The company already has a mature line of metallized film products in the market; the decision to purchase a new metallizer was due to running out of capacity and also to have the latest process innovations to open up new markets. This time, Covinil chose BOBST due to its reputation for leading innovations in the field of vacuum metallization and its process know-how.
The new K5000 2450-mm vacuum metallizer that Covinil purchased incorporates all BOBST process innovations available including: DarkNight® for high-barrier metallized films, AluBond® for high metal adhesion and AlOx for high-barrier transparent films. Naturally the package includes the Hawkeye pinhole-detection system as it is an integral part of both the DarkNight® and AlOx processes; Covinil was particularly impressed with the Hawkeye’s ability to detect pinholes and other defects for improved barrier properties as well as its accuracy in measuring optical density to improve uniformity.
In addition to the processes included on this machine, Covinil was also impressed with the BOBST Integrated AlOx-conversion know-how and the way the entire process could be demonstrated on its own PET film, resulting in high-barrier performance and excellent film transparency. In conjunction with the new K5000 2450-mm metallizer from Bobst Manchester, Covinil also purchased an AlOx optimized-coating platform from Bobst Italia. As part of this package, Covinil will have access to two innovative topcoat formulations which are applied on a new Bobst Italia coating line to provide protection and enhanced barrier functionality to the AlOx-coated PET films. Once the off-line topcoat has been applied, films can then be converted further without any significant barrier deterioration using standard equipment (i.e. printing, lamination).
Commenting on the purchase, the owner of Covinil said, “We are experienced in the area of producing metallized films, but when we needed to increase capacity, we also wanted to invest in the latest process innovations in order for us to enter new markets, in particular in the area of AlOx-coated PET films. BOBST is well known in the industry for its AlOx process, but as a converter, we were also interested in its behavior during converting. However, it was reassuring to see that the barrier properties of our AlOx-coated PET films were maintained after the application of a protective topcoat layer, which convinced us to make a further investment in a new specially adapted BOBST Italia coating line. We are confident that the investment in these two new BOBST machines, together with BOBST know-how, will give us a unique competitive advantage in the area of AlOx as the innovators in the industry.”
