In November Appleton, North America’s largest producer of direct thermal media announced the addition of easy-to-see red fibers to its most common POS receipt paper grade “Alpha 400-2.1”.
At this time, offshore supplier Koehler also has BPA-free receipt paper; their grade "KT48FA". Koehler is a large supplier of thermal paper to the US. This simply means that your thermal receipt paper may be BPA-Free even if it doesn't have red fibers.
If you purchase thermal receipt paper and are concerned about the effects of BPA, ask your supplier about the BPA-free options available to you. You can visit http://www.possupply.com/BPA-Free-Thermal-Paper-Rolls for a complete list of the products that we offer.
