Corona and other treatments according to MeRo Care and attention as key of success

Tuscany-based company owned by the Mennucci family, MeRo has successfully built up over the years an excellent reputation in the field of systems for corona treatment, specialising in the production of corona treatment machines for a wide range of applications and supplying system manufacturers like the German company Brückner. One of the sectors on which MeRo has focused on is that of lines for biaxially oriented films, and it is the official supplier of corona treatment to Brückner, with whom it has established a thirty-year plus partnership. Moreover, MeRo also works directly with users, deploying its expertise to identify and roll out the most suitable solution. The BOPP films core business is complimented by the converting sector with applications on printing and lamination machines, extrusion coating and coating machines. Other historic sectors for MeRo are the cast field, especially cast polypropylene films, where the company can draw on the expertise recognised by major European manufacturers, and the blown films. In addition to corona treatment, the company offer also includes vacuum plasma and atmospheric plasma treatment systems. The latter is a variation of the corona treatment which achieves better results on certain types of films, guaranteeing a longer duration of the surface tension and, thus, better adhesion of inks, glues etc. The vacuum plasma treatment systems operate in high vacuum conditions and the surface treatment takes place between the unwinder and metallisation phase. This makes it possible to achieve better adhesion on metal or other coatings of aluminium or silicon oxides, resulting in better barrier properties. Recently, there has been a trend, especially in the food packaging sector, to create a transparent coating as an alternative to the aluminium one, using aluminium or silicon oxides specifically to obtain transparent barriers. Another application in the packaging sector is the use of induction cap sealing machines, employed in the bottling sector. MeRo is one of just a handful of companies in Italy that produces this type of machinery which places a seal under the cap to create a barrier and prevent leakages, which is used, for example, in packaging for milk, fruit juice and sauces, as well as engine oil and fertiliser. The Italian company has opted for an approach centred on the constant updating of its offer, immediately applying the latest innovations in components and electronics to its production line. In corona treatment, the company efforts have always focused on ensuring quality, reliability and robustness of generators and discharge stations. Another of the company strong points is the wide selection of generator powers available, ranging from 1 to 125 kW (over 25 sizes), together with the possibility of choosing from over 40 different discharge stations depending on the application (cast, blown, converting, extrusion coating etc.). By combining different size generators with the most suitable discharge station, it is, therefore, possible to offer a customised and “made-to-measure” solution for the specific application. Furthermore, the company has always focused on electronic management. It was the first company to integrate the recipe corona treatment management system on rotogravure and laminating machines, thus avoiding the need to periodically adjust the various parameters based on the film and treatment required, which has proved particularly useful in converting processes. Another advantage offered by MeRo is the company flexibility in adapting the configuration of its devices to existing machinery layout; a capability that is highly appreciated by manufacturers. www.mero.it
