Smart label refers to a kind of matrix barcode recognized by light sensor, which is called two-dimensional barcode in Chinese, and the English name is QR code, which was originally adopted by the Japanese automobile industry. Two-dimensional bar codes are used to connect items and related information records: the coded information in the bar code can have 4 standardized types of data (that is, numbers, letters, English and Chinese bytes), or by supporting extensions, connect almost any type of data Network data.
At present, there are three main types of smart tags: one is interactive smart tags, which usually indirectly exchange data between the sender and the tag through the radio frequency identification function, and is often used in intelligent transportation and logistics; the second is live source smart tags, That is, the label can generate activities and respond to events after scanning, or change the surrounding environment in some way, which is common in food packaging labels; the third is indicative smart labels. Its main function is to indicate that the event has occurred. If the marked point has been exposed to poisonous gas, radiation, sunlight, exceeded the time limit, and was damaged, it is often used as a warning sign. Smart tags can also be used to track information about the location of scanned codes.
The networking and informatization of the intelligent society are the megatrends of today's world economic and social development. Intelligent information technology centered on the new generation of network technology, virtual computing and big data technology provides creative tools for expanding human capabilities and developing a smart society; and the popularity and application of smart tags have greatly improved humans, society and commodities The readability, relevance and availability of information make the intelligent society at your fingertips.
Food packaging labels introduce raw material traceability in the production process, batches can be checked in real time in circulation, and consumer terminals can see product information at a glance-relying on a small two-dimensional code can achieve full traceability of food information. Sweep, information is available ".
The raw materials provided by the raw material suppliers are provided with a two-dimensional code label, and the label records the raw material manufacturer, the use period and other information. The food production factory reads the QR code when the raw materials are put into the warehouse and records the raw material production information into the database. Put a two-dimensional code label on the raw material. The two-dimensional code label includes the raw material number, raw material name, storage date, supplier and other information.
When formulating a production plan, the plan includes the name of the production product, the number of the modulation container, the raw materials used, the weight, the input sequence, and the raw material number. Enter the content of the production plan into a two-dimensional code, and affix the label with the code to the separate pocket.
Read the QR code on the packaging bag, and follow the instructions displayed on the computer screen (for example, load the soybean with material number 051 into 20kg) and load the raw materials into the packaging bag. Then read the QR code on the raw material bag and transfer the raw material data to the computer.
The raw materials are poured into the modulation container, and after the production is completed, the packaging time and the packaging equipment number are marked on the packaging. The manufacturing data at this time are: product name, adjusted container number, manufacturing date, manufacturing start time, manufacturing end time, packaging equipment number, etc.
The manufacturing time and packaging equipment number of each batch of food are recorded in the database. According to the packaging time and packaging equipment number printed on the food bag to judge the number, the final use of raw material information can be specified.
As early as 2000, the China Article Coding Center actively tracked international food safety traceability-related work and introduced the concept of food safety traceability to China as early as possible. For more than 10 years, through continuous research on traceability technologies and item coding schemes in line with China's national conditions, the food safety traceability system with barcode technology as the core has achieved certain results.
According to reports, in order to promote China's food safety traceability standardization, the China Article Coding Center has successively completed the formulation of multiple implementation guidelines such as the "General Specification for Food Traceability" and "Code for the Code and Labeling of Food Traceability Information". This has played a positive role in improving China's food quality safety and traceability system, and also accelerated China's integration with international standards.
With the rapid development of cities, the potential for urban intelligence is increasing: use advanced smart label technology to collect more and more accurate data, analyze data more intelligently, and transmit data through more effective network connections, ultimately providing citizens More economical, safe, effective and personalized service.
The disposable diaper industry felt the explosion of the baby boomers in the 1970s. The upsurge led to quick diaper design improvements and lower prices to the consumers. The 1970s also introduced a new fastening system with new paper types.
Adding an elastic stretch to the waist of Disposable Diapers in the early 1980s helped the fit of the diaper. The 1990s added many new features to the Baby Diaper, such as mechanical tapes in the form of Velcro, and other types of hook and loop. In March of the year 2000, the first degradable diaper was introduced.
Baby Diapers could either be made out of terry toweling fabric or layers of absorbent cloth. Cloth baby Diapers can be made of cotton. Cotton has a natural wax that sometimes makes it difficult to absorb wetness. Cloth baby diapers are usually washed with detergent and water, as soap can make the diaper less absorbent. Modern Disposable Baby Diapers are usually made of a cloth-like waterproof exterior, a moisture-wicking inside layer, and an absorbent inner core. The inner core is usually made of a dried hydro gel. Early disposable baby diapers in the 1950s were made of layers of tissue paper, until the 1960s when pulp mill was used.
