Solution for adhesive stability of logistics labels in high temperature and high humidity environments

During international shipping, labels must maintain integrity under complex conditions. From high temperatures (up to 60°C) in containers to humid port environments and varying climate zones during transportation, label adhesion and readability directly impact cargo tracking efficiency and customs clearance speed.

The 100*150mm thermal label is the mainstream choice for international logistics. High-quality thermal labels feature triple-protection coating (waterproof, oil-resistant, and alcohol-resistant), with thermal coating sensitivity reaching 0.12-0.15J/cm² at 25°C, ensuring clear printed images that resist fading. The backing paper typically uses 62-65g/m² glassine paper for high-speed peeling and labeling.

Logistics-grade adhesives should exhibit initial tack ≥12N/25mm and holding power ≥24 hours. Within the temperature range of -20°C to 80°C, labels should remain edge-curl-free and securely attached. For cold chain logistics, low-temperature-resistant adhesives are required to prevent failure in freezing conditions.

BPA-free eco-friendly thermal paper is recommended, compliant with EU REACH regulations. Set thermal printer concentration to medium-high to avoid faint images. Ensure packaging surfaces are clean and dry before labeling, free from oil or dust, for optimal adhesion.
