We use high temperature paper (170F, 20% dark at 6mJ/mm²). It will not turn dark left many days in a truck dashboard in the summer in Texas.
I once found a stack of 7 year old receipts and they were completely readable.
Worth looking at Figure 3 showing how different samples of thermal paper have vastly difference reactions to high temperatures.
Once had a set of Aliexpress plastic water carriers take 6 months to arrive to me during COVID and it when it arrived, it seemed like the plasticizers from the carriers (or the factory?) severely degraded the thermal shipping label.
