The new Miniflex® 390 is a compact, versatile, and extremely easy-to-use flexographic printing unit, designed for inline printing on flexible substrates such as plastic films, paper, and laminates, both porous and non-porous.
The system is web-driven, driven solely by the material’s pull, ensuring natural alignment with the line’s speed, without the need for motors, encoders, or external electronic controls.
Pneumatic and automatic adjustments of the rollers simplify operational management and ensure consistent precision. The machine is suitable for printing logos, trademarks, recycling symbols, and small graphics (including barcodes and QR codes) directly inline, with speeds of up to 250 m/min*.
It can be installed in a vertical configuration (film from top to bottom) or vice versa and uses a two-roll flexographic inking system with a clutch wheel drive. The printing plates are attached using double-sided tape for quick changeovers.
Ink supply is through a recirculation system with a 15 or 25-liter mobile cart tank, pneumatic pump, quick-connect tubing, and an easily removable machine tray for cleaning.
The new Miniflex® 390, while maintaining ease of use, reliability, and low operating costs, stands out for a significant improvement in its speed performance. This goal was achieved through the redesign of the ink dynamics within the machine using CFD software.
