You know those little triangle symbols on the bottom of your plastic containers? They’re not just for show.
Each number within the triangle corresponds to a different type of plastic. Plastics labeled with a ¡°7¡± often contain BPA. However, not all plastics labeled ¡°7¡± contain BPA, so it’s important not to make assumptions based solely on this number.
Here’s a table covering the recycles codes of plastic and whether they’re BPA free¡
| Recycle Code | Common Name | BPA Free? | Can be Reused? | Common Uses |
|---|---|---|---|---|
| 1 | PET or PETE | Yes | Not recommended for reuse due to the risk of bacterial growth | Water and soft drink bottles, salad domes, fruit containers |
| 2 | HDPE | Yes | Yes, can be reused | Milk jugs, detergent bottles, grocery bags, yogurt tubs |
| 3 | PVC or V | Yes | Not recommended for reuse due to potential leaching of phthalates | Piping, siding, blister packs, wire jacketing |
| 4 | LDPE | Yes | Yes, can be reused | Bread bags, frozen food bags, squeezable bottles |
| 5 | PP | Yes | Yes, can be reused | Bottle caps, food containers, straws |
| 6 | PS | Yes | Not recommended for reuse due to potential leaching of styrene | Disposable plates and cups, meat trays, egg cartons, carry-out containers |
| 7 | Other | Often, but not always. This category can include polycarbonate, which contains BPA | Depends on the specific type of plastic | Baby bottles, some reusable water bottles, some metal can linings |
Secondly, many manufacturers now label their products as ¡°BPA-free¡± if they do not contain the chemical.
If you see this label, it’s a good indication that the product is BPA-free. But, just like the recycling codes, this isn’t foolproof. Some manufacturers may use BPA substitutes that could also have potential health effects.
And, when in doubt, do your research.
Many manufacturers now have information about their use of BPA available on their websites. And if you can’t find the information you’re looking for, don’t be afraid to reach out to the manufacturer directly. They should be able to provide you with the information you need.
For instance, this is Eastman.com, a well-known plastic company, explicitly making note that their plastics are BPA-free¡
Tips to Avoid or Reduce BPA Exposure
Obviously, BPA is not an exciting thing to hear, especially if you’re like most people ¡ª who use plastic for basically everything. But then, how can you avoid the effect or exposure of BPA?
Switch to other alternatives
One of the simplest things you can do is to switch from plastic to glass or stainless steel for food and drink storage. Not only do these materials not contain BPA, but they’re also durable and reusable, which is a win for the environment too.
Avoid using Plastic Heat
Remember how we discussed that heat can cause BPA to leach out of plastic? Well, that gives us a clear action point: avoid microwaving food in plastic containers. Instead, transfer your food to a ceramic or glass dish before warming it up.
Now, there might be some plastics that are good with heating, but they’re better avoided, especially when you’re in dire need to avoid BPA exposure.
Avoid Canned Foods
When it comes to canned goods, try to opt for fresh or frozen alternatives when possible. If you do buy canned foods, look for brands that advertise a BPA-free lining.
Lastly, wash your hands after handling receipts, especially before eating or preparing food. Receipts are a less-known source of BPA, but they can contribute to your overall exposure.
Final Thoughts
To mitigate the leaching of BPA, it is essential to explore alternative materials and manufacturing processes that eliminate or reduce the presence of BPA in plastic products.
Additionally, proper storage and handling practices, including avoiding exposure to high temperatures and acidic environments, can help minimize the release of BPA into our surroundings
