Thermal receipt paper plays a critical role in ensuring accurate, fast, and clear printouts at the point of sale. But what exactly makes thermal paper work, and why does material quality matter? In this article, we break down the science behind thermal printing and explain what makes MilaMima’s 2 1/4" x 60'/50'/30' BPA-free thermal paper rolls stand out.
How Thermal Printing Works
Thermal printers do not use ink, toner, or ribbons. Instead, they rely on a heat-sensitive coating applied to thermal paper. When the paper passes over a heated thermal printhead, the coated surface reacts by turning black in specific areas, forming text or images. This process is known as direct thermal printing.
Key benefits of this technology:
- Quiet and fast operation
- No need for ink cartridges
- Compact design, ideal for POS systems
What Is Thermal Paper Made Of?
Thermal paper is typically composed of three layers:
- Base layer: High-quality paper material that provides durability and structure.
- Undercoating: Ensures smooth printing and protects the heat-sensitive layer.
- Thermosensitive coating: Reacts to heat and creates visible prints without ink.
MilaMima uses premium-grade paper with a 68 GSM (grams per square meter) rating, offering better thickness, smoothness, and resistance to tearing compared to low-cost alternatives.
BPA-Free and Eco-Conscious
Bisphenol A (BPA) was once commonly used in thermal coatings but has since raised health and environmental concerns. MilaMima thermal paper is 100% BPA-free, ensuring that your business stays compliant with modern safety standards while providing peace of mind to both staff and customers.
