How to Store Thermal Rolls to Maintain Print Quality

About MilaMima
As a trusted Canadian brand, MilaMima specializes in premium thermal paper rolls, POS supplies, and office paper that help businesses keep their operations running smoothly. Our BPA-free thermal rolls deliver crisp, durable prints — but to ensure long-lasting quality, proper storage is just as important as choosing the right product.

Why Storage Conditions Matter

Thermal paper relies on a heat-sensitive coating to create images and text. While durable, this coating can degrade when exposed to excessive heat, light, or humidity — leading to faded receipts, jammed printers, or poor print quality. With the right storage practices, you can extend the lifespan of your paper rolls and maintain clear printing results every time.

Best Practices for Thermal Paper Storage

• Keep Away from Heat Sources: Store rolls at room temperature, ideally between 15°C and 25°C (59°F–77°F). Avoid keeping them near heaters, ovens, or direct sunlight.
• Control Humidity: Maintain a relative humidity level between 45% and 65%. Excessive moisture can cause the paper to curl or stick, while overly dry air may lead to brittleness.
• Protect from Light Exposure: Prolonged exposure to fluorescent or UV light can fade the thermal coating. Keep rolls in their original packaging or a closed container until use.
• Avoid Chemical Contact: Substances like cleaning agents, solvents, or plasticizers from vinyl surfaces can react with the coating. Always store rolls away from chemicals or PVC materials.
• Store Upright and Flat: Stack rolls flat and avoid heavy pressure that can deform their shape. For long-term storage, keep them in a clean, dry cabinet or drawer.
• Use FIFO (First In, First Out): Rotate your stock so older rolls are used first. Even with proper storage, thermal coatings can slowly degrade over time.

Signs of Poor Storage

If your printed receipts appear light, streaked, or uneven, the paper may have been exposed to heat or moisture. In severe cases, the coating might turn gray before printing — a sign the rolls are expired or improperly stored. Replacing them with fresh, well-preserved rolls will restore printing performance and prevent unnecessary printer wear.

How MilaMima Rolls Stay Reliable

Our MilaMima thermal rolls are produced with durable, high-sensitivity coatings and packed in moisture-resistant wrapping to protect them from environmental factors during shipping and storage.

In Summary

Proper storage of thermal paper rolls directly affects print quality, durability, and printer lifespan. Keep your rolls in a cool, dry, and dark place, and always handle them with care. Combined with MilaMima’s BPA-free, high-performance paper, these simple steps guarantee dependable printing for your POS or receipt systems all year round.
