Comexi Group targets flexible packaging
The Catalan firm presented the Flexo F2 platform including the F2 MC and F2 MB flexographic presses, Offset CI8 for offset printing, Acom R2 rotogravure press, the Nexus ML 1 multi-laminating machine and its slitting and rewinding range.
Water-based ink
Comexi Flexo F2 makes it possible to print with water based ink with high speed, on the obverse and reverse, maintaining the impression quality of the printing system.
The Flexo F2 MC flexographic press is designed on the basis of the Flexo F2 MP model.
It is available in printing widths ranging from 870mm to 1270mm, eight colours and offers printing developments up to 800mm.
It runs at up to speeds of 400m/min, and can be applied to substrates such as plastic film, paper and laminates.
The Flexo F2 MB flexographic press is designed on the basis of the FW model, taking into account features of the F4 and F2 machines.
The machine is for the shortest runs and is available in the same printing widths, colours and printing development specifications as the F2 MC.
Offset technology in flexible packaging
The firm claims its Offset CI8 offset printing machine allows customers to print with offset on flexible packaging film.
Comexi said it responds to challenges in the flexible packaging printing sector such as print quality, time to market, costs and the environment.
It overcomes the drawbacks of offset printing on non-absorbent and stretchable materials thanks to the central drum.
It uses electron beam (EB) curing technology, allowing solventless cured inks without photoinitiators compatible for food packaging.
Other launches include the Acom R2 for the rotogravure printing sector, with web video, crown treater or viscosity control and the Nexus ML 1 Coating and Laminating line designed to produce turret laminating, triplex and multi-layer products.
Proslit CingularLaser
Comexi said the patent-pending CingularLaser technology aids its slitting and rewinding equipment.
Common in-line laser processes include micro and macro perforations for the transmission of CO2 in packaging for fruit and vegetables, easy open systems for packaging such as stand-up pouches, expiry dates and the printing of alphanumeric codes.
CingularLaser increases efficiency and productivity of in-line processes were laser systems are used, claimed the firm.
The slitting and rewinding machines can make 400m of micro perforations measuring 50µ to 300µ per minute, and 150-200m of macro perforations of up to 6mm/min.
It can add easy open systems to packaging, using discontinuous lines in cross or web direction at speeds of 200-400m/min depending on the system; and add barcodes, QR codes or numbers.
