Thermal paper is widely used in cash registers, label printing, and various receipt applications. Selecting the right thermal paper is crucial for ensuring print quality, durability, and safety. When making a choice, you need to consider key parameters such as moisture resistance, coating quality, color rendering, and wear resistance. Here’s what you should know to make an informed decision.
The moisture resistance of thermal paper determines how well it performs in wet conditions. Standard thermal paper coatings can dissolve when exposed to water, causing the printed text to blur or disappear—this is a common issue with receipts soaked in rain. If your application involves exposure to moisture, such as cold-chain logistics or outdoor labeling, opt for thermal paper with a waterproof coating to maintain print clarity and longevity.
Coating Quality: The Key to Print Performance and Safety
Traditional thermal coatings often contain bisphenol A (BPA), which is cost-effective but has been restricted in some regions due to potential health risks (such as in the EU). For applications requiring food safety compliance, such as takeout receipts, choose BPA-free coatings made with phenolic or acrylic resins. These alternatives meet food contact safety standards but may be slightly more expensive.
A poor-quality coating can lead to printing defects such as stains or uneven fading. You can test coating quality by lightly scratching the paper with a fingernail—high-quality coatings will not flake off easily and will display consistent color formation.
Color rendering affects how quickly and clearly prints appear and how long they remain legible.
Different thermal printers operate at varying heating temperatures, typically ranging from 60°C to 100°C. Low-temperature-sensitive thermal paper is ideal for portable printers, while high-temperature-sensitive paper works better for industrial printing applications.
Color Stability
For documents requiring long-term readability, choose thermal paper with enhanced color stability to prevent fading over time.
The durability of thermal paper affects not only print quality but also the longevity of both the paper itself and the printing equipment.
Thermal paper typically ranges from 90 to 110 gsm (grams per square meter). Thicker paper offers better tear resistance, making it more suitable for applications that require enhanced durability, such as shipping labels and high-use receipts.
High-quality thermal paper reduces wear on printer heads, preventing premature damage and extending the lifespan of thermal printing equipment.
Selecting the right thermal paper depends on your specific application and environmental conditions. If you need moisture resistance for outdoor or cold storage use, opt for waterproof thermal paper. For food-related printing, ensure BPA-free coatings for safety. Consider paper thickness and wear resistance if durability is a priority. By focusing on these factors, you can optimize both print quality and operational efficiency.
