1、Intelligent packaging that can display the freshness of food
Intelligent packaging refers to the packaging technology with the function of "identification" and "judgment" of environmental factors, which can identify and display the temperature, humidity, pressure and sealing degree and time of the packaging space.
Intelligent packaging is a trend in the development of packaging technology. Now foreign countries have invented a packaging that can show whether the interior is fresh. This package is used to package fish or seafood, using four electronic sensing devices that detect pH changes, one outside the package and the other three inside the package for contrast; if the three sensors change from yellow to red, this means that the inside has deteriorated. This kind of intelligent packaging greatly facilitates consumers' choice of goods, but also better guarantees the interests of consumers.
2、Nano-packaging technology
Perhaps one day there will be a plastic beer bottle that will not explode in high temperature. It is likely to be treated by nanotechnology.
Nanometers are the length units, at 10∧-9 m. Nanotechnology refers to the study of the properties and interactions of substances at the nanoscale and the techniques that exploit these properties. Nano packaging technology is the use of nanotechnology to nano synthesis of packaging materials, nano addition, nano modification or direct use of nanomaterials to make the product packaging meet the special functional requirements of the technology.
Compared with ordinary materials, materials made of nanotechnology have higher mechanical properties and longer service life, and can be used in special packaging, such as corrosion-resistant packaging, fire and explosion-proof packaging, dangerous goods packaging, etc. In addition, nano-packaging materials have good ecological performance, and have strong ultraviolet light absorption and photocatalytic degradation ability, which can avoid causing harm to the environment through degradation.
3、Second-generation barcode on product packaging - RFID
RFID is short for RFID technology "Radio Frequency Identification", commonly referred to as electronic tags. This is a non-contact automatic identification technology, which automatically identifies the target object and obtains the relevant data through the RF signals. RFID tags have the advantages of reading and writing, repeated use, high temperature resistance, not afraid of pollution and other traditional barcodes do not have, and the processing of data without manual intervention.
RFID the basic working principle of is: after the label into the magnetic field, receive the reader radio frequency signal, with the induction current energy sent product information stored in the chip, or take the initiative to send a frequency signal, the reader read information and decoding, to the central information system for related data processing.
RFID tags are widely used in packaging, such as the British government to achieve the goal of controlling smuggling tax evasion and shoddy fraud in the tobacco industry, the need to put RFID tags on the cigarette box.
