<P>PROBLEM TO BE SOLVED: To provide a label made of a biopolymer. <P>SOLUTION: The label comprises a self supporting sheet of a biopolymer (preferably cellulose (e.g., regenerated cellulose), cellulose acetate and/or PLA (polylactic acid)). The sheet is substantially transparent to visible light when uncoated, and is characterized in that the sheet comprises: (a) a first coating on at least one surface thereof to aid printability thereon; (b) a second coating comprising an adhesive dispersible in an aqueous medium; and (c) optionally a third coating to modify water permeability through the sheet. The labels are to be applied to articles such as glass containers. Preferred labels are wet glue cellulose labels for example where the first coating also comprises a copolymer of vinyl chloride and vinyl acetate to aid water permeability and hence rapid drying of the label on an article. <P>COPYRIGHT: (C)2009,JPO&INPIT |
