Intravenous therapy or I.V. therapy is the giving of liquid substances directly into a vein.  The use of a Hanger label for hanging a glass or plastic contained the liquid substance.  A built-in hanger feature for dispensing solutions typically used in hospitals or domestic therapy.  The Hanger labels made of pressure-sensitive films that provide superior durability and have sufficient strength to hang a product weighing up to 3Kg.  The additional piggyback feature allows the recording of level of dosage.
