Qr code in beverage bottle and cap laser marking has been widely popularized, the food, cosmetic, pharmaceutical and other industries focus on high qr code trace, also in other industries began to spread.
So, about the qr code, how much do you know?
We consulted the laser professional engineers, the following popular science some common knowledge of qr code!
QR code includes two kinds: one kind is a common QR code is a DATA MATRIX code ♦ QR codes is characterized by can contain Chinese characters, can store content is very rich also, at the same time according to their characteristics, the code system of scanning speed faster, at home a lot of food and drink, the bottle, bottle caps, bottle have more use.
♦ DATA CODE CODE is characterized by a smaller, does not increase with the content of the qr CODE size bigger.
And regardless of the form the content of the qr code generally include the following 1, the enterprise internal to generate a sequence number, containing the manufacturers, the site of factory, specifications, batches, production date, time, flight information, etc.
At the same time, through specific coding rules, can play the role of anti-counterfeiting.
2, website information, consumers can sweep through code to jump to the corresponding url, query the authenticity or lottery and other activities, manufacturer can sweep through customer code, a certain specific data analysis.
The qr code on the package can be circulation control, convenient enterprises through qr code generated by the host databases, namely we often say 'yard' thing, can realize the product in the process of circulation.
In the supermarket, in the hands of the customer, on the side of the road shop, can use mobile phones easily scan, query to internal contains information, to manufacturer, to the requirement of products for the transregional and matching product traceability management system with better effect.
Why usually use laser to spurt the code machine qr code tag?
1 a clearer code effect and ink printing machine (
Compared to the laser printing machine has the very big advantage, higher resolution, a more neat, a dash and dot matrix font, let a person feel better at first glance, have made a certain level to ascend, and at the same time after the reaction of the material of plastic bottle itself, the laser printing will have a better color contrast, let a person be clear at a glance, the date of the period of validity, batch number, etc.
2 better adhesion is also compared with the traditional ink printing machine, printing ink adhesion tend to have defects, a firm can not better in product surface, it is easy to wipe away, is also a lot of beverage, condiment manufacturers concern.
Laser printing machine, on the other hand, it can penetrate some oil, water, directly in the lid of the surface of the plastic products form the character of laser marking, unless destroy or replace the lid, otherwise the lid character will always exist.
3 the use of lower cost ink printing machine both in the spray character date or qr code, you need to use ink, solvent, in use process need maintenance, need cleaning agent, on the one hand is the influence of the environment, ink solvents are flammable and explosive liquid, irritating odor, have certain harm to human body.
On the other hand is to use cost, laser to spurt the code machine does not need any consumable, zero maintenance, only need to plug can be used, and the new energy cars, more use of low cost is also one big characteristics.
4 lower the failure rate of ink printing machine not only need maintenance, maintenance, in use process, at the same time also face the risk of outage or failure, common situation are: chalk line leak of partial, nozzle blocking, etc.
Laser printing machine otherwise, the structure is relatively simple, basic don't need special maintenance personnel.
