What plastic bottles are BPA free?
Bisphenol A (BPA) is a chemical that has been used to make certain plastics and resins since the 1960s. It can be found in polycarbonate plastics and epoxy resins, which are often used in food and drink packaging such as plastic bottles and the lining of metal cans. There has been concern about the potential health effects of BPA, as it can mimic the hormone estrogen once ingested. This has led many consumers to seek out BPA-free plastic bottles, especially for items like water, juice, and baby bottles.
What is BPA?
BPA, or bisphenol A, is an industrial chemical used to make certain plastics and resins. Polycarbonate plastics contain BPA – these are rigid, clear plastics used to make reusable bottles, food storage containers, eyeglass lenses, CDs, and more. Epoxy resins containing BPA are used as coatings on the inside of many food and drink cans and as dental sealants.
BPA is classified as an endocrine disruptor, meaning it can mimic or interfere with natural hormones in the body, specifically the female sex hormone estrogen. When BPA leeches from containers into food and beverages, it can then be ingested. Once in the body, it may interfere with natural hormone signaling, especially during vulnerable periods of early development. There is ongoing scientific evidence looking at the possible health effects of BPA.
Why choose BPA-free bottles?
There are a few key reasons why many consumers choose BPA-free plastic bottles, especially for water, baby bottles, and other beverages:
- Reduce exposure to hormone-disrupting BPA – Choosing BPA-free bottles reduces the risk of ingesting the chemical.
- Prevent leaching into contents – BPA can leach from containers into foods and liquids they contain, especially when heated.
- Limit risk during early development – Infants and young children may be especially vulnerable to effects.
- Avoid possible health effects – Research indicates BPA may impact growth, metabolism, reproduction, neurological function, and more.
Major health and regulatory agencies advise avoiding BPA exposure during pregnancy and early childhood as much as possible. Using BPA-free plastic bottles is an easy way to lower this exposure from beverage containers.
Types of Plastic and BPA
Not all plastics contain BPA. Here is an overview of some different types of plastic and whether they contain BPA:
- Polycarbonate (PC): These rigid, clear plastics are a major source of BPA exposure since the chemical is used in their manufacturing process. Reusable drink bottles, food containers, lenses, and CDs/DVDs are often made of polycarbonate plastic.
- Polyethylene Terephthalate (PET or PETE): PET plastic is commonly used for disposable water, soda, and salad dressing bottles, as well as some reusable drink bottles. It does not contain BPA.
- High Density Polyethylene (HDPE): HDPE plastic is used for opaque plastic bottles of milk, juice, and cleaning products. It is also used for some reusable bottles and does not contain BPA.
- Low Density Polyethylene (LDPE): LDPE plastic includes plastic wraps, bags, food containers, and flexible bottle lids. It does not contain BPA.
- Polypropylene (PP): This plastic type is used for yogurt cups, squeeze bottles, straws, clothing, and reusable bottles/food containers. Polypropylene does not contain BPA.
- Polystyrene (PS): Polystyrene plastic is used for styrofoam cups and take-out containers. It may leach other hormone disruptors but does not contain BPA.
This overview shows that polyethylene (PET, HDPE), polypropylene (PP), and low density polyethylene (LDPE) plastics provide BPA-free options for plastic bottles and food containers.
