Bobst introduces vacuum metallizer for flexible packaging and converters

Bobst has introduced a compact vacuum metallizer for flexible packaging converters and CPP/PE film producers.

Available in widths from 1250mm to 2450mm, the new BOBST K5 VISION can handle a wide variety of different film types including heat sensitive films and thin gauge substrates.

The metallizer, which can run at speeds up to 840m/min, can be equipped with roll diameters of up to 1000mm.

Bobst said the K5 VISION machine incorporates a Ø600mm coating drum providing the largest coating window in the industry that increases aluminum collection efficiency by up to 16% resulting in less consumables, an extended boat life and a 10-15% energy reduction.

The K5 VISION features the BOBST ECO Mode designed to reduce energy consumption by up to 50% during stand-by, thus reducing carbon footprint and providing significant savings in production costs for the operators.

Additionally, the machine is equipped to handle a range of substrates including thin gauge films. It also allows quick changeover of different film types making, as required for converters.

The machine comprises pumping group with the lowest footprint. These include dry rotary screw pumps with a consistently high vacuum performance, booster pumps for maximum efficiency, and floor mounted diffusion pumps to eliminate the risk for back streaming of oil on to the film.

Bobst provides equipment and services to packaging and label manufacturers in the folding carton, corrugated board and flexible materials industries.
