BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. Throughout that time it has had many uses. Especially for containers that store food and beverages including water bottles, baby bottles, food containers and epoxy linings for metal-based food and beverage cans.
On this post, we will bring clarity on the history and current safety status of BPA plastics and will discuss the following topics:
BPA stands for Bisphenol A. It is an organic synthetic compound that is used to manufacture plastics containing polycarbonate, like food and drink containers. BPA is also found in epoxy resins that can be found as liners in metal products like food cans, bottle tops, and water supply pipes.
While it was first discovered and first synthesized by Russian chemist Aleksandr Dianin in 1891, it wasn’t used in the manufacturing process of Polycarbonate (PC) until the 1950s. Before its use in plastics, Edward Charles Dodd identified that BPA had estrogenic properties when looking for a drug for estrogen in the 1930s. This led to the discovery of diethylstilbestrol (DES) but was later banned in 1971 after it was discovered to be carcinogenic. It took several decades until it was first synthesized in the first epoxy resins by chemists at the companies of DeTrey Freres in Switzerland and DeVoe Raynolds in the US. This later resulted in the first uses of BPA in plastics in the early 1950s, thanks to further discoveries at Bayer and General Electric.
The polycarbonate resin resulting from the use of BPA in the manufacturing of plastics was initially used for electrical and electronic applications. Over time, it became popular for other uses such as plastic bottles, lining for metal-based food and beverage cans and other containers for consumer goods.
Most people living in the US have been exposed to BPA in some way. Although there have been some efforts to reduce its use in packaging materials and promote BPA-free alternatives, BPA can be found in many household items. Some of the most common items that tend to contain BPA include:
If you are reading this and would like to know how to determine if household consumables and containers are BPA-free, there are a couple of ways to identify them.
You can easily determine what plastics are BPA-Free by looking at the number stamped on the product. There are different types of plastic containers that are labeled with a 1, 2, or 5 are considered BPA-Free. Plastic products stamped with a 7 indicate a possibility that BPA was used to make the product.
1. Check the recycling number at the bottom of the container:
2. Check if the plastic is soft and pliable. Note that plastics containing BPA are usually translucent and hard, such as in water or baby bottles.
3. How old is the plastic product? Make sure to mention that if a product has been in use since the late 1950s, there is a possibility that it contains BPA and is less likely to have an identifying label.
Now that you understand the history and can identify plastic containers that are BPA free you may be wondering where you can find safe BPA free plastic for your product. All Packaging Options Direct’s plastic bottles and jars are BPA free and safe to use on foods, beverages, and other consumer products.
Safety is one of the biggest concerns because exposure to BPA for most people happens through what they eat. According to the National Institute of Environmental Health Sciences, BPA can be transferred to your food or drink with heat. To be more specific, the protective internal epoxy resin coatings of consumer products like tableware, food storage containers, and water bottles can be transferred over whenever they are reheated. The applied heat essentially breaks down the plastic over time, allowing BPA to be transferred onto food and drinks.
Some symptoms and side effects of being exposed to BPA consist of the following:
To summarize, BPA has a long-storied history over the last 100 years. Over time we have learned that BPA can be harmful to humans for a variety of reasons. We have also given you the ability to identify if your product or container contains BPA. The good news that is BPA has been phased out of almost all plastic manufacturing and is much harder to encounter today.
Always know that Packaging Options Direct’s selection of plastic bottles, jars, and accessories are 100% BPA free. If you have questions about a particular product on its safety or viability for your next product or product, please don’t hesitate to reach out. We are always happy to help!
