Recently, relevant departments in Jiangsu, Anhui and other places have received complaints from consumers, saying that the date of production of some condiments is easy to smear and fall off. After investigation, the problem of consumer complaints is not unfounded. There are many brands of condiments. There are indeed such problems.
The date of production of the seasoned food is mostly printed on the bottle body and the bottle cap, but some seasonings are wiped with ordinary alcohol cotton, the production date will be blurred, and then the wiping will continue, and the production date will be completely erased. As a whole, the date of production of condiments on the market is more standardized. Some companies use laser coding technology to make the production date firmly 'branded' on the bottle so that the production date and the bottle are not separated, not easy to fall off. Or it can be smeared and tampered; there are also condiment companies that use both inkjet coding technology and laser double-code printing to achieve the production date of the product bottle wrap and cap at the same time, ensuring that it does not fall off and is not easily altered.
How to block the 'birthday' hole? Laser printers can help
Digital printing has a history of more than 20 years in China. So far, many people in the industry have agreed that the cost performance of inkjet printing is relatively high for digital printing. Perhaps because of the low input cost of inkjet printing. , cost-effective, so inkjet printers are still favored by many food processing companies. But this type of equipment has certain defects in terms of comprehensive performance, effects, data processing capabilities, environmental protection and safety.
First of all, the ink jet printer needs to work in the state of dynamic flight. It can only be used on the food production line and cannot be operated separately. It is worth noting that this type of equipment is greatly affected by the color of the material itself, but the packaging material is not directly Affect the clarity of the code, while the code is attached to the surface of the product, easy to smear and change, which gives the unscrupulous traders a date of production, which provides a condition for the near-expired or expired foods to be 'renewed'.
Secondly, the use of single-chip control system, limited data processing capabilities, limited Chinese characters, only suitable for content, less data information, and does not rule out some text can not be printed. Finally, ink and solvent are highly volatile substances, improper use Or excessive production will produce more chemical toxic residues, causing certain pollution to the environment, and at the same time, it may penetrate into the marked object, affecting the quality and safety of food.
With the rapid development of technology, as well as the application of big data, Internet of Things, etc., laser coding technology has become the industry's development trend. Some low-end, simple, easy to smear, off-line identification equipment will be The elimination of the market, from simple assignment, data communication to the retrospective marketing of QR code, is a technological level of progress, and is also a key point for future customers' demand for coding equipment.
At present, new laser coding equipment has appeared on the market, mainly using dot matrix resident technology, which marks some important track points of the characters to be marked. Under the same capacity, the new dot matrix laser coding equipment It is faster than the traditional scribing device. Of course, more importantly, the logo is more clear and can be stored for a long time without being easily applied. Change. The coding device not only effectively solves the problem. The problem of product confusion caused by unclear identification, but also reduced the illegal production date of illegal manufacturers, infringement of the legitimate rights and interests of consumers.
It is understood that the laser jet printer introduced by Suzhou Yixin is designed with imported sealed RF CO2 laser and high-speed scanning galvanometer. It has the advantages of low consumables, excellent beam quality, good coding stability, and working life. Long, it can work continuously 24 hours a day. In addition, the laser marking equipment is clearly marked, difficult to change, smeared, easy to operate, easy to maintain, and can control different materials and different types of products by controlling the hand-held device. Laser coding.
It can be seen that in the face of the date of production marked on the food packaging, there is a problem of easy smearing and change. On the one hand, relevant departments should strengthen supervision and rectification of the market. On the other hand, food processing enterprises should upgrade the coding equipment in time. Introducing advanced laser coding technology, using professional laser coding equipment, and working together to block the 'birthday' hole.
