexographic Printing Machine For Paper Bags
High-Precision Stack-Type Flexographic Printing Press | Professional Paper Bag Production Solutions
Engineered for manufacturers in retail, food packaging, pharmaceutical, and industrial sectors, our Stack-Type Flexographic Printing Press balances industry-leading precision with a compact, high-efficiency design. Whether you are scaling high-volume cycles or managing complex multi-color branding, this machine provides the rigid reliability required for modern production.
Why Choose Our Stack-Type Flexographic Press?
High-Precision Registration System
Each printing station is mounted on a stress-relieved cast iron frame and utilizes a helical gear drive system to minimize harmonic vibration at high speeds. With independently adjustable printing pressure and longitudinal/lateral registration, the machine achieves accuracy within ±0.15mm.
- Operational Benefit: Guarantees perfect logo alignment and consistent print quality, significantly reducing scrap rates during setup.
Versatile Tension Control for Diverse Paper Grades
To handle substrates from 40g to 250g-including white/brown kraft, coated, and recycled papers-the system features a closed-loop tension controller (magnetic powder brake or servo-driven) with ultrasonic diameter sensing.
- Operational Benefit: Ensures constant web tension, effectively preventing wrinkles, web wandering, and misregistration.
Chambered Doctor Blade System
The press employs a closed-chambered doctor blade system paired with high-line-count ceramic anilox rollers.
- Operational Benefit: Delivers precise ink metering and consistent viscosity, ensuring crisp text and uniform solid areas while reducing VOC emissions and ink consumption.
Optimized for Fast Job Changeover
Engineered to maximize machine utilization and OEE (Overall Equipment Effectiveness):
- Independent Accessibility: Rapid plate cylinder replacement.
- Pneumatic Pressure Modules: Minimizes mechanical reset time.
- Streamlined Cleaning: Efficient ink circuits drastically reduce downtime between job changes.
Compact Vertical Configuration
The vertical stack design maintains a footprint length of under 4 meters, ensuring full 360-degree accessibility for maintenance.
- Operational Benefit: Empowers converters to maximize production capacity within limited workshop space.
Robust Mechanical Durability
Built with high-strength steel and industrial-grade bearings, this press is designed for continuous, high-load operation. The rigid frame construction minimizes long-term wear, extending the service life of the transmission system.
