How to Achieve One-to-one Laser Marking on Plastic Bags

In the field of plastic packaging, one-item-one-code laser marking technology is gradually becoming an important means to enhance product traceability and anti-counterfeiting capabilities. This technology achieves precise product identification and tracking by assigning a unique QR code to each plastic bag package and using a laser marking machine to permanently engrave it on the plastic surface.

Firstly, the core of the one-item-one-code laser marking system lies in generating unique QR codes. These QR codes contain basic product information, such as production batch, date, and expiration date, which are crucial for consumers to understand the product and for enterprises to manage products.

Secondly, the advantage of laser marking technology lies in its non-contact, high-speed, and high-definition characteristics. The marks produced by the laser beam on the plastic surface are not only clearly visible but also, compared to traditional printing methods, it can be marked at high speed without contacting the material, and the generated QR codes are wear-resistant, waterproof, and not easy to fade, with high durability, ensuring long-term readability even under harsh logistics and storage conditions.

Furthermore, laser marking machines are easy to operate and can be easily integrated with existing production lines to achieve automated production. This not only improves production efficiency but also reduces the error rate of manual operations. Through software control systems, corresponding QR codes can be quickly and accurately marked on each plastic bag, without consumables, and the maintenance cost is relatively low.

Finally, one-item-one-code laser marking not only enhances the brand image of enterprises but also provides strong support for market supervision and consumer rights protection. Consumers can quickly obtain product information by scanning the QR code, increasing their trust in the brand.
