A logistics bill and its preparation method, logistics packaging and logistics goods

Abstract

One or more embodiments of this specification provide a logistics sheet and its preparation method, logistics packaging, and logistics goods. The logistics sheet includes: a face paper layer, a first adhesive layer, and an A metal layer and an electronic tag between an adhesive layer; wherein, the metal layer is provided with a transparent structure, and the transparent structure includes a radio frequency window; the antenna in the above-mentioned electronic tag can be coupled with the metal layer and send and receive electronic logistics information through radio frequency signals . By adding a metal layer to the logistics sheet, and setting up a transparent structure containing a radio frequency window on the metal layer, the electronic tag is set corresponding to the radio frequency window, and the antenna in the electronic tag is coupled with the metal layer, so that the metal layer acts as an electronic The radiator of the antenna in the tag participates in the radiation of electromagnetic waves to enhance the radio frequency signal transceiving performance of the electronic tag, so that it is not necessary to increase the size of the electronic tag to enhance the radio frequency signal transceiving performance, thereby reducing the large size requirement for the electronic tag.

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...
