Plastic sandwich bags are a convenient way to store food, but concerns have been raised about the potential health risks associated with their use, particularly the presence of PFAS forever chemicals and BPA. PFAS chemicals are linked to serious health effects and have been found in plastic sandwich bags like Ziploc. BPA, or bisphenol A, is a chemical commonly used in the manufacture of plastic products and has been shown to encourage the growth of certain cancer cells. As a result, many people are seeking plastic sandwich bags that are PFAS and BPA-free. Some brands, like Ziploc, offer bags that are BPA-free and suitable for microwave and freezer use, while others offer eco-friendly and reusable options made from plant-based or silicone materials that are also PFAS and BPA-free.

What You'll Learn
Ziploc bags are BPA-free
Plastic sandwich bags are commonplace in most homes, and Ziploc is a popular brand. Ziploc bags are made from polyethylene, which is considered non-toxic. Polyethylene is not known to leach toxins, but it is important to note that any type of plastic can leach chemicals into food when exposed to high temperatures, fat, oil, or acidic foods. Therefore, it is recommended to use glass, metal, or lead-free ceramics for storing or serving hot, acidic, or high-fat foods.
Ziploc bags are marketed as being BPA-free, and this is true. Bisphenol-A (BPA) is a toxic compound commonly found in plastic food storage containers, milk-container liners, food cans, and water-supply pipes. It has been linked to the encouragement of growth in a specific category of prostate cancer cells. Ziploc bags do not contain BPA, and the brand's products are extensively evaluated for toxicity and safety. They comply with applicable quality and safety regulations.
However, it is important to note that while Ziploc bags are BPA-free, they may contain other potentially harmful chemicals. One concern is the presence of PFAS (polyfluoroalkyl and perfluoroalkyl substances), also known as "forever chemicals". PFAS have been linked to serious health effects and are very persistent in the environment. Mamavation, an independent organization, tested 11 popular plastic sandwich bags similar to Ziploc and found indications of PFAS.
Additionally, while Ziploc bags are safe for use in the microwave for defrosting or reheating food, they should not be used for sous vide cooking unless they are specifically the Ziploc Endurables® bags made with durable and reusable platinum silicone. Regular Ziploc bags are made with polyethylene, which has a softening point of 230°F, lower than the boiling point of water.

Plastic sandwich bags and PFAS forever chemicals
Plastic sandwich bags are typically made from polyethylene, which is considered non-toxic. However, an analysis by Mamavation found that 81% of the plastic sandwich bags tested showed indications of PFAS "forever chemicals". PFAS, or per- and polyfluoroalkyl substances, are used to make products stain-resistant, water-resistant, and oil-resistant. They are called "forever chemicals" because they do not naturally break down and have been linked to serious health issues, including cancer, liver problems, thyroid issues, and birth defects.
The presence of PFAS in plastic sandwich bags is concerning because these bags are often used for food storage. Food is a major source of PFAS exposure, and these chemicals can migrate at high levels into food and liquids. While some brands of plastic sandwich bags, such as Ziploc and Debbie Meyer Green Bags, have been found to be free of PFAS markers, it is important to recognize that there may be other harmful chemicals present in these products.
To reduce exposure to PFAS and other potentially harmful chemicals, it is recommended to use glass, stainless steel, or lead-free ceramic containers for food storage instead of plastic. These materials are less likely to leach chemicals into food and are generally considered safer for both human health and the environment.
While plastic sandwich bags may be convenient, it is important to be aware of the potential risks associated with their use. By understanding the chemicals present in these products and their potential impacts, consumers can make informed decisions about their food storage choices and take steps to reduce their exposure to harmful substances.
Additionally, it is worth noting that some plastic products, including certain food storage containers, have been found to contain Bisphenol A (BPA), a chemical that has been linked to encouraging the growth of specific categories of cancer cells. However, many plastic sandwich bag brands, including Ziploc, claim to be BPA-free and are extensively evaluated for toxicity and safety, complying with applicable regulations.

Plastic alternatives for food storage
Plastic sandwich bags and food storage bags are typically made from polyethylene, which is considered non-toxic. However, some plastic bags contain PFAS "forever chemicals", which are toxic and harmful to human health. These chemicals are also found in cookware, makeup, drinking water, contact lenses, and dental floss.
To avoid the potential health risks associated with plastic food storage, there are several alternative options available:
Glass Containers
Glass is a safe and non-toxic material that does not release chemicals into food, even when heated. It is easy to clean and can be recycled and reused. When choosing glass containers, opt for tempered or heat-resistant options. Glass jars from grocery stores, such as large peanut butter jars, can also be reused for food storage.
Stainless Steel
Stainless steel is another eco-friendly alternative for food storage. It is durable and does not release chemicals, making it a safe option for storing food.
Cloth Snack Bags
Cloth snack bags are a reusable and environmentally friendly alternative to disposable plastic sandwich bags. Look for 100% cotton snack bags, preferably organic, to minimize your environmental impact. These bags can be washed and reused, making them a long-lasting option.
Silicone Bags
Silicone bags are reusable and dishwasher-safe. However, they are not biodegradable, so they will not break down easily. When purchasing silicone bags, ensure they are food-grade and free from any chemical sprays.
Beeswax Wraps
Beeswax wraps are a natural and plastic-free alternative to plastic wrap. They are reusable, recyclable, and compostable, keeping your food fresh while reducing plastic waste.
Ceramic-Coated Cookware and Bakeware
Some companies offer ceramic-coated cookware and bakeware as an alternative to traditional non-stick options. These products are non-toxic and environmentally friendly, providing a safe option for preparing and baking food.
In addition to these alternatives, it is important to note that certain types of plastic should be avoided in food storage. For example, polystyrene (#6 PS) is often found in foamed food containers, but it can leach chemicals into food and is not recommended for kitchen use. When using plastic containers, avoid storing hot, acidic, or high-fat foods, as these can encourage the leaching of chemicals. Always wash plastic containers by hand with warm water and mild dish liquid, and avoid putting them in the dishwasher.

Safe plastic types for food storage
Plastic food storage containers are labelled with a recycling code number that indicates their safety for food storage. The safest plastic types for food storage are graded as numbers 2, 4, and 5.
Number 2 plastics are made from high-density polyethylene (HDPE) and are commonly used for milk bottles, juice containers, and laundry products. They are stiff and well-suited for packaging products with a short shelf life, but used milk jugs are not recommended for reuse as food storage containers as they are difficult to sanitise.
Number 4 plastics are made from low-density polyethylene (LDPE) and are used for bread and frozen food bags, squeezable bottles, and other types of packaging. LDPE is not known to leach toxins and is therefore safe for food storage.
Number 5 plastics are made from polypropylene (PP) and are used for bottles, food tubs, and reusable containers. PP is tough, flexible, and has high heat resistance, making it safe for use in the microwave and dishwasher. It is also chemical-resistant and does not leach toxins, making it a safe choice for food storage.
Other types of plastic, such as polystyrene (PS), are not recommended for food storage as they can leach chemicals into food. Bioplastics, labelled as number 7, may be used to store food safely, but it is important to check for additional identifying information as some number 7 containers may contain bisphenol-A (BPA), a toxic compound.
When choosing plastic food storage containers, it is important to look for those that are specifically designed for food storage and to avoid reusing containers that are not designed for this purpose. It is also recommended to avoid storing hot foods, acidic foods, or foods with a high fat or oil content in plastic containers, as these can encourage leaching.
