Graphic technology. Ink, paper and labels. Requirements on hot alkali penetration and resistance Ingestion-build-224916 method I cover the evaluation1 Scope This International Standard specifies test methods for penetrability and removal times of labels that have been wet glued on bottles intended to be refilled and reused, and resistance of printed labels against hot alkaline solution. Test results always deal with systems comprising of substrates, ink films and varnish films if present. This International Standard is valid for label substrates and printed labels. Label substrates include
