Coating of heat-sealing wax and varnish

Heat sealing coating (wax-lacquer-varnish) allow the package to be heat sealed (heat sealing). This system provides for a combined effect over time of pressure and heat so that the layers of wax or varnish fuse together for a stronger seal.

Coating is carried out in line during the printing (indicated for application on partial areas) and/or on a specific machine (total coating).
