Document Type and Number:
WIPO Patent Application WO/2012/151291
Kind Code:
A3
Abstract:
Apparatus and method for removing an ink image from a plastic substrate, particularly a plastic container such as a cup, are provided. A solvent capable of solvating the ink image is utilized in order to de-ink articles so that they can be recycled and re-imprinted thereby reducing waste associated with printing line start up. As the articles may be intended for use with food and beverage products, a safe and non-toxic solvent may be selected. However, to ensure that the article is not contaminated with foreign materials prior to human use, the de-inked article may undergo a rinse and drying operation to remove solvent residues and UV light treatment to eliminate any harmful microorganisms that may be present on the article's surfaces.
