What are the features and applications of general laser labels?

General laser labels are a type of self-adhesive label widely used in packaging printing, label, and signage fields. Their core function is to achieve anti-counterfeiting, transfer prevention, and information identification through laser technology. The design integrates materials science and optical principles, enabling the formation of durable and clear identification effects on various substrate surfaces. They are suitable for scenarios such as product traceability, brand protection, and compliance identification.

1.Technical Principles and Core Design

The core of general laser labels lies in laser engraving technology, which uses high-energy laser beams to form microscopic concave-convex structures on the surface of special coating materials, creating irreversible physical marks. Their transfer-prevention feature relies on the weak adhesion design at the bottom layer of the material. When the label is torn off, the coating splits into irreparable fragments, simultaneously revealing hidden text such as "void if removed," thus preventing secondary use from a physical perspective. Additionally, multi-color printing processes can present brand logos and anti-counterfeiting information simultaneously, enhancing visual recognition.

2.Material Properties and Execution Standards

These labels employ composite materials certified to international standards, featuring strong weather resistance and chemical corrosion resistance. The thickness of their substrate typically ranges between 0.1-0.3 millimeters, accommodating curved surface application while ensuring the precision of laser engraving. Fluorescent or thermochromic components added to the coating aid in quick authenticity verification, such as revealing hidden patterns under specific wavelengths of ultraviolet light. The production process strictly adheres to the ISO quality management system, undergoing 12 quality inspection stages from raw material testing to finished product shipment, ensuring batch consistency.

3.Application Scenarios and Operational Guidelines

General laser labels are commonly found in electronic products, pharmaceutical packaging, high-end consumer goods, and other fields. During application, the substrate surface must be kept clean and dry to avoid oil stains or dust affecting adhesion. Automated labeling equipment is recommended to control pressure uniformity, with manual application requiring sustained pressure for 3-5 seconds. It should be noted that these labels are not suitable for low-temperature environments (below -10°C) or frequent friction scenarios, as extreme conditions may affect their transfer-prevention effectiveness. Customized die-cutting services are available for specially shaped products.

4.Technological Advantages and Practical Performance

Compared to traditional printed labels, laser labels have significant advantages in anti-counterfeiting levels: their physical destruction characteristics increase counterfeiting costs by over 80%, while multi-color stacking processes can integrate more than 20 anti-counterfeiting elements. In practical use, a pharmaceutical company reduced its product diversion rate by 65% and increased market sampling pass rates to 99.2% after adopting this technology. Compliance with international execution standards ensures their acceptability in cross-border trade, currently supporting certification requirements in over 90% of countries worldwide.
