3 Characteristics and Development of Information Intelligent Packaging Technology

Information-based smart packaging technology mainly refers to new technologies that reflect the contents of the package and its inherent quality and transportation, sales process information. This technology includes two aspects [2]: First, the information recording and performance of the product's internal quality impact during storage, transportation, and sales; and second, the record of product production information and sales distribution information. The technologies that record and reflect this information relate to chemistry, microbiology, dynamics, and electronics. Information-based smart packaging technology is one of the most promising packaging technologies for development.

The information-based intelligent packaging technology that reflects the quality of goods is mainly the use of chemical, microbiological and dynamic methods to record changes in the quality of goods in the life cycle of packaged goods [1]. In general, due to changes in the commodity storage environment and the packaging's internal environment, information on the deterioration of commodities is often recorded using chemical and microbiological methods, and severe drop and dumping information during transportation can be recorded through dynamic calculations. Chemical methods to show. In terms of recording changes in the packaging environment, the intelligent packaging indicator developed by Finland's VTT biotechnology laboratory has achieved substantial results. The key significance of this indicator is to have the ability to directly give information about the quality of the food, packaging and space gas, packaging storage conditions. The freshness indicator directly indicates the microbial quality of the food by reacting to new generations during the growth of the microorganism. It includes: leak indicator and preservation indicator.

The leak indicator developed by the agency is designed for MAP (modified atmosphere packaging) O2 leak detection. The indicator is based on oxygen sensitive dyes and is suitable for MAP food quality control. The agent also contains oxygen-absorbing components that can extend the shelf life of the food and prevent the indicator from reacting with residual O2 in the MAP. The indicator is incorporated into the synthetic film to further prevent oxidation of the indicator during packaging. The advantage of the O2 indicator is its irreversibility. VTT also uses laccase to catalyze enzymatic reactions to form colored products and study the composition of leak indicator. Under aerobic conditions, laccase oxidizes a variety of substrates. The composition of the visual indicator requires the production of a colored product, such as the formation of a colored product from light green to dark green from ABTS. This indicator reacts with oxygen and shows a rapid and obvious color change, which indicates the package is broken.

Preservation indicator is used to show the freshness of the product by changing the content of volatile gases such as H2S produced by meat and poultry products in the packaging. H2S and myoglobin form a green pigment, myoglobin. The quality of MAP poultry meat was controlled using the formation of myoglobin in the myoglobin fresh-keeping indicator. These myoglobin-based indicators that visually detect color changes are applied to the inner surface of the packaging material of fresh broiler platters. The color change is related to the quality of poultry meat, ie H2S gas is produced. The indicator then changes color.

Many sophisticated and expensive commodities have extremely stringent requirements for transportation conditions. Therefore, in order to avoid disputes, there is a need for a device for recording dynamic information, which records the dynamic behavior (such as falling, dumping, etc.) of information that may cause damage to the product during transportation. This device for recording kinetic information is often composed of two kinds of chemical powders that are isolated. Once the dynamics that are strictly prohibited occur, the isolation is released and the two chemical components react to each Other, showing the third color. If the receiving party does not open the product package, this record display device can be used to understand whether the product is safe during transportation.

Smart packaging that can display product production and sales information has a positive effect on the user's use of the product's performance and automatic logistics management. This smart package is generally composed of electronic chips, software, and barcodes that record information, also known as electronic packet packaging (ELECTR onICS COMBINED PACKAGING) [2-3].

The INTELLIGENT MICROWAVEABLE PACKAGE developed by RUTGERS University is an example of such packaging. This intelligent microwave heating package is a good information carrier. It integrates the information of food processing into the information code of the package. The microwave oven is equipped with a barcode scanner and a microprocessor to obtain the processing information and control the heating effect of the microwave oven. . This establishes an information channel between food, packaging and microwave ovens.

All information of the product, such as name, composition, function, place of origin, shelf life, weight, price, usage guide, warning, etc., is stored in digital form on the microchip on the package, and consumers can easily read the information. Packaging with electronic data information can cover a wide range of applications and it can be applied to almost all products including food.

The development of informatization of modern logistics puts forward higher requirements on the intelligentization of packaging, because a basic material basis for the development and management of logistics informatization is the intelligentization of packaging. Most of the information needed for logistics management should be carried by packaging. In other words, if the amount of information on the packaging is insufficient or incorrect, it will directly affect the activities in the logistics management. If there is no intelligent packaging, the scanning equipment and computer management provided by modern logistics management will be useless. . The goal of TRACEABLE TRANSPORT PACKAGING [2-3] is to develop a form of transportation packaging technology that is conducive to automated management so that transportation containers can be tracked on the circulation route, facilitating the control center to complete the The adjustment and management of transportation routes and on-line merchandise have achieved the purpose of quicker, better path-based and lower transportation cost of commodity circulation and transportation, and built an intelligent logistics system with the aid of information networks and satellite positioning systems. Smart packaging technology that Procter & Gamble is developing can predict the customer's shopping situation [5], thus optimally managing inventory. The intelligent packaging technology mentioned here is a low-cost microprocessor embedded in Tide detergent powder packaging or PIN customer cartoon packaging, so as to finally establish a seamless, integrated supply chain management. Companies can use this to track the entire process from production to sale of each product and ultimately make highly complex data sharing a reality. Based on this information, it enables factories, trucks, shelves, shopping carts, goods, and banks to seamlessly communicate information with each other without manually scanning for input. For Procter & Gamble, the shortened supply chain cycle of 2 days means that it can reduce operating costs by $1.5 billion.

Information intelligent packaging technology can reflect the quality information of packaging and commodity circulation information, which brings many conveniences to logistics management and consumers. This technology has developed with the development of technologies in other fields. The development of a variety of information intelligent packaging can bring economic benefits.

4 Conclusion

Smart packaging technology is an emerging technology branch that brings together multiple knowledge bases. Creative design and human-centered thinking are the essence of "smart packaging" technology. The emergence of intelligent packaging technology makes commodities and their packaging more human-friendly, making the human-computer interactive communication of business information easier. Intelligent packaging will play an important role in protecting consumers' rights and personal safety, protecting the market's normal order, facilitating business e-commerce, and developing novel product consumption forms, and has a very broad prospect for development.

At present, the application of intelligent packaging technology in various countries has just begun, and some technologies are still in the experimental and research stage. It can be said that this technology is still in its infancy. How to seize this opportunity to develop China's packaging industry and improve the technological content of China's packaging in order to meet the requirements of the new form of the international economy is a problem faced by every packaging person. With the changes of the times, there are more and more complex types of goods, and more and more functions of packaging are shouldered. The wave of high technology has pushed packaging to a higher level of development. It is historically necessary to develop smart packaging. (Author: Chen)
