THIN FILM ADHESIVE LABELS AND METHODS OF MAKING THEREOF

摘要

Thin film labels, systems, and methods of making and using thereof are described. The thin film systems contain a label and a carrier film, where the label contains an overprint layer, indicia, and an adhesive layer. The carrier film may be coated on one or both sides with a release liner. The adhesive layer can be any suitable adhesive, such as a pressure sensitive adhesive, a fluid activatable adhesive, a heat activated adhesive, or a contact activated adhesive. The label is formed by printed or coating one or more layers of precursor material on the carrier film using standard printers. Suitable precursor materials include, but are not limited to epoxys, solvent cast films, polyurethane dispersions, such as acrylic-urethane hybrid polymer dispersions and polyester-polyurethane dispersions. After the overprint layer dries or is cured, the indicia are printed onto the overprint layer, then the adhesive is coated on top of the indicia.
