Bisphenol A (BPA) is a chemical frequently used in plastics, coatings, and resins. Its presence in plastics is a concern due to its potential negative effects on health. BPA exposure may affect the brain, the prostate gland of fetuses, infants, and children, and it might increase blood pressure. It is therefore important to know whether a plastic product is BPA-free. One way to identify this is by looking at the recycling codes on plastic products. Type 5 plastic, also known as polypropylene, is generally considered BPA-free. It is a safer alternative to other types of plastics and is FDA-approved for food contact.

What You'll Learn
Polypropylene is considered safe
Polypropylene, a plastic derived from petroleum, is considered a safer alternative to other types of plastics. It is FDA-approved for food contact and is used in containers for products like yoghurt, cream cheese, and butter. It is also used in packaging materials, bottles, beverage cups, and food trays. It is marked with the number 5 surrounded by a triangle at the bottom.
Polypropylene is also known for its high performance and high-temperature performance. It is chemically resistant and has good impact strength. It is considered a low-toxin material and is resistant to bacteria. It is also inexpensive and strong, making it ideal for various applications.
However, some newer research has pointed to potential toxicity in certain polypropylene containers. A 2019 study found that some polypropylene products affected androgen hormones and caused a toxic or stress response in cells. This has led to concerns about the potential health risks of using polypropylene, especially since it is used in many products that come into contact with food and humans. Nonetheless, the FDA and EPA have not changed their recommendations for the use of polypropylene, and it is still considered one of the safer plastic options available.

FDA-approved for food contact
Polypropylene, a complex plastic, is generally considered safe for humans. It is FDA-approved for food contact and is often used for containers like those that hold yoghurt, cream cheese, and butter products. Polypropylene is derived from petroleum and is considered by the Environmental Protection Agency (EPA) to be a safer choice than some other types of plastics. It is not known to cause cancer in humans and is less flammable than wool.
Polypropylene is marked with a number 5 surrounded by a triangle on the bottom of the container. It is important to note that while polypropylene is considered safe, the manufacturing process for plastic products may not be environmentally friendly. Additionally, some newer research has pointed to toxicity in certain polypropylene containers, specifically affecting androgen hormones and causing a toxic or stress response in cells. However, this research has not changed the FDA's or EPA's recommendations for the use of polypropylene.
The FDA has strict regulations for substances that come into contact with food. The FDA maintains an inventory of Food Contact Substances (FCS) that are authorised for use with food. This inventory includes information on the specific intended uses and use conditions authorised for each substance. The FDA also provides guidelines for determining the regulatory status of substances used in food contact applications.
To ensure that a plastic product is BPA-free, you can look for recycling codes or resin identification numbers, usually printed on the backside of plastic items. Polypropylene, with the recycling code "5", is typically BPA-free. However, it is always good to check the labels or packaging of products for any statements regarding BPA presence.

No known cancer-causing effects
Polypropylene, a complex plastic, is generally considered safe for humans. It is FDA-approved for food contact and is widely used for containers like those that hold yoghurt, butter, and cream cheese products. It is denoted by the number 5 surrounded by a triangle on the bottom of the container.
Polypropylene is known to be a safer alternative to some other types of plastic. It is considered by the Environmental Protection Agency (EPA) to be a safer choice than some other types of plastics. It is not known to cause cancer in humans and is less flammable than wool. The FDA has approved its use as a food container material, and there are no known cancer-causing effects associated with polypropylene.
However, it is important to note that some newer research does point to toxicity in certain polypropylene containers. Researchers in a 2019 study found that the toxicity of a particular plastic varied dramatically from product to product due to each product's manufacturing process. In this study, it was found that some polypropylene products affected androgen hormones and caused a toxic or stress response in cells. More research is needed, especially since plastics are chemically complex, and each product could have different effects.
Despite this new research, the FDA and EPA have not changed their recommendations for the use of polypropylene. It is still considered one of the safer plastics on the market and is widely used in food storage containers.
To summarise, while polypropylene (or type 5 plastic) is generally considered safe and is not known to cause cancer, some newer research has raised concerns about the toxicity of certain polypropylene products. More studies are needed to confirm these findings and determine the specific effects of different polypropylene products. In the meantime, individuals can promote environmental consciousness and well-being by adopting BPA-free, healthier lifestyle choices by using recycling codes as a guide.

Identifying BPA-free plastics
Bisphenol A (BPA) is a chemical compound used to manufacture plastics containing polycarbonate, commonly used in food and drink containers. It 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 the FDA has indicated in the past that BPA is not shown to be particularly harmful in food and beverage packaging, many consumers want to avoid it. Some manufacturers boldly state "BPA-free" on their products, but if you want to be sure, here are some ways to identify if a plastic product is BPA-free:
- Check the labels or packaging of products for any statement about BPA presence.
- Check the recycling codes, often called resin identification numbers, usually printed on the backside of plastic items. Each number corresponds to a specific plastic type and provides information about the material content and, in some cases, the presence of BPA.
- Look for plastics with recycling codes 1 (PET), 2 (HDPE), 4 (LDPE), and 5 (PP). These plastics are generally considered safe and are known for their high performance and high-temperature tolerance.
- Use Code 3 (PVC) products with caution as they may contain BPA.
- Code 6 (PS) is generally safe, but excessive heat can cause problems as harmful chemicals will be released.
- Code 7 is a "catch-all" category, and it is difficult to determine whether these plastics contain BPA.
Polypropylene, or PP, is the plastic type with recycling code 5 and is considered one of the safer plastics. It is FDA-approved for food contact and is often used for containers like those that hold yogurt, cream cheese, and butter products. It is considered to have no known cancer-causing effects, although newer research points to toxicity in certain polypropylene containers.

Recycling codes and safety
Plastic products are labelled with a number inside a recycling symbol, typically on the bottom, side, or top. These recycling codes, often called resin identification numbers, are important for determining whether a plastic product is BPA-free. BPA, or Bisphenol A, is a highly toxic chemical found in plastic that is linked to obesity, cancer, and endocrine problems in fetuses and children.
Polypropylene, or PP, is the plastic with recycling code 5. It is considered one of the safer plastics and is FDA-approved for food contact. It is generally considered safe for humans and is not known to have any cancer-causing effects. However, some newer research points to toxicity in certain polypropylene containers, with researchers finding that some polypropylene products affected androgen hormones and caused a toxic or stress response in cells. Nevertheless, this research has not changed the FDA's or EPA's recommendations for the use of polypropylene.
Recycling codes 1 (PET), 2 (HDPE), 4 (LDPE), and 5 (PP) are generally considered BPA-free. Code 3 (PVC) products may contain BPA and should be used with caution, while Code 6 (PS) is generally safe but can cause problems when exposed to excessive heat. Code 7 (OTHER) is difficult to recycle and may contain BPA, so it is best to stay away from this type of plastic.
To ensure optimal safety when using plastic products, it is important to follow certain guidelines. For example, it is recommended to avoid exposing BPA-free plastics to high temperatures, as temperature affects their stability. It is also important to store BPA-free containers away from direct sunlight and heat sources. Additionally, it is advisable to replace plastic containers showing signs of wear or discolouration, especially those used frequently or with hot foods, as the material can degrade over time.
