Abstract

A security label comprising a paper substrate, the paper substrate being impregnated with resin, wherein there is at least 5wt%, preferably at least 10% resin in the label. In preferred embodiments the resin is urea formaldehyde and there is a hardwood to softwood ratio of at least 1.5:1. Embodiments of the invention provide small adhesive labels, less than 20cm 2, which may be used as security labels, that is, they are difficult to tamper with and remove and so may be used to demonstrate the authenticity of the goods to which they are affixed. Also disclosed is a method of fabricating such a label.
