A method for recovering polymer from printed glycol-modified poly(ethylene tefephtalate) (PETG) substrates, comprising the steps of: providing a printed PETG substrate with the print layer comprising pigments and/or dyes dispersed in a binder matrix; chopping the substrate into irregular strips and; treating the chopped substrate with a treating composition; wherein the treating composition is an aqueous azeotrope of an organic low molecular weight, polar solvent selected from the group consisting of ketones, aldehydes, alcohols and esters.

The invention is directed to a process for the making of a product out of laminated composite material. The process in general comprises preforming at least one layer of material such that it corresponds to a surface of a part; applying layers of fibers to the preformed layer of material; and bonding the fibers by a resin to form a laminated composite material.

The invention relates to a method to deink and/or to delaminate plastic material, preferably to a method to deink and delaminate plastic material in a single step. The method comprises the step of contacting the plastic material with an amine or a composition comprising said amine, wherein the amine comprises a nitrogen atom having at least one hydrocarbon substituent comprising an acyclic or cyclic alkyl group. The total number of carbon atoms of all hydrocarbon substituents of the nitrogen atom is at least (5).

The present invention relates to a method for removing ink printed on a plastic film comprising various physical/chemical treatments. The main steps in the method are: conditioning the material, grinding, removing 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, on one hand, a plastic film free of ink and, on the other hand, the pigment. Said products may be reused in industry, thereby enhancing the value chain of the product.

A panel for a home appliance and a manufacturing method thereof are provided, in which manufacturing time is reduced and chemical resistance is improved in such a way that a urethane coated layer is formed by using solvent-type urethane paint on a surface of an injection-molded part defining a portion of an appearance of a home appliance; and a printed layer is formed on the urethane coated layer by printing letters and symbols using a UV printing ink which may be cured through a cationic curing method.
