What about Formaldehyde?
Many questions have been asked about the existence of formaldehyde in Acetal Copolymer. While it is true formaldehyde is present in trace amounts, research proves it is only released at very high temperatures, well above any temperatures found in home food canning. Here are the facts.
Heating our brand of acetal copolymer above 460 degrees F (238 C) should be avoided. At these temperatures, formaldehyde, a colorless and irritating gas that can be harmful in high concentrations, is generated.
What about the Recycle Symbol on the Lids?
Numerous inquiries have been made regarding the Number 7 recycling symbol found on Tattler Reusable Canning Lids. Many people believe the presence of this symbol contradicts the claim that our product is BPA Free, and all products contained within this category leach toxic chemicals. Both of these beliefs are incorrect.
There are 7 classifications of recycleable materials, the last of which Tattler Reusable Canning Lids fall within due to its "Other" classification. Each of the previous 6 categories is very specific as shown in the following definitions listing. The Number 7 category includes all "other" products that do not fall into the previous 6 specific categories. Plastics which contain BPA do fall into Class 7, but the presence of the symbol DOES NOT automatically mean that all products in the category contain BPA.
