In the modern packaging industry, PET bottle caps are favored for their excellent corrosion resistance, high temperature resistance and recyclability. In order to ensure product traceability and brand image, these bottle caps usually need to be printed with various information, such as production date, batch number, anti-counterfeiting code, etc. As an advanced identification technology, CO2 laser marking machine has demonstrated excellent performance in printing identification on PET bottle caps with its high precision, high speed and flexibility.

一、Working principle of CO2 laser marking machine

The CO2 laser marking machine uses the laser beam generated by the CO2 gas laser to focus on the surface of the PET bottle cap through the optical system to form a tiny light spot. Under the control of the high-speed scanning galvanometer, the laser beam moves according to the preset pattern or text trajectory, thereby producing physical changes (such as melting, vaporization or color change) on the surface of the bottle cap to form a permanent mark. Due to the non-contact processing, the CO2 flying laser marking machine will not cause mechanical damage to the bottle cap, while ensuring the clarity and accuracy of the mark.

二、Features of CO2 laser marking machine

1. High precision: CO2 laser printer adopts high-precision optical scanning galvanometer and laser control system, which can achieve micron-level positioning accuracy and marking accuracy. This makes the logo printed on PET bottle caps have fine lines and clear edges, meeting the requirements of high-quality packaging.

2. High speed: Compared with traditional inkjet printers, CO2 laser marking machines have faster marking speeds and can achieve a single-shift output of thousands or even tens of thousands of pieces. This greatly improves production efficiency and reduces production costs.

3. Flexibility: laser marking equipments support automatic encoding, printing of serial numbers, batch numbers, dates, barcodes, QR codes and other information formats. Users can flexibly set the content and format of the mark according to actual needs to meet diverse packaging needs.

4. Persistence: Since laser marking uses physical changes to form a mark on the surface of the bottle cap, the mark has extremely high durability. It is resistant to high temperatures, corrosion, and is not easy to erase, which can effectively prevent the escape of goods and the emergence of counterfeit and shoddy products in the market.

三、 Application Case of CO2 Laser Marking Machine on PET Bottle Cap

In order to improve the traceability and brand image of its products, a well-known beverage manufacturer decided to print information such as production date, batch number and anti-counterfeiting code on PET bottle caps. After multiple comparisons and tests, the high-speed laser marking machine was finally selected as the marking equipment. In actual application, the CO2 laser marking machine has demonstrated excellent performance: fine marking lines and high clarity; fast marking speed and high production efficiency; flexible and diverse marking content to meet diverse needs; good durability of the marking and not easy to be counterfeited. These advantages make the beverage manufacturer's products more competitive in the market.

In conclusion, CO2 laser marking machine has shown excellent performance in printing logos on PET bottle caps with its high precision, high speed, flexibility and durability. It not only improves the traceability and brand image of products, but also reduces production costs and counterfeit risks. With the continuous advancement of technology and the deepening of its application, flying laser marking machine will play a greater role in more fields.
