A significant percentage of thermal papers on the worldwide market use technology that employs the chemical bisphenol A, or BPA. These types of papers are known for their reliability and durability, as well as for their safety.
What is Bisphenol A?
Bisphenol A is an important chemical building block used in a wide variety of applications since the 1950s. BPA has many properties that make it extremely useful for the manufacture of high-performance products, including the strong and shatter-resistant plastic known as polycarbonate, and epoxy resins used to make protective coatings that, among other uses, preserve the safety and integrity of canned foods and beverages by preventing corrosion and contamination.
Why is BPA used in thermal paper?
Because BPA is extremely stable and heat-resistant, it is used to make the coatings that give thermal paper the unique properties that allow for inkless printing. BPA is also one of the most widely researched substances on the market, and has been used extensively in commerce for 50 years with no evidence of harm to human health – even among workers exposed to significantly higher levels than the general public.
Extensive data on BPA exists from more than a thousand studies examining a number of its properties, including toxicity, ecotoxicity, metabolism, pharmacokinetics and human exposure.
