Vacuum metallizing system EXPERT K5

plastic filmfor paper

Overview The next generation BOBST EXPERT K5 Metallizer is the first automated metallizer designed for the flexible packaging industry. It is optimised for sustainable substrates including BOPE, MDO PE, CPP, paper and low-temperature heat-sealable BOPP films. The system integrates AI-assisted process control for reproducible deposition and remote support.

Key benefits

  • New operator console with consolidated controls and intuitive HMI
  • Automatic selection of optimized settings for different materials and processes
  • Remote support capability via BOBST iMA and BOBST Connect
• Outstanding performance
  • Improved metallized roll quality through increased automation
  • Potential output increase up to 100 tonnes per year
  • Capacity for roll diameters up to 1,270 mm
  • Largest coating window in the industry with ~16% improved collection efficiency
  • Industry-leading 700 mm coating drum diameter
  • Incorporates BOBST's proven winding mechanism
• Lowest production costs in the market
  • Shorter production cycles increase the number of rolls per day
  • Up to 20% savings in production costs
  • High machine availability and uptime
  • Total Cost of Ownership (TCO) typically reduced by 10–15%
  • TCO reduction up to 25% versus competitors in selected cases

Features

• Intuitive and easy to operate: New operator console with consolidated controls; more intuitive HMI; BOBST iMA automates and controls deposition.
• Metallizing: Largest coating window and 700 mm drum improve collection efficiency by ~16%; High Deposition (HD) source design supports high deposition rates up to 4.0 OD.
• Automatic Sequential Control (ASC): Speeds startup with minimal operator involvement; unique in the industry.
• Faster venting and pump-downs: Reduced production cycle and increased rolls per day.
• Improved winding: Direct drives on winders, durable off-the-shelf shaft vacuum seals for easy replacement, and proven winding mechanism.
