What You'll Learn
Food storage containers and refillable bottles
BPA, or bisphenol A, is a chemical used to make rigid plastics, including food storage containers and refillable drinks bottles. It is also used to make some protective coatings and linings for food and drinks cans.
Food storage containers are used to store weekly meal prep, leftovers, and to keep the refrigerator organised. The best containers are those that keep food fresh, don't leak, and hold up against stains. Some consumers prefer glass containers to avoid any possibility of chemical leaching of BPA, which is a hormone disruptor when consumed. However, most plastic is now BPA-free, and food contact material legislation currently sets restrictions on BPA which manufacturers are obliged to meet.
Polycarbonate plastic is a common material for food and drink containers, including refillable water bottles, baby bottles, and sippy cups. It is durable, impact-resistant, and clear, making it a popular choice. However, research has raised concerns about the health effects of BPA, which is used in the manufacture of polycarbonate. Studies have found that BPA can leak in trace amounts from polycarbonate containers and linings into food and drinks, especially when heated.
To avoid exposure to BPA, consumers can look for "`BPA-free`" labels on products, choose glass, porcelain, or stainless steel containers, and avoid heating polycarbonate containers in the microwave. Some companies market their products, especially those aimed at children, as being made of "food-safe, BPA-free" materials. While this is generally considered better than regular plastics, some concerns remain about the safety of alternative chemicals used in these products.
Scientists are currently evaluating the tolerable daily intake (TDI) of BPA, and regulatory bodies are considering updating restrictions on its use.

Protective coatings and linings for food/drink cans
Bisphenol A (BPA) is a chemical primarily used in the production of polycarbonate plastics and epoxy resins. It is used to make rigid plastics, including food storage containers and refillable drinks bottles. BPA is also used to make protective coatings and linings for food and drink cans.
The internal surface of food and drink cans is generally covered with polymeric coatings to preserve food and protect the metal substrate from corrosion. These coatings are complex formulations that contain different starting substances, such as monomers, prepolymers, and additives. During the manufacturing process, several compounds can be formed, such as reaction products and degradation products. These substances have the potential to migrate into the food, and many of them have not been identified or toxicologically evaluated.
In the 1950s, epoxy resins were introduced as coatings for aluminum and steel cans. Their stability, protective function, and technical properties made them the most commonly used coating material. Most epoxy coatings are synthesized from BPA and epichlorohydrin, forming bisphenol A-diglycidyl ether epoxy resins. However, other blended resins are also used, such as epoxy-phenolic coatings, epoxy amines, acrylates, and anhydrides.
To fulfill the technical and legal requirements, can coatings should withstand production and sterilization processes, be universally applicable for all food and beverage types, prevent chemical migration into food in harmful quantities, adhere to the can even after unintentional deformation, resist aggressive food types, and protect the metal of the cans.
There are concerns about the potential health effects of BPA exposure, especially for infants and children. Some studies suggest that they may be the most vulnerable to the effects of BPA. To address these concerns, legal restrictions have been put in place to limit the use of BPA in products intended for infants and young children, such as infant feeding bottles and beakers.

Polycarbonate plastic food containers
Polycarbonate is a type of plastic that is often used to make food storage containers. It is a strong and durable material that can resist staining, breaking, and chipping, making it ideal for long-term use in restaurants and other foodservice establishments. Polycarbonate food storage containers come in various sizes, ranging from a few quarts to larger options of up to 16.6 gallons. They are often clear, allowing for easy identification of the contents.
While polycarbonate plastic has many advantageous properties, there are some health concerns associated with its use in food containers. Polycarbonate plastic is made using a chemical called Bisphenol A (BPA), which has been the subject of extensive research due to its potential health effects. BPA is known to interfere with hormone systems and is classified as an endocrine disruptor. Although it is not considered harmful in low quantities, there are legal restrictions on its use in items intended for infants and young children, such as feeding bottles and beakers.
To reduce exposure to BPA, it is recommended to avoid microwaving polycarbonate plastic food containers, as high temperatures can cause the plastic to break down over time. Some plastics marked with recycle codes 3 or 7 may also contain BPA. Consumers are advised to opt for alternative materials like glass, porcelain, or stainless steel, especially when storing hot food or liquids.
It is important to note that regulatory agencies, such as the Food Standards Agency in the UK, have set restrictions on BPA levels in food contact materials. Manufacturers are obliged to meet these restrictions, and ongoing evaluations and research initiatives aim to address data gaps and inform decision-making regarding BPA use.
Overall, while polycarbonate plastic food containers offer durability and convenience, consumers should be aware of the potential presence of BPA and take appropriate measures to minimize their exposure, especially when it comes to infant and child care.

Polycarbonate polymer and epoxy resins
Bisphenol A, commonly known as BPA, is a chemical used primarily in the production of polycarbonate plastics and epoxy resins. Polycarbonate materials are used in various products, from CDs to food storage containers, sports safety equipment, and medical devices. Polycarbonate is a highly shatter-resistant, lightweight, and optically clear thermoplastic, making it unique among commercially available thermoplastics.
Epoxy resins, typically derived from BPA, are thermoset plastics known for their toughness, chemical resistance, and high adhesion. They are widely used in coating applications and high-strength/lightweight composites. Epoxy resin is also used as an inner coating on metal food and beverage containers to prevent corrosion.
The safety of BPA has been a subject of debate, particularly regarding its use in food packaging. While some studies suggest that exposure to BPA can interfere with hormone systems (making it an endocrine disruptor), other assessments conclude that BPA consumption from food contact with polycarbonate plastic and epoxy resin is minimal and does not pose a significant risk to human health.
Regulatory agencies, such as the Food and Drug Administration in the United States, have conducted safety reviews of BPA. The National Institute of Environmental Health Sciences (NIEHS) and the National Toxicology Program (NTP) are actively researching the potential health effects of BPA exposure.
To address concerns, manufacturers can use alternative materials or choose BPA-free products, especially for items intended for infants and young children, where legal restrictions on BPA usage already exist.

Plastic alternatives to glass
Plastic is a versatile material that has been used as an alternative to glass in various applications. While glass has been the primary material for windows since Roman Egypt, plastic alternatives have gained popularity due to their advantages in specific contexts. Two commonly used plastic alternatives to glass are acrylic (also known as plexiglass) and polycarbonate.
Acrylic sheeting, or plexiglass, is a popular alternative to glass windows due to its cost-effectiveness, lightweight properties, and ease of installation. It is cheaper to produce and transport than glass, resulting in significant cost savings for manufacturers, business owners, and consumers. Acrylic windows are also safer than glass as they do not shatter into dangerous shards when broken. Additionally, acrylic offers superior light transmission, with over 90% of light passing through, and does not exhibit glare or reflections. Its resistance to UV rays prevents discolouration and degradation, ensuring long-term clarity and durability.
Polycarbonate is another plastic alternative to glass, known for its exceptional impact resistance and structural strength. It is 250 times stronger than glass and 30 times stronger than acrylic, making it ideal for facilities requiring high security and durability, such as schools, subways, and psychiatric facilities. While polycarbonate is more expensive than acrylic and glass, its superior strength and safety make it a preferred choice in specific applications.
In addition to windows, plastic alternatives to glass can be found in food storage and tableware. Pottery and fired ceramics provide a stable and waterproof option, while stainless steel, porcelain, and glass containers are recommended for hot food or liquids to reduce exposure to chemicals like Bisphenol A (BPA), commonly found in plastic food containers.
BPA is a chemical primarily used in producing polycarbonate plastics and epoxy resins. It is often found in food storage containers, refillable drink bottles, and protective coatings for food and drink cans. While legal restrictions prohibit the use of BPA in infant and young children's products, concerns have been raised about its potential health effects, especially for vulnerable populations. To reduce BPA exposure, individuals can opt for glass, porcelain, or stainless-steel containers and minimise the use of canned foods.
