What is BPA?
Bisphenol A (BPA) is an industrial chemical used in the manufacture of plastics. It is used primarily because it lends the material strength and toughness, as well as making it near shatter-proof. One of the main types of plastic it is used in is polycarbonate, which is robust, possesses great optical clarity, and is very lightweight.

BPA was first discovered in 1891 and has grown to be one of the most widely produced chemicals in the world. According to a University of Missouri review, 2011 saw the production of over 4.5 million tonnes of BPA plastic globally.
Due to its presence in so many products, the chemical is passed into our bodies, most often from food and drink consumed from containers made with BPA. The Centre for Disease Control found that 93% of people tested had the substance present in their system.
Should I be worried about BPA?
BPA can act as a synthetic oestrogen, the female reproductive hormone. Theories suggest BPA can trick the body and cause an imbalance in our systems, leading some studies to link the substance with health risks for pregnant women and infants.
At the time of writing, the consensus is that at the current levels found in humans, no harmful effect is evident. This is a stance adopted by the European Food Standards Agency (EFSA), indicating that levels are considerably below the tolerable daily intake.
Where did the concern around BPA come from?
Recent concerns were raised in 2008 when it was found that every infant formula manufacturer used BPA in their containers. Because of the uncertainty over the effects on infants, many manufacturers began switching to a BPA-free production process to allay public fears.
What are BPA-free products?
BPA-free products are manufactured without the chemical, replacing it with alternatives not associated with health risks. Many manufacturers now offer water bottles, baby cups, and food containers in BPA-free plastic.
How can I tell if a product is BPA-free?
Check the manufacturer description or look for a BPA-free sticker. The most reliable way is to check the plastic identification code number stamped on the bottom of the container.
Categories 1 to 6 are typically free of BPA. Number 7 may contain the chemical. The two most common and safest BPA-free plastics are categories 2 and 5.
| Number | Code | Name of Plastic | Examples |
|---|---|---|---|
| 1 | PETE / PET | Polyethylene terephthalate | Soft drinks bottles |
| 2 | HDPE | High-density polyethylene | Food storage containers |
| 3 | V / PVC | Polyvinyl chloride | Debit and credit cards |
| 4 | LDPE | Low-density polyethylene | Plastic shopping bags |
| 5 | PP | Polypropylene | Reusable food storage |
| 6 | PS | Polystyrene | Foam drinking cups |
| 7 | OTHER | Other (may include BPA) | Miscellaneous items |
Do I need to buy BPA-free products?
There is no hard evidence to suggest normal exposure is harmful. However, if you are concerned, BPA-free products allow you to use everyday items with peace of mind. There are plenty of great alternatives available at Plastic Box Shop.
Are there any other ways of minimising exposure to BPA?

- Avoid canned food: Can linings often contain BPA. Choose fresh or frozen varieties instead.
- Avoid microwaveable meals: Packaging can transfer chemicals to the food when heated.
- Avoid microwaving polycarbonate: Material can break down and release BPA. Check for the number 7 code and avoid heating those containers.
- Buy wooden gifts: Consider traditional wooden toys for children instead of plastic.
- Use traditional tableware: Opt for metal cutlery and ceramic plates rather than plastic versions.
