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 recyclable 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.
- PET or PETE: Polyethylene Terephthalate - PET is commonly used for soft drink & water bottles, cooking oil bottles, peanut butter containers. It is the most widely recycled plastic.
- HDPE: High-Density Polyethylene - Identifies milk, cider & water jugs, detergent, fabric softener & bleach bottles. HDPE is slightly waxy and semi-rigid. It does not crack. It floats in water.
- PVC: Polyvinyl Chloride - Also abbreviated V, PVC is used in salad dressing bottles, vegetable oil bottles and mouthwash bottles. PVC is smooth, scratches easily and sinks in water.
- LDPE: Low-Density Polyethylene - LDPE is used in flexible bags for dry cleaning, trash, produce, bread and shrink wrap. Recycled LDPE is often used to make grocery bags.
- PP: Polypropylene - PP is usually is found in drinking straws, battery cases, some dairy tubs, bottles labels and caps, and rope. PP stretches into filaments and emits a chemical smell when burned.
- PS: Polystyrene - PS and Expanded Polystyrene (EPS) both are No. 6 plastics. PS and EPS are commonly used in packaging peanuts and other packaging materials and in plastic utensils, mean and egg trays. PS sinks in water; EPS floats.
- Other - Other plastics often are made of multiple resins or layers of different types of plastics. These may include microwave packages, snack bags and industrial plastics.
