Recently, China's newly revised "Food Safety Law" has proposed the establishment of a full food traceability system at the national level. It has set new requirements for safeguarding the safety of the food industry's entire industrial chain, and has also provided a "lock" for the safety of the food packaging industry. .
Many supermarkets have already launched scans for food sources on the fresh food market in the fresh food market. Although there are still many problems in the media exposure, such as counterfeiting or incomplete traceability of information, overall, food packaging "ID card" - two-dimensional code, indicating the origin, storage, transportation, processing to sales and other information, so that consumers feel comfortable eating is the trend.
The research and development of two-dimensional code technology began in the late 1980s and is an information storage technology. It is a new information storage technology developed on the basis of one-dimensional code. Its advantage is that it has large information capacity and does not depend on the network and database. Because of the limited capacity of one-dimensional code, its application needs to rely on the support of the network and database.
At present, the function of the two-dimensional code is expanding from the traditional anti-counterfeit demand to the marketing function based on the Internet of Things and big data. To become a fulcrum to transform and upgrade a traditional industry. In China's huge fast-moving consumer goods market, any single product has a huge amount of variable data printing needs.
