A process of cardboard and paper dry finishing by means of thermo-lamination of 1 single pre-adhered plastic film, using speed, pressure and heat applied in automatic laminating machines or conventional plasticizing machines.

o que e termolaminacao

The pre-adhered plastic film has two layers, normally one BOPP or PET film, opaque or shiny, called base film, and another thermo-adhesive layer. A temperature of 100oC is applied on the film set, and this temperature is sufficient to melt the thermo-adhesive; however, it is insufficient to change the base film surface, which keeps its physical properties. To melt the adhesive, the pressure exercised by the equipment by means of heated pass-through rolls provides the lamination with the paper or cardboard.

The Prolam thermo-lamination films BOPP Opaque and High Gloss are Corona-treated on both sides with the intention of providing better adhesion of the thermo-adhesive to cardboard and paper, as well as UV varnish applied with reserve.
