Spain-based converter Covinil has made an undisclosed investment to purchase a new solution, a K5000 2450mm vacuum metalliser, from Bobst, a Switzerland-based supplier of equipment and services to the packaging and label industries.
The newly purchased metalliser, which is an integrated solution for the conversion of aluminium oxide (AlOx) high-barrier transparent films, will help Covinil in increasing its capacity and to have the latest process innovations to explore new markets.
Covinil’s new metalliser features the complete range of Bobst process innovations, which include DarkNight for high-barrier metallised films, AluBond for high metal adhesion and AlOx for high barrier transparent films.
The solution also includes the Hawkeye pinhole detection system, which can detect pinholes and other defects for improved barrier properties.
Covinil's owner said: “We are experienced in the area of producing metallised 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 are well known in the industry for their AlOx process but as a converter, we were also interested in its behaviour during conversion processes.
“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.”
In addition, the company has bought a new AlOx optimised coating platform from Bobst Italia.
The platform includes two innovative topcoat formulations, which are applied on a new Bobst Italia coating line to provide protection and improved barrier functionality to the AlOx coated polyethylene terephthalate (PET) films.
