Thermal paper is commonly used to print receipts, and some studies are emerging to suggest that prolonged contact to such paper may be harmful.
WORDS LIM TECK CHOON
FIRST, A LITTLE BACK STORY
Once upon a time, bisphenol A (BPA for short) was a substance used widely in the manufacture of polycarbonate plastic products. Almost every plastic product and even water supply pipes had BPA.
People became concerned when studies conducted on animals found that BPA could cause negative effects on foetuses and newborns.
Hence, BPA was eventually phased out of use, to be replaced by similar compounds such as bisphenol S or BPS.
BPS MAY BE PROBLEMATIC TOO?
Because BPS has the same structure and chemical properties as BPA, researchers have researched more and more into this compound.
Results are so far mixed, but there are indications that BSA that found its way into foods and drinks may be as toxic as or even more toxic than BPA.
Hence, more and more investigators are calling for worldwide authorities place BSA under the same legal restrictions as BPA.
THE LINK TO RECEIPTS
Thermal paper, the most common type of paper used to print receipts on, contain BSA.
Therefore, opting for paperless receipts is always a good idea. It’s good for the environment—and potentially for our health too!
If You Are Concerned About Touching Paper Receipts, Here Are Some Tips
- Choose paperless or digital receipts if the option is available.
- Hold the paper receipt lightly with as few fingers as possible. Avoid crumpling or touching it unnecessarily.
- Wash hands thoroughly after touching the paper receipt, especially before preparing foods or eating.
- Keep the paper receipt dry. Avoid touching it with wet or greasy hands.
- Don’t place the paper receipt in contact directly with foods, such as inside a shopping bag containing fruits and vegetables without plastic packaging.
