Increase of environmental protection and healthy consciousness ceaselessly as people, requirement commodity (especially food) pack not only should the exterior is elegant, integral structure wants reasonable, should have more protect goodly pledge and prevent bogus function. Personnel of research and development also is developed in development all the time the more scientific technology that pack and the material that pack, among them the application of intelligent label most get attention.

What intelligent label points to normally at present is wireless radio frequency identifies tag, it is label domain product of new and high technology, already packed in the product nowadays in the effect with main play, have replace traditional product stage by stage label is mixed the trend of a form code.

Intelligent label includes wireless radio frequency to identify a technology (RFID) electronic label, the brand that concealment or publicizes protects the sensor of indicator or clew product condition. Electronic label basically is comprised by chip and antenna, chip basically is used at receive and conveying data, take through be read by the signal of wireless radio frequency that reader issues, reader and antenna and computer network are linked together, form an electron module, reader sends the special signal that comes from its antenna to give the electron of location ticket, computer network will convey after feedback information processing again, make administrator gets commodity information thereby.

Intelligent label is had small, thin, soft (made product can be achieved 0. 1 millimeter controls ply, size goes to nearly 20 centimeters from a few millimeter normally, but optional twist, turn is folded) advantage, data information is read take rate fast, have prevent collide read keep character, and can be read at the same time write many electrons ticket. Intelligent label can carry data, and can pass the data of the memory in its chip read card technically implement read quickly with wireless means take, return in working process but special undertake adapting to its data conveniently. Intelligent label can be accomplished when use need not connect line, beardless power source, beardless contact.

Intelligent label can help manufacturer and consumer understand commodity in real time inventory, current, protect wait for a circumstance character, have a product to differentiate, prevent a variety of functions such as bogus, guard against theft, management.

For example, a lot of food and medicines and chemical reagents pack must be below specific temperature and low pollution environment store carry, general label is unintelligible the temperature that saves with monitoring product and defend simple case, and intelligent label can carry in product lay aside timely monitoring asks to temperature in the process the temperature of sensitive easy cankered product, caution manufacturer avoids the temperature change effect to the product.
