New at Interpack: L333 wide-format flexographic printing machine

At Interpack, SIAT introduces the new L333, a wide-format flexographic printing machine developed to increase productivity by processing a wider web.

While the current range presents the traditional L-Series range with 150 mm input tape reel width, the L333 introduces a new wide-format approach with web width up to 300 mm. This allows customers to produce more finished rolls from a single jumbo log.

For example, from a 300 mm web, the machine can produce up to six rolls of 50 mm width.

Key strengths:

• Wide-format web width up to 300 mm
• Higher output per cycle
• Up to 3 colours
• More finished rolls from one jumbo log
• Lower cost per roll
• Reduced processing time
• Adjustable spacers for different tape widths
• Maximum roll diameter: 330 mm
• Temperature management with heating or cooling according to material type
• Optional primer, release coating, corona treatment and peristaltic ink pumps
• Flexopol compatibility for in-house cliché production

The L333 is not just another model in the range: it introduces a productivity-driven approach. Instead of focusing only on speed, it focuses on output per cycle, material utilization and cost per roll.
