Logistics express sheet and preparation method thereof, logistics package and logistics goods

Abstract

One or more embodiments of the invention provide a logistics express sheet and a preparation method thereof, a logistics package and logistics goods. The logistics express sheet comprises a compositelayer and an electronic tag, wherein the composite layer comprises a first surface paper layer, a metal layer and a first adhesive layer which are sequentially arranged; the metal layer is provided with a transparent structure, and the transparent structure comprises a radio frequency window penetrating through the metal layer; the antenna in the electronic tag can be coupled with the metal layerand transmit and receive electronic logistics information through a radio frequency signal. The metal layer is added in the logistics express sheet; a transparent structure comprising a radio frequency window is arranged on the metal layer; the electronic tag is arranged corresponding to the radio frequency window; an antenna in the electronic tag is coupled with the metal layer; the metal layer serves as a radiator of the antenna in the electronic tag to participate in radiation of electromagnetic waves, the radio frequency signal transceiving performance of the electronic tag is enhanced, the radio frequency signal transceiving performance does not need to be enhanced by increasing the size of the electronic tag, and the requirement for the large size of the electronic tag is lowered.

Description

technical field [0001] This document relates to the technical field of the Internet of Things, and in particular to a logistics bill and its preparation method, logistics packaging, and logistics goods. Background technique [0002] At present, with the rapid development of Internet of Things technology, electronic tags have developed rapidly in the field of logistics. Electronic tags generally refer to tags with radio frequency identification (RFID) capabilities. Based on electronic tags, the target object information identified by the electronic tag can be identified through radio frequency signals and related data can be read and written. The application of electronic tags in the field of express logistics can shorten the operation process, increase the throughput of distribution / distribution centers, improve the speed and accuracy of inventory operations, improve management transparency, and make information transmission faster and more accurate. [0003] At present, th...
