Industry solutions for the vacuum thin-film coating of flexible packaging productsThe Bühler Leybold Optics applications portfolio
The LEYBOLD OPTICS PAK series is the answer to meet these demands: it is a robust and powerful metallization plant for tough, mass production environments. Standard applications are metal coatings on paper and plastic foil. Typically generated by aluminum evaporation, these layers act as barriers to oxygen and water vapor in addition to their decorative function; the result being a high-performance packaging material.
The latest series highlight is the LEYBOLD OPTICS PAK T machine. T stands for transparent barrier. A unique plasma-assisted thermal evaporation process allows the deposition of transparent aluminum oxide (AlOx) coatings. This enables food packaging companies to provide a product with barrier properties to keep food fresh and to provide visual transparency so that consumers can see the product inside the packaging for themselves.
