Study on logistics information packaging technology of fresh food in cold chain

Abstract

The paper describes the type and operational principle of packaging for fresh food in cold chain logistics. It gives an overview on the mechanism, features, applications, and present development of the trace-ability technology (Bar Code, RFID), data acquisition technology (temperature sensors and humidity sensors), and positioning technology (GPS, GIS). The paper also analyzes problems that currently exist in technique progress, standard construction and application system, also points out the way to solve the problems in aspects of technical intelligence, improvement of quality standards, integrity of the cold chain system and logistics green in China.
