"Intelligent technology" will quickly occupy the "flexible packaging" market (II)

the intelmer liner developed by APIO company will keep agricultural products fresh and replace the ice that must be used previously. Intelmer liner technology uses pressure-sensitive film to automatically adjust the oxygen/carbon dioxide balance in the sealed carton. This breathable film is coated with side chain recrystallized polymer on one side. As the temperature changes, even if the change is very small, the film will adjust the gas density accordingly. When the temperature rises, the vegetables need to breathe more, and the film will release more oxygen and carbon dioxide. It is enough to pull in the range of 300 Newton; Come in. This technology effectively extends the shelf life of vegetables with high respiratory rate, such as broccoli, up to 17 days. Not long ago, it was adopted by Chiquita brands internati Jinan experimental machine factory as a new type of Brinell hardness tester, which is used to pack bananas

bioett ab of Sweden has developed a TTB Technology (time temperature biosensor), which can monitor the packaging conditions of perishable products in the supply chain. Its core technology is the use of biosensor tags, which have a passive radio frequency circuit. Biosensors respond to changes in temperature and time, and increase the strength of the signal. Through the portable scanner, the signal can be saved and selected, and the change of temperature can be displayed in graphic form to help the operator control on the computer. This technology is very cost-effective and can effectively manage the quality of products in the supply chain

new chemical materials

using special chemical materials is a way of intelligent packaging. For example, thermochromic ink can only develop color under certain temperature conditions. Manufacturers can print some information that consumers must know under certain temperature conditions with this ink. For example, sugar maple juice is heated in the microwave oven. After reaching a certain temperature, the word "hot" will be displayed on the package, so that consumers can understand it at a glance. In addition, there is also an ink that can be displayed when the temperature is too low, which can prevent the product from freezing

these smart packages not only benefit consumers, but also benefit the whole supply chain from warehouses to store shelves. Packaging with special ink can always remind staff whether the temperature of the cold chain is appropriate. The cost of ink is not high, but it can help improve the efficiency of the quality control system, especially for temperature sensitive food

time temperature indicator (TTI) is a sensory mechanism based on the principle of chemical reaction, including polymerization, enzyme reaction, diffusion, melting point, etc. Just like the fruit will change color when it is ripe, and then rot, giving off an unpleasant smell, the deterioration of food can also be shown in the change of packaging color by using the principle of chemical reaction. In other words, packaging can automatically display its shelf life. In France, this technology has been put into commercial application, with more than 140 products using this technology

using the sensory mechanism, it can also monitor the oxygen content in the package and the air tightness of the package. The chemical sensor is placed next to the product in the package and uses ultraviolet light to display a certain color after packaging. The chemical change of the product in the package will change the originally set color

Canadian toxin alert company has developed another application method of color. The company coated a layer of special antibodies against some pathogens on the food packaging film. These antibodies also have some staining components, which can tell consumers whether there are pathogens in the packaging

there is also a polymer, which combines two layers of porous films. One layer is coated with a layer of functional polymer, which expands when it meets acid, and the other layer expands when it meets alkali. Once the pH value of the product in the package changes, the film will expand or contract accordingly, and the pump is used to adjust the pH value


intelligent flexible packaging is not an instant commercial application, but this era is slowly approaching us. Like any other kind of transformation, it is slowly coming to us, constantly exploring between efficiency and cost

before we reduce the thickness and save materials, we may still have some resistance to the use of RFID technology. Some manufacturers even stick labels on cartons before the goods are loaded on board, but this is definitely not the concept of smart packaging. The value of tracking goods in the supply chain is obvious, especially for downstream packaging production lines. The real application of RFID can track and record inventory information, and collect the operation of the packaging line, upstream packing, etc

this is true of all innovations in smart packaging. On the surface, the smart package capacity plan of nearly 400000 tons has benefited dealers, retailers and consumers. In fact, smart packaging benefits everyone who uses it. Market research shows that consumers like convenient, safe and self-protective packaging
