Returnable packaging for UV-curable inks

Abstract

A recyclable package for ultraviolet cured ink. The recyclable package comprises: a paper package layer (2) that is a sealed flexible package container and is used for accommodating the ultraviolet cured ink; a hydrolysable coating (1) that is coated on an inner surface of the paper package layer (2); an anti-ultraviolet package layer (3) that is wrapped on an outer surface of the paper package layer (2), exhibits a sealed structure, and is used for obstructing ultraviolet from entering into the interior of the anti-ultraviolet package layer (3) and causing the ultraviolet cured ink to be dried and cured, and for obstructing water molecules from entering into the interior of the anti-ultraviolet package layer (3) and affecting the performance of the ultraviolet cured ink.

Description

technical field [0001] The invention relates to the technical field of ink packaging, in particular to a recyclable package for ultraviolet curable ink. Background technique [0002] Ink is a kind of fluid substance with a certain viscosity, which is uniformly dispersed in the binder by pigment particles, fillers, additives, etc. [0003] Inks can be divided into volatile drying inks, permeation drying inks, oxidative polymerization inks, two-liquid reactive inks, and ultraviolet curing inks according to the main drying methods. [0004] Because of the anti-oxidation, anti-volatility, anti-ultraviolet and other requirements required for ink storage, most traditional printing inks are packaged in metal barrels or plastic barrels with hard seals, resulting in manual removal of ink from metal barrels or plastic barrels during printing operations. Transferred to the ink fountain pool, and because the ink is in direct contact with the metal bucket or plastic bucket, the ink in t...

Problems solved by technology

[0004] Because of the anti-oxidation, anti-volatility, anti-ultraviolet and other requirements required for ink storage, most traditional printing inks are packaged in metal barrels or plastic barrels with hard seals, resulting in manual removal of ink from metal barrels or plastic barrels during printing operations. Transferred to the ink fountain pool, and because the ink is in direct contact with the metal bucket or plastic bucket, the ink in the metal bucket or plastic bucket cannot be completely cleaned up, and the residual ink is cured in the metal bucket or plastic bucket, these have cured latex Ink-like waste is non-flammable and toxic

Therefore, these wastes cannot be incinerated for harmless treatment, and the use of solvent decomposition will cause air pollution due to the volatility of the solvent.

Therefore, based on the current ink packaging, there is no effective and environmentally friendly recycling path
