Why Do Paper Receipts Fade Over Time?
What It Is
Paper receipts often fade until the printed text becomes hard to read or disappears completely.
How It Works
Most receipts are printed on thermal paper, which does not use traditional ink.
Instead, heat activates a chemical coating on the paper to create the printed text.
Why It Happens
- Thermal paper reacts to heat and light
- Chemical coatings break down over time
- Sunlight speeds up fading
- Heat from wallets or pockets affects the paper
Common Examples
- Receipts fading in a wallet
- Text disappearing after months in storage
- Receipts turning dark or blank
What to Know Next
Storing receipts away from heat and light can slow fading but will not stop it completely.
Simple Caution
Thermal receipts are not designed for long-term record keeping.
Closing Summary
Paper receipts fade because thermal paper uses heat-sensitive chemicals that break down over time.
