Product Details

Laser printed water-sensitive red sticker paper is an innovative label material that combines intelligent color-changing technology with high-precision printing performance. It is specially designed for scenarios that require waterproof warning, anti-counterfeiting identification, or environmental sensitivity. Its core feature lies in: it shows a red warning label when it comes into contact with water and returns to its original color after drying. This not only ensures clear and readable information but also conveys emergency alerts through intuitive visual changes. It is an ideal choice for fields such as food packaging, logistics transportation, medical supplies, and outdoor equipment.

Core Selling Point

• Intelligent color change, warning upon contact with water

By adopting a special water-sensitive coating technology, when the label surface comes into contact with moisture (such as liquid leakage or a humid environment), the preset pattern or text area will quickly turn red, creating a distinct warning.

The color automatically returns to normal after drying, and the humidity changes can be repeatedly monitored to achieve long-term dynamic monitoring.

• High-compatibility laser printing

Compatible with all kinds of laser printers, the printing effect is clear and sharp, without smudging or fading, ensuring the accurate presentation of barcodes, text, logos and other information.

The surface is available in matte or high-gloss options to meet the texture requirements of labels in different industries.

• Strong Adhesion & Durability

The back adhesive is made of weather-resistant acrylic glue, which adheres firmly and is suitable for various material surfaces such as paper, plastic, metal and glass, and is not easy to fall off.

The base material is waterproof and tear-resistant. Even if it changes color upon contact with water, it still maintains the integrity of the label, preventing information loss.

 

Multi-functional scene application

Anti-counterfeiting and traceability: The invisible water change feature can be embedded with anti-counterfeiting labels, and consumers can verify the authenticity of the product through simple tests.

Logistics monitoring: When packages are exposed to rain or leakage, the labels will show color to quickly locate the transportation responsibility link.

Medical safety: If the packaging of a drug or medical device changes color due to moisture, it indicates abnormal storage conditions.

Outdoor equipment maintenance: The labels change color after being exposed to rain, assisting inspection personnel in promptly identifying potential hazards.

Precautions for Use

• Store in a cool and dry place, away from direct sunlight or high temperature and humidity.
• Before printing, make sure the printer temperature setting matches the paper type (it is recommended to conduct a small sample test first).
• It needs to be used in conjunction with a laser printer. Inkjet printing may cause the coating to fail.
