Important advantages of laser marking machine in food

In recent years, 'food safety' has been a hot topic.

Nowadays, people no longer only pay attention to packaging, taste, and price, but pay more attention to the safety of food. However, what is less known is that the food packaging on the market is mixed, and even the shelf life that people believe can be faked.

As an advanced laser processing equipment, the laser marking machine is applied to the food packaging industry, which will help stop the 'date game' on food packaging from the source.

An industry insider said: “Whether it’s printing or inkjet printing, as long as ink is used, it can be smeared.

The printing time information can be adjusted arbitrarily within three years.

” 　

Most people from large companies to small vendors know the shelf life of smeared food.

Only customers are kept in the dark by 'hidden rules'.

Unscrupulous companies play the 'date game' to make unlawful gains. They treat the food that is now or about to expire and put it on the market after it has been refreshed, which seriously infringes on the rights and interests of customers.

So how can we stop the 'date game' on food packaging from the source?　　 A more effective measure is to use laser marking to 'engrave' the production date and other information on the packaging.

Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece to vaporize the surface material or cause a chemical reaction to change the color, thereby leaving a long-lasting symbol. It has high marking accuracy. , Fast speed, clear symbols and other characteristics.

But many food unit manufacturers are far from it.

The main reason is that the cost is too high, and the price of the equipment is about twice that of the ink equipment.

In fact, this is not the case.

In the initial stage, the price of laser marking equipment may indeed be higher than that of ink equipment. However, in the long run, laser marking equipment can reduce production costs, reduce consumables, improve production efficiency, environmental protection, safety, and no harm to the human body. And environmentally harmful chemicals.

Then the inkjet machine needs to continue to bear the cost for the purchase of ink in the later stage.

　　 The laser marking machine can print a lot of data in a very small range. The laser can mark the product material itself with a very fine beam. The printing accuracy is extremely high, the control is accurate, and the printing content is clearly and perfectly interpreted. It has strong market competitiveness, environmental protection and safety, no corrosiveness, and completely isolated from chemical pollution. It is also a kind of intimate maintenance for operators, ensuring the cleanliness of the production site, reducing subsequent investment, and reducing noise pollution .

Working principle

The working principle of the ultraviolet laser coding machine is realized by photochemical ablation, that is to say, the high energy of the laser generates objects or Chemical reaction, which in turn forms a pattern of marking.

The wavelength of ultraviolet is only 355nm.

The extremely small spot and thermal influence (negligible) give it ultra-fine and special material marking effects, which is an inevitable choice for those high-end industries that require ultra-fine processing.

Ultraviolet laser marking is unmatched by other laser machines in terms of special materials, fine marking, fine engraving, and fine processing.

For any industry's identification information solution, it can complete the task exquisitely, and it occupies a particularly important role in the identification industry.

The above is the relevant content compiled by laser marking machine price manufacturers. Welcome new and old customers to negotiate.
