How to Choose the Most Durable Thermal Paper? Testing Methods Revealed

If you rely on receipts for customer service, accounting, or legal records, durability matters. At MilaMima, we’re often asked: “How do I know if my thermal paper will last?” In this blog post, we’ll walk you through the science of thermal paper durability, key testing methods, and how to choose the right rolls for your business.

Why Does Thermal Paper Durability Matter?

Thermal paper might look similar across brands, but not all rolls are created equal. Durable thermal paper:

  • Keeps print legible for years
  • Resists fading, moisture, and heat
  • Is ideal for industries like retail, hospitality, banking, and fuel stations
  • Reduces the need for reprints and customer complaints

Key Testing Methods to Evaluate Durability

1. Heat Resistance Test

Exposing paper to high temperatures (e.g. 60°C) checks if the image fades. Quality thermal paper like MilaMima 3 1/8" x 225' Rolls remains readable after heat exposure.

2. Light Exposure Test

Receipts placed under direct light for days or weeks will reveal how long the print lasts. Fading indicates low-quality coatings.

3. Moisture Test

Spray or expose thermal paper to humidity. Good thermal paper resists curling, blotching, or smearing.

4. Abrasion Test

Rub the surface with a finger or cloth. If the print smudges easily, the coating isn’t durable enough for long-term usage.

What to Look For When Buying Durable Thermal Paper

  • BPA-Free & BPS-Free: Safer and environmentally friendly.
  • Coated for Longevity: Look for multi-layer coatings designed for extended life.
  • Proper Storage Specs: Rolls that are tested to endure light, heat, and time.
  • Compatibility & Size: Ensure fit for your POS, printer, or terminal.
