Ⅲ. Detailed Material Introduction

Standard Coated Thermal Paper

Cost-effective general-purpose thermal stock with surface protective coating. Resists minor water splashes and light abrasion, delivering stable print quality and high barcode scan rate. Ideal for room-temperature indoor usage: shipping labels, inventory tags and retail price stickers. Not suitable for long-term submersion, heavy grease exposure or extreme low-temperature conditions.

Waterproof Synthetic PP Thermal Film (Polypropylene)

Popular upgraded tear-proof substrate with waterproof and oil-proof performance. Thermal coating is laminated onto PP film so printed content will not bleed or dissolve upon contact with water. Flexible and tear-resistant. Great for cold beverage bottles, damp packaging, refrigerated goods, outdoor parcels and products requiring frequent surface wiping.

PET Synthetic Thermal Film

High-rigidity substrate with outstanding chemical-solvent resistance, alcohol-wipe resistance, oil resistance and moderate heat resistance. Fully tear-proof. Suitable for cosmetic bottles, chemical containers, lab sample vials and industrial equipment identification. Surface print remains readable after repeated disinfectant wiping.

Freezer-Grade Thermal Material

Specially formulated facestock matched with low-temperature adhesive. Reliable performance from -40°C to 0°C. Labels resist lifting or peeling inside deep-freeze warehouses and frozen-food environments, maintaining strong adhesion even on frosty, moist surfaces while keeping printed information clear.

Removable Thermal Paper

Light-tack adhesive formula. Peels off cleanly without leaving sticky residue. Excellent choice for temporary price tags, promotional stickers, reusable containers and sample marking. No surface damage when removed.

Tamper-Evident Security Material

Special fragile facestock. The label will fragment or leave visible "VOID" marks once peeled. Provides anti-tampering and anti-switch protection. Widely used as security seals for food boxes, pharmaceutical packages, electronics and other high-value merchandise.

Ⅳ. Characteristics of Different Thermal Label Types

Thermal labels are highly versatile and widely adopted especially within the logistics & shipping industry. Images and texts are generated on label stock via thermal heat. Thanks to easy operation, decent durability and competitive pricing, thermal label rolls are a preferred labeling solution for retail, logistics, warehouse and healthcare sectors.

1. Direct Thermal Labels

Direct thermal labels are the most common and widely used thermal label variant. Images are created by thermal print-heads reacting with special thermal coating, without ink or ribbon.

Advantages

Cost-efficient: No ribbon or ink purchase required to lower your labeling expense

Simple workflow: Less frequent consumable replacement, user-friendly operation

High-clarity output: Produce legible barcodes, texts and simple graphics

Disadvantages

Limited service life: Prints are vulnerable to heat, direct sunlight and friction

Environmental constraints: Not recommended for long-term archiving or harsh extreme-condition applications

2. Thermal Transfer Labels

Thermal transfer labels work with thermal transfer ribbons that transfer pigment onto label substrates, compatible with paper and synthetic materials. Superior durability and sharp print quality make them ideal for heavy-duty industrial marking.

Advantages

Outstanding durability: Excellent abrasion, chemical, UV and water resistance for long-lifespan applications in harsh environments

Premium print quality: High-resolution graphics, barcodes and readable text output

Multi-substrate compatibility: Works with paper, synthetic films and metal substrates for diverse marking requirements

Disadvantages

Higher running cost: Extra thermal transfer ribbon procurement is mandatory

Complex maintenance: Printer and ribbon replacement demand more operational attention

Relatively slow print speed: Not optimal for ultra-high-volume fast-paced labeling jobs

3. Synthetic Thermal Labels

Synthetic thermal labels combine synthetic base materials (PP / PET polyester) with direct-thermal printing technology. Thermal print-heads form images on synthetic substrates, balancing robust physical performance and good print quality for heavy-duty scenarios.

Advantages

Heavy-duty durability: Superior waterproof, oil-proof, chemical-resistant and tear-proof performance for challenging working environments

Crisp printing: Thermal technology delivers fine prints for high-resolution barcodes and graphics

Extended usable life: Longer service cycle comparing to ordinary paper-based thermal labels

Broad applicability: Applied heavily in logistics, warehousing, pharmacy and food industries requiring tough labels

Disadvantages

Higher material cost: Synthetic substrates and advanced thermal coating raise product price

Printer requirement: Requires qualified thermal label printers with proper print-head maintenance

Environmental note: Synthetic films are not easily biodegradable
