BOBST has announced that its BOBST SelectMet system incorporates BOBST F&K heritage flexo printing technology into a BOBST vacuum metallizer.

This is claimed to be a simpler and more cost-effective alternative option to the conventional De-metallization process as it does have the the complexity of special lacquers and chemical baths.

The BOBST SelectMet process operates at speeds of up to 400m/min on the BOBST General K4000 platform, thereby offering greater flexibility as one machine can be used for two processes - standard aluminium metallization and selective metallization - without compromise.

SelectMet is available in the regular metallizer widths in the converting industry: 1250mm & 1650mm.

The flexo printing unit is placed inside of the vacuum chamber and the print head position can be moved accordingly, based on which process is to be operated. For selective metallization, the print head moves towards the coating drum and then retracts back to a home position away - from the film webpath for standard metallization.

The inline vacuum metallizing process comprises special printing oil which is applied at room temperature to the web in a thin layer to generate the required pattern. Due to the low volume Anilox Cells, minimum oil is consumed (down to less than 0.5g/m2).

Further feature is that printing sleeve can be quickly and easily changed.

BOBST SelectMet offers a wide range of added-value applications for specialist converters such asi Innovative decorative packaging films, stripe metallization; in-register selective metallization onto pre-printed webs and anti-counterfeiting applications.
