Coating & Laminating Comexi ML1 MC brings high speed EB coating
and laminating capabilities to the fore Since its founding, Comexi has consistently been strongly committed to the environment and innovation of machinery that empowers converters to develop and design more sustainable flexible packaging. Albert Chicote, business unit director, lamination at Comexi, explains how the Comexi ML1 MC fits into the company ethos.
W
ithout a doubt, an important factor of sustainable packaging includes providing machinery manufacturers, as well as the complete supply chain, new challenges, such as: tension control, machinability, printability, barrier properties, reel handling, sealing temperatures, COF, among numerous others.
In light of these challenges, Comexi, has been working towards a big number of milestones to facilitate the following transitions: standard materials to those of the new generation for our customers; coating technology to drying enhanced capabilities; and winding options to the ultimate 4.0 environment.
At present, Comexi is extremely pleased to announce the introduction of high speed EB coating and laminating capabilities for the state-of-the-art Comexi ML1 Coating Laminator.
Performance excellence has been taken for granted on the Comexi ML1, a laminator which was developed for the most demanding applications. As a result of its versatility and modularity, the ML1 is able to execute any application demanded by the market, including solvent or water-based, solventless or 100% solids, and presently EB-cured coatings, EB Over-Print Varnishes (OPV), and EB laminating adhesives.
Designed for high speeds (1,500 ft/ min), with the ability to achieve maximum productivity and reduced downtimes, the Comexi ML1 has proved to be the most profitable laminator on the market for high- speed and high-end demands.
Furthermore, the configuration of various automatic winders options (full turret shaft / shaftless, with different diameters and weights) are also possible, offering customers the opportunity to work with every type of films, including paper and cardboard. These two films are becoming more influential in the flexible packaging industry, not only as a result of their different perception of “recyclable”, but due to the rapid growth of applications
as well. Concurrently, leading chemical companies are designing numerous coatings, in order to provide a variety of barrier property grades for various films and paper, such as oxygen or water vapour; sealing capabilities or grease-proof for paper / cardboard are also included.
Moreover, and also the reason for Comexi presenting this innovation, various coatings are not only solvent or water-based nature, but comprise of EB as well. For several years, EB technology has been a key Comexi objective; this technology includes flexo, offset, and lamination. As a result, Comexi is on the forefront, particularly in reference to its product portfolio, which includes the optimum combination of an ML1 laminator with EB equipment.
Unquestionably, the addition of EB capabilities compliments the flexibility of this feature as explained by Carles Rodriquez i Nieto, vice-president of Comexi North America: “Working with Energy Sciences Inc. (ESI) on this project, has allowed us to ensure that our EB offering would have adaptability and maximum performance capabilities for the flexible packaging market. With widths up to 59inch, speeds up to 1,500 ft/min, and the
addition of a unique chill roll, among other ancillary equipment, converters will be able to run even the most extensible films and thin gauge polyethylene.”
EB-cured OPVs are specifically designed for the flexible packaging industry and have a variety of features, including coefficient of friction (COF), the lowest migration of residual components, as well as various levels of glosses, textures, scuffs, and abrasion resistance. EB OPV’s are safe for food packaging. In addition to being EUPIA and FDA compliant, as well as meeting European standards, such as the Swiss ordinance, they have ultra-low migration and extractability. It is imperative to remember that the flexible packaging market is migrating toward sustainable and recyclable packaging structures. EB OPVs allow printers and converters to lighten their packaging weight by eliminating film layers and produce surface printed structures with an EB-cured OPV, both of which protect ink as well as enhance visual and tactile effects. As a result, Comexi is leading the transition to more sustainable packaging.
