Currently, in most production processes in which there is printed ink on plastic films , the material is rejected for not complying with the final specification required or simply because they come from the initial setting for the commissioning of the machinery. Many of these residues are not recoverable printed plastic due to its high content in ink and therefore it cannot even be used to produce recycled plastic. The high content of ink significantly decreases the viscosity of the plastic and this is a problem at the time of reusing it through an extrusion process of the material.
