▎ 摘　　要

NOVELTY - Manufacturing radio frequency identification (RFID) label tags comprises supplying a roll-type label paper, forming a first non-conductive adhesive layer on the upper surface of the label paper, attaching an antenna-printed inlay tag including an RFID chip on the non-conductive adhesive layer, forming a stress relieving layer made of a material for relieving stress with a conductive material constituting the antenna on the inlay tag, forming a second non-conductive adhesive layer on stress relief layer, and attaching a protective film on second non-conductive adhesive layer, forming an ultraviolet curable resin layer for protection of the inlay tag between the stress relief layer and the second non-conductive adhesive layer, coating an ultraviolet curable resin solution on the stress relieving layer, attaching and pressing the transparent film on the ultraviolet curable resin solution by spraying an inert gas between ultraviolet curable resin solution and transparent film, and curing. USE - The RFID label tag is useful for product inventory management. ADVANTAGE - The RFID label tags have excellent stress relieving properties. The method has increased productivity. DETAILED DESCRIPTION - Manufacturing radio frequency identification (RFID) label tags comprises supplying a roll-type label paper, forming a first non-conductive adhesive layer on the upper surface of the label paper, attaching an antenna-printed inlay tag including an RFID chip on the non-conductive adhesive layer, forming a stress relieving layer made of a material for relieving stress with a conductive material constituting the antenna on the inlay tag, forming a second non-conductive adhesive layer on the stress relief layer, and attaching a protective film on the second non-conductive adhesive layer, forming an ultraviolet curable resin layer for protection of the inlay tag between the stress relief layer and the second non-conductive adhesive layer, coating an ultraviolet curable resin solution on the stress relieving layer, attaching and pressing the transparent film on the ultraviolet curable resin solution by spraying an inert gas between the ultraviolet curable resin solution and the transparent film, and curing the ultraviolet curable resin solution by irradiating ultraviolet rays to form an ultraviolet curable resin layer, where a filler for increasing or decreasing the coefficient of thermal expansion of the stress relieving layer is included in the stress relieving layer, and polyimide having a coefficient of thermal expansion of less than or equal to 20-30 ppm/K and a glass transition temperature of 300-350 degrees C may be used for the stress relieving layer. The filler contains expanded graphite, graphene, zinc oxide and/or zirconium oxide. The filler is formed in a needle shape, a planar shape, a laminated planar shape or a spindle shape. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for manufacturing RFID label tags (Drawing includes non-English language text).
