Abstract
(EN)
Method for removing ink printed on plastic film comprising various physical/chemical treatments. The main steps in the method are: conditioning of the material, grinding, removal of ink from the film, washing the film, recovering the cleaning solution, recovering the pigment and drying the film. As a result of the method, it is possible to obtain, first, an ink-free plastic film and, second, the pigment. Said products may be reused in industry, thereby enhancing the value chain of the product.
