The multilayers barrier packaging, in a modified atmosphere, allows to pack a large number of products, increasing their shelf life and maintaining the organoleptic and nutritional properties. The know how achieved by UNION over the years, has allowed the company to optimize all the steps of this process, ensuring high quality results.
In coating technology, all materials are processed by a single screw extruder and the coating is done through the flat die and thermos-regulated cylinders of special manifatture.
In hot melt lamination, contrasting thermos-regulated cylinders are used or the foil is directly laminated in calender, by the contact of hot melt materials. Both systems ensure a perfect and a uniform adhesion of the layers over the entire width of the foil. The coating system «barrier or hot melt lamination» is applicable on existing lines and is also used for other materials such as PP and PS.
