Abstract
The preservation of perishable products to maintain their quality is of paramount importance for food safety and security, and is attracting more attention due to increasing concerns regarding food quality, healthcare, and quality of life. Advances in technology and materials in recent years have led to the development and implementation of intelligent packaging for perishable products that can monitor or even control their quality in a supply chain. In this paper, the techniques used in intelligent packaging (i.e., indicators, sensors, and identification technology) and the major printing methods for fabricating electronics (i.e., inkjet printing, screen printing, and gravure printing) are reviewed with a focus on the packaging of perishable products. Although the high manufacturing costs pose a major challenge the commercialization and large-scale deployment of perishable products, it is expected that the technological progresses in printing electronics will significantly reduce the manufacturing cost of intelligent packaging to a threshold of acceptance by markets. In addition, the broad applications of intelligent packaging can facilitate the traction and monitoring of perishable products for better control of the product quality and improved management of the supply chain.

Summary
Perishable products such as seafood, fruits, and vegetables are important items used in the daily live so many people. Researchers primarily focused on active packaging, in recent years advances in information technology and demand on effective management along the supply chain have led to a shift in research focus to intelligent packaging [6,8]. There is a strong need for the development of intelligent packaging for the perishable product industry to allow for the improved protection of product quality and reduced economic losses. The basic functions of an intelligent package include tracking the products, monitoring the surrounding environment, and communicating with the backend system or consumers. Proposed that intelligent packaging systems must include three main technologies, i.e., (i) indicators, a more convenient way of informing consumers about the quality of the food; (ii) data carriers, for storage and distribution of data including tracking; and (iii) sensors, for the rapid and accurate quantification of the analyses [4].
