Coating the substrate with glue (laminating) or varnish (coating or printing) ,, is performed by photogravure using a deep-engraved cylinder (called a screen), then passing the film through a drying tunnel to evaporate the solvents or water. .
Techniques : photogravure or 5 cylinder system
Deposition : 0,5 to 4 g / m²
Substrates : films from 6 à 175 microns – papers from 4toà 300 g / m² – Aluminum from 9 micronmicrons
REXOR is supported by an R&D department for developing a comprehensive range of functions delivered by its varnishes : colour, printability, sealability, oxygen or steam barrier, contact with foodstuffs, reflectance, authentication…
