Thermal Paper is a versatile media that can be used for receipts, invoices, tickets, labels and printed material. However, the limited shelf life creates special requirements for the storage and achievability of thermal rolls. Here you will find valuable tips on the durability of thermal paper and an explanation of the advantages of thermal paper without bisphenol.
What you should consider when storing thermal paper
If you are using a thermal printer, it is important to store unprinted thermal rolls and receipt paper properly. Avoid exposure to ultraviolet rays and heat, such as from a radiator or direct sunlight. Provide suitable environmental conditions so as not to impair printability or typefaces. Previously improperly stored paper can even shorten the life of thermal printers if the print head is rubbed or debris caused by curled or damaged paper. Therefore, please note the following tips on thermal paper shelf life:
- Store thermal paper in a cool and dry place.
- Avoid exposure to light and heat.
- Before being ready to use, you must put the thermal roll in its original packaging for better protection.
- Avoid damage to the roller from scratches, collisions, or deformation.
- Keep the storage period short.
If stored properly, thermal paper can be stored for at least 5 years.
The advantages of thermal paper without bisphenol
Bisphenol A (abbreviated as BPA) is a chemical compound that can be used as a color developer in thermal paper. An EU regulation prescribes thermal paper without bisphenol A for receipt paper from 2020 due to health effects that have not been conclusively clarified. However, this is not a disadvantage for you because the typeface and printability of the BPA-free thermal rolls are perfect. In terms of the durability of thermal paper, phenol-free thermal paper rolls are convincing compared to other papers with a longer archival time of 5 to 7 years, depending on the storage time. Thermal rolls that do not contain bisphenol can also be stored for up to 10 years. Thermal paper that does not contain bisphenol A can provide you with a high degree of whiteness, uniform blackness, high resistance to environmental impacts, and possible disposal in waste paper recycling.
Correct archiving of thermal paper receipts
The obligation to store receipts and receipts presents you with the challenge of the achievability of thermal printing. This is because the retention period during the prints remain legible depends largely on the environmental impacts and environmental conditions. These may fade or ruin the typeface. In principle, you can archive thermal paper receipts for several years if you follow the instructions below:
- Avoid strong heat and direct sunlight to prevent the thermal paper from fading.
- Oils, fats, chemicals and tannins will attack receipt paper and make it difficult to read.
- Wrinkles and abrasion also affect the typeface.
For long-term storage, plastic or paper sleeves without plasticizers are suitable for protection. For maximum archival capacity, an ambient temperature of around 20 ° C and relative humidity of 40% to 60% is ideal.
The future of the thermal paper medium
Thermal Paper is an unstable medium and is therefore increasingly affected by environmental influences. Thermal printers currently do not produce “document proof” typeface. Basically, the technology and printability of thermal rolls have been significantly improved since the first fax papers were introduced. The industry is committed to further improving the durability of thermal paper, for example, through new surfaces and printing processes.
Special thermal papers already promise a lifespan of up to 25 years. However, this only applies to the appropriate environmental conditions and is generally not provided. Therefore, as before, you need to pay attention to the correct storage.
The immediate future of thermal paper depends on phenol-free and environmentally friendly thermal rolls as receipt paper and without a chemical color developer. Due to the increasing popularity of cashless payments, the future of receipts may seem digital, but until then, you have to use paper receipts due to retention requirements.
