POLYMERIC FILM SUBSTRATE FOR USE IN RADIO-FREQUENCY RESPONSIVE TAGS |
摘要 |
A radio-frequency (RF) responsive tag comprising a heat-sealing substrate comprising a polyester layer, and an antenna comprising a pattern of conductive material wherein said conductive material is in direct contact with a heat-sealing surface of the substrate, and wherein the shrinkage of the heat-sealing substrate is less than 5% at 190° C. over 30 minutes; a method of manufacture of said RF-response tag. |

1. A method of manufacture of a radio-frequency responsive tag comprising a substrate, an antenna comprising a pattern of conductive material, and optionally a data-carrying means, said method comprising the following steps:
(i) providing a heat-sealable substrate comprising a polyester layer wherein the shrinkage of said substrate is less than 5% at 190° C. over 30 minutes; (ii) disposing the conductive material of the antenna directly onto at least part of a heat-sealable surface of the substrate; (iii) effecting heat-sealing between the heat-sealable substrate and the conductive material; (iv) optionally providing a data-carrying means in electrical communication with the conductive material. |
