In the food packaging industry, the accuracy and durability of product identification are crucial to ensuring food safety and achieving product traceability. In recent years, Laser Marking Machines have emerged in the application of marking on food packaging bags with their unique technical advantages, gradually replacing traditional inkjet printers and becoming the new favorite in the industry.
一、 Advantages of laser marking machine
1. High precision and high speed
The CO2 Laser Marking Machine uses laser beam as a processing tool. By precisely controlling the moving path and power of the laser beam, it can achieve micron-level marking accuracy on the material surface. This high precision not only ensures the clarity and readability of the marking content, but also makes it possible to print complex patterns such as QR codes. At the same time, the laser marking machine has the advantage of high speed and can complete the marking of a large number of packaging bags in a short time, greatly improving production efficiency.
2. Permanent marking
The marking left by the laser marking machine on the food packaging bag is permanent. The laser beam acts directly on the surface of the material, and the marking information is permanently engraved on the material through melting, vaporization or chemical reaction. This marking method is not easy to wear and fade, and it can remain clear and readable even in harsh environments, ensuring the authenticity and traceability of food information.
3. Environmental protection and pollution-free
The laser marking equipment adopts a non-contact processing method, and does not require the use of easily polluted consumables such as ink. Therefore, no harmful substances will be generated during the marking process, which meets the hygiene standards of the food industry. At the same time, the laser marking machine will not generate noise and dust pollution during its operation, providing better protection for the production environment.
4. Obvious anti-counterfeiting effect
The logo printed by the high-speed laser marking machine is unique and anti-counterfeiting. Since laser marking directly engraves the logo on the surface of the material, it is difficult to tamper with and counterfeit. This provides strong technical support for the anti-counterfeiting logo on food packaging bags.
二、 Comparative analysis of laser marking machine and inkjet printer
1. Marking effect
The logo printed by laser marking machine is clear, permanent and indelible, while the logo printed by inkjet printer is clear but easy to erase and change. In addition, laser marking machine can print complex patterns and QR codes and other information, while inkjet printer is subject to certain limitations.
2. Production efficiency
Flying Laser Marking Machines are efficient and fast, and can complete the marking of a large number of packaging bags in a short time. Although inkjet printers can also achieve high-speed marking, they may be affected by factors such as ink clogging the nozzle, thus affecting production efficiency.
3. Environmental protection
Laser marking machines do not need to use consumables such as ink that are easily contaminated, so they do not produce harmful substances and waste. Inkjet printers need to use consumables such as ink, which may produce certain pollution and waste during the production process.
4. Cost and maintenance
The one-time purchase price of a Laser Coding Machine is high, but its later use cost is low. Since no consumables are required and the failure rate is low, the maintenance cost is relatively low. Although the one-time purchase price of an inkjet printer is low, its later use cost is high. Consumables such as ink are a long-term use cost, and the printer may need frequent maintenance and servicing.
In summary, laser marking machines have significant advantages in the application of marking on food packaging bags. With the continuous advancement of technology and the continuous expansion of application fields, Flying Laser Marking Machines will play a more important role in the future, providing strong support for the transformation and upgrading of the food packaging industry and green development.
