Sheet material polymer science has made a classic bell curve of major categories. Some clearly defined groups are shown below.
There are components of each that are known to leach during heating or cleaning etc. Many are labeled " do not put in dishwasher"
Select safer plastics that contain polyethylene, (#1 ,#2, and #4) and polypropelene (#5) which requires less use of toxic additives. They also are non-chlorinated.



Avoid using products that use polyvinyl chloride (#3) polystyrene (#6), and polycarbonate (#7) All three are sometimes found in plastic baby bottles and sippy cups.



It is well known as that migration levels of BPA increases (bisphenol A) with increasing temperature. Pacifiers, and teething toys sometimes contain BPA but the heating processes and toxin exposure is slightly less.
