Unveiling the World of Thermal Labels: A Comprehensive Guide

Thermal label materials have emerged as indispensable components in the commercial and technological realms, particularly in the realm of printing. This article delves into the nuances of selecting thermal label manufacturers, providing an in-depth analysis spanning product features to factory production. Explore the world of thermal labels through the following structured guide:

1.What is a thermal label?

Thermal labels utilize heat-sensitive materials to generate images or text through thermal printing technology. These labels find applications in printing temporary information such as barcodes, price tags, and product labels. The production involves exposing heat-sensitive materials to the thermal energy of a print head, inducing changes to create visible print patterns.

2.Are thermal labels waterproof?

Thermal labels are not inherently waterproof. Standard thermal labeling materials, such as thermal paper or direct thermal labels, are typically paper-based and exposure to moisture or humidity can cause labels to blur, fade or degrade.

However, sailinglabel has waterproof, oil and scratch resistant thermal labeling materials specifically designed to be more durable to moisture and other environmental factors. Waterproof or water-resistant thermal labels are usually made from synthetic materials, primarily used in such as polypropylene or polyester, which are more durable and less susceptible to damage from moisture.

If you need waterproof thermal labels, it is important to check the product usage scenarios and consult with the label manufacturer about the suitability of the label facestock and adhesive it produces, to make sure that it meets your requirements for waterproof and other properties. The following are the main scenarios for waterproof labels.
Outdoor labels: Waterproof labels are typically used for outdoor products such as outdoor equipment, sports equipment, open-air billboards, etc. These labels need to be able to withstand rain and water. These labels need to be able to withstand rain, humidity and other natural elements.
Food and Beverage: Waterproof labels are used in food and beverage packaging to ensure that labels are protected from moisture in refrigerated or frozen conditions and to maintain the clarity of the markings for traceability and information display.
Medical: Waterproofing is key in medical device, pharmaceutical or laboratory labeling where labels may be exposed to humidity, cleaning agents or other liquids.
Logistics and Transportation: Waterproof labels are important in logistics and transportation, especially in maritime or rainy conditions. They can be used to identify goods, shipping boxes or pallets and ensure that the label information is not damaged by moisture.
Industrial equipment: Waterproof labels on industrial equipment can help to identify and track equipment and keep labels legible even in wet or dusty environments.
Agricultural: Agricultural labels may need to be waterproof to cope with plant irrigation or humidity in a farm environment.
Overall, waterproof labels play a critical role in environments that require constant exposure to moisture or humidity, ensuring that label information is long-lasting and clear and not damaged by moisture.

3.How do direct thermal labels work?/how do thermal label printers work

Direct thermal labels employ a simple and efficient printing process, utilizing heat-sensitive paper or materials. Key components include label materials and a thermal print head. The process involves:

  • Label insertion into the printer.
  • Heating by the thermal print head.
  • Change in the heat-sensitive material, forming visible print patterns. Features include rapid printing speed, low cost, suitability for short-term labels, clear printing, and widespread applications.

4.Difference Between Thermal Labels and Regular Labels:

Thermal labels and ordinary labels have different purposes and use different printing technology.

  1. Printing technology:

  • Thermal labels: These labels use a thermal printing process that activates a thermal coating to form an image by applying heat to the surface of the label. No ink or toner is used.
  • Ordinary labels: These labels are usually printed using inkjet or laser printing methods by applying ink or toner to the surface of the label to form the desired image or text.


  • Thermal labels: usually more resistant to fading and blurring and are used in applications where durability is critical.
  • Regular labels: Depending on the printing method, regular labels may be more prone to fading or blurring over time.


  • Thermal labels: are usually more cost-effective in terms of consumables because no ink or toner is required.
  • Regular labels: Costs may vary depending on the type of printer and supplies.


  • Thermal labels: commonly used for barcode printing, shipping labels, etc. in industries such as logistics, retail and healthcare.
  • Plain labels: widely used for general labels, product labels and office printing.


  • Thermal labels: typically have faster print speeds than regular labels and are suitable for high throughput applications.
  • Plain labels: print speeds may vary depending on printer type.

6.Environmental impact:

  • Thermal labels: can be considered more environmentally friendly as fewer consumables are usually required.
  • Regular labels: Environmental impact depends on the type of ink or toner used.

5.What are thermal food labels?

Thermal food labels are labels designed for the food industry, especially for use in environments where temperature changes are common. These labels utilize thermal printing technology, which generates the desired image or text by applying heat to the label surface. The thermal printing process eliminates the need for ink or toner, making it a cost-effective solution for food labeling.
Key features and considerations for thermal food labeling include:

  1. Temperature Resistance: Thermal food labels are designed to withstand temperature changes, ensuring that printed information is legible under a variety of storage and transportation conditions.
  2. Direct heat or thermal transfer: Thermal food labels can be either direct heat or thermal transfer. Direct thermal labels are heat sensitive and create an image through direct contact with a heated printhead. Thermal transfer labels use a ribbon to transfer the image to the label surface, providing enhanced durability.
  3. Print quality: Labels should provide clear, high-quality printing to display important information such as product name, expiration date, barcode and nutritional details.
  4. Compliance with food regulations: Thermal food labels should comply with food safety regulations and standards to ensure that the information provided is accurate and the label is safe for use on food packaging.
  5. Adhesion properties: Labels need to have strong adhesion properties that allow them to adhere securely to a wide range of food packaging materials and prevent accidental removal during handling and transportation.
  6. Customization options: Food labels often need to be customized to include specific details about the product, brand or promotional information. Thermal labels offer flexibility in customization.
  7. Fast printing: Thermal printing is known for its fast printing speeds for high-volume food production environments where efficiency is critical.
    Thermal food labels are used in all aspects of the food industry, including labeling packaged products, inventory tracking, and regulatory compliance. They play a vital role in maintaining the integrity of food product information throughout the supply chain.
