Product Details

Rainbow thermal polyester label sticker material 
An intelligent signage solution that is efficient, durable and adaptable to harsh environments

Product Overview

The rainbow thermal polyester self-adhesive label is made of high-quality polyester (PET) film substrate, combined with a special rainbow gloss coating and highly sensitive thermal color development technology. It is specially designed for scenarios that require long-lasting durability, high recognition and visual appeal. Its unique rainbow luster effect presents gradient colors under light refraction, combining functionality and aesthetics. It is suitable for high-end signage requirements in fields such as logistics, retail, healthcare, and industry.

Core advantage

• Dazzling visuals enhance brand image

The unique rainbow-lustrous coating on the surface presents a dynamic gradient effect under light from different angles, endowing the label with a high-end texture. It is suitable for scenarios such as promotional labels, luxury logos, and creative packaging, enhancing the appeal of the product.

• Full environmental protection

Waterproof and oil-proof: The special surface coating can resist liquid penetration, keeping the label intact even in damp and oily environments.

Chemical resistance: Resistant to erosion by acids, alkalis, alcohol and other solvents, suitable for laboratories, chemical industries and other fields.

Strong temperature resistance: Adaptable to extreme temperatures ranging from -20℃ to 150℃, suitable for scenarios such as cold chain transportation and high-temperature production lines.

Scratch-resistant and wear-resistant: The high-strength PET base material effectively prevents label wear and tearing, extending its service life.

• High-efficiency thermal printing

No carbon ribbons are needed. It is directly compatible with thermal printers, reducing consumable costs and improving printing efficiency.

The high-sensitivity coating ensures that the printed content is clear and sharp, and text, barcodes, and QR codes can all be accurately presented.

• High transparency and beautiful design

The transparent base adheres to the surface of the product, and the invisible label effect does not block the content. It is suitable for high-end products, electronic components and glass bottle bodies.

Thermal printing technology supports high-resolution graphics and text, presenting fine barcodes and text, and enhancing the professional image of the brand.

• Persistent information preservation

The anti-oxidation design of the heat-sensitive coating avoids the fading problem caused by light and high temperature, and the information retention period is up to 3 to 5 years.

• Wide applicability

Application scenarios: outdoor equipment identification, medical device labels, industrial parts traceability, logistics transportation labels, food cold chain management, etc.

Compatibility: Supports customization in various specifications (size, shape, back adhesive strength), and is compatible with mainstream brand thermal printers.

• ental protection and compliance

Compliant with RoHS and REACH environmental protection standards, non-toxic and harmless, it is suitable for sensitive industries such as food and medicine.

• Flexibility and adaptability

It offers a variety of thicknesses (50μm-150μm), sizes and shapes (roll labels, die-cut labels) for selection, and is compatible with mainstream thermal printers (such as Zebra, Honeywell, TSC).

The adhesive backing can be either a permanent adhesive or a removable adhesive, suitable for various material surfaces such as stainless steel, plastic, and glass.

Typical application scenarios

• Logistics & Warehousing: Cargo tracking labels, waybills, cold chain temperature record labels.
• Medical Health: Test tube/sample identification, medical equipment asset management, disinfection and sterilization instruction labels.
• Electronic manufacturing: PCB board identification, high-temperature resistant process label, anti-static environment application.
• Retail & Food: Fresh price tags, shelf life management, anti-counterfeiting and traceability labels.
