Bisphenol A (BPA) is a chemical used to harden plastics and make them shatterproof. It can be harmful to human health, especially for children and pregnant women. To identify if a plastic product contains BPA, you can look for a BPA-free label or check the recycling codes, often called resin identification numbers. These recycling triangles are usually printed on the backside of plastic items, with numbers ranging from 1 to 7. Code 1 plastic, or polyethylene terephthalate (PET), is generally considered to be BPA-free. However, while it is safer than other plastics, it still poses potential health and environmental risks.

Plastic #1 isn’t too terrible, but needs to be stored in cool environments and should not be reused
Plastic #1, or PET, is polyethylene terephthalate, a plastic resin that is BPA-free and safe. It is widely used in the production of textiles, beverage bottles, and food containers. It is easily recyclable and has a low potential for chemical leaching. However, it should not be reused, especially for storing food and drinks, as it can harbour bacteria and break down over time. This is why plastic #1 containers are intended as single-use, and you should not refill plastic water bottles labelled with resin recycling code 1.
While plastic #1 is considered relatively safe among plastics, it should be stored in cool environments. This is because heat increases the chances that chemicals will seep out of the container and into your food or drink. Therefore, it is not suitable for storing hot liquids or heating food. Even if a plastic is labelled "microwave-safe", it is better to be cautious and avoid microwaving plastic #1.
Bisphenol A (BPA) is a chemical used to harden plastics and make them shatterproof. It can disrupt hormones and pose risks to children and pregnant women, and is linked to obesity, cancer, and endocrine problems in fetuses and children. Therefore, it is important to avoid plastics that contain BPA.
To identify if a plastic product contains BPA, you can look at the recycling codes, often called resin identification numbers. These recycling triangles are usually printed on the backside of plastic items and contain ID numbers corresponding to specific plastic types. Plastic #1 is one of the safer options, along with codes #2, #4, and #5. Codes #3, #6, and #7 should be approached with more caution as they may contain BPA.
While plastic #1 is convenient and widely used, it is still recommended to prioritise reusable and environmentally friendly materials such as glass, metal, or bamboo whenever possible.

Polyethylene terephthalate (PET) is a BPA-free plastic with low potential for chemical leaching
Polyethylene terephthalate (PET) is a type of plastic resin that is commonly used in the production of textiles, beverage bottles, and food containers. It is identified by the recycling code "1" and is known to be BPA-free.
BPA, or Bisphenol A, is a chemical commonly used in the production of polycarbonate polymer and epoxy resins. While it is not inherently harmful, there have been concerns raised about its potential health effects, particularly when it leaches into food and beverages. As a result, many manufacturers have started to produce ""BPA-free" products, using alternative materials like PET.
PET plastic is considered to have a low potential for chemical leaching. However, studies have shown that PET plastics can leach a toxic heavy metal called antimony. Antimony is used as a catalyst in the production of PET plastic, and while it is not inherently harmful, chronic exposure to high levels of antimony can lead to serious health issues.
The leaching of antimony from PET plastic has been observed in bottled drinking water, with higher concentrations found in regions with high consumption of bottled water and elevated temperatures. Additionally, PET plastic can also leach phthalates, which are added to increase flexibility, transparency, durability, and longevity. Both antimony and phthalates can be released into the environment and ingested orally, inhaled, or absorbed through the skin.
To minimize the potential for chemical leaching from PET plastic, it is recommended to avoid using plastic food and beverage packaging, opting for glass instead. Reducing exposure to high heat and long storage times can also help decrease the leaching of chemicals.

Recycling codes: Code 1 plastics are generally considered safe and BPA-free
Plastic recycling codes, often called resin identification numbers, are usually printed on the backside of plastic items. Each code corresponds to a specific plastic type and provides information about the material content and, in some cases, the presence of Bisphenol A (BPA). The numbers 1-7, created by the Society of Plastics Industry (SPI) in 1988, help identify and sort various plastics for recycling.
Code 1 plastics are made from polyethylene terephthalate (PET), which is BPA-free and safe. PET is widely used in the production of textiles, beverage bottles, and food containers. It is easily recyclable and has a low potential for chemical leaching. However, it is not designed for repeated use as it can harbour bacteria and break down over time. Code 1 plastics should be stored in cool environments and not be reused.
While Code 1 plastics are generally considered safe, it is important to remember that even Bisphenol A-free plastics can break down when exposed to high heat. Therefore, it is recommended to avoid heating food in plastic containers or using them to store hot liquids. It is also advised to cut down on canned goods as many food cans are lined with BPA-containing resin.
To identify if a plastic product is BPA-free, one can check the materials used in the manufacturing process, interpret symbols, and observe. Some manufacturers boldly state "BPA-free" on their products, while others may include a recycling triangle with an arrow inside and the number 1, indicating that the product is made from PET and is BPA-free.

Bisphenol A (BPA) is a chemical used to harden plastics, often found in polycarbonate plastic
Bisphenol A (BPA) is a chemical produced in large quantities primarily for use in the production of polycarbonate plastics. It is also used in epoxy resins, which coat some metal food cans, bottle tops, and water supply pipes. Polycarbonate plastic is strong and durable, but it may break down over time from overuse at high temperatures. BPA is used to harden plastics, giving them exceptional resistance to mechanical, thermal, and chemical damage.
BPA is a chemical substance used in combination with other chemicals to manufacture certain plastics and resins. It is found in various products, including shatterproof windows, eyewear, water bottles, and epoxy resins. Polycarbonate plastic, a transparent and rigid type of plastic, is used to make water dispensers, food storage containers, and reusable beverage bottles.
BPA can migrate in very small amounts to food and drinks from the containers, so its safety is regularly reviewed. The primary source of exposure to BPA for most people is through food and beverages, although air, dust, and water are other possible sources. To identify if a plastic product contains BPA, you can look at 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 the presence of BPA.
Recycling codes 1, 2, 5, and 6 represent plastics that are commonly recycled and collected in residential and community recycling programs. Codes 3 and 7 plastics are more challenging to recycle and are generally not collected in public programs. Code 7 is a catch-all for all plastics that don't fit into codes 1 through 6. Only one type of code 7 plastic contains BPA—polycarbonate plastic. However, some polycarbonate items are BPA-free, and not all code 7 plastics contain BPA.
There have been concerns about the health effects of BPA exposure, especially for infants and children. To reduce potential health risks, some countries have introduced bans or restrictions on the use of BPA in certain products, such as baby bottles and food packaging. BPA-free plastics have also been introduced, manufactured using alternative bisphenols like bisphenol S and bisphenol F. However, there is controversy over whether these alternatives are safer.

Avoiding BPA: Opt for glass, stainless steel, or plastics free from Bisphenol A
Bisphenol A, or BPA, is an industrial chemical used in plastic manufacturing and added to many commercial products, including food containers, baby bottles, and plastic water bottles. It has been used since the 1960s to produce strong and resilient plastics for food packaging and home kitchen use.
Due to its widespread use, many people worry about BPA exposure. BPA can leach out of food or drink containers and into the food or beverages, and research suggests that most people over the age of 6 have measurable amounts of BPA in their urine.
To avoid BPA exposure, you can take the following steps:
- Check the labels or packaging of products for any statement about BPA presence.
- Look for products made from polypropylene ("5"), polyethylene (recycling code "1"), or polyethylene terephthalate ("1"), as BPA is often missing from products made from these plastics.
- Opt for glass or stainless steel containers and water bottles, especially for children. Glass is a safe alternative to plastic, and common food-grade stainless steel is called "series 304", 18/8 or 18/10 (which stands for 18% chromium and 8-10% nickel content).
- Avoid plastics marked with ""7", "PC", or "Other", as these may contain BPA or its substitutes, which may be just as harmful as BPA.
- Be cautious with Code 3 (PVC) products as they may contain BPA.
- Avoid heating plastics, as heat can cause additional BPA to leach out.
While some plastics are labelled "BPA-free", this does not necessarily mean they are safe. Some BPA-free plastics are made with other bisphenols, such as BPS and BPF, which may also disrupt the function of your cells. Therefore, it is important to limit or avoid plastics altogether, especially for foods and beverages, and opt for glass or stainless steel alternatives whenever possible.
