Tupperware is a household name that has been associated with plastic food storage containers for decades. The brand was founded by Earl Supper in the 1940s to promote thrift and cleanliness, and its pastel-coloured plastic containers quickly became a symbol of postwar consumer culture in America. Most Tupperware containers are made from plastics #4 or #5, which are considered safe for repeated use in storing food. However, some Tupperware products are made from polycarbonate, #7 plastic, which has been shown to release the harmful, hormone-disrupting chemical Bisphenol A (BPA) into food after repeated use. This has raised concerns about the potential health hazards of using certain types of Tupperware, especially when heated or damaged.

Some Tupperware products are made from polycarbonate #7, which can leak Bisphenol A (BPA)
Tupperware is a well-known household brand that has been around for decades. The majority of Tupperware containers are made from plastics #4 or #5, which are considered safe for repeated use in storing food. However, some Tupperware products are made from polycarbonate #7, which has been shown to leak Bisphenol A (BPA), a harmful and hormone-disrupting chemical, into food items after repeated use.
Bisphenol A (BPA) is a chemical that has been commonly used in the production of certain plastics to make them more durable and shatter-resistant. However, BPA exposure has been linked to various health issues, including infertility and altered fetal growth. The US Institute of Environmental Health Sciences has stated that BPA acts like estrogen, a powerful hormone crucial for reproduction, fertility, sex organ development, brain development, and metabolism regulation.
The following Tupperware products are made from polycarbonate #7: the Rock ‘N Serve microwave line, the Ice Prisms line, the Meals-in-Minutes Microsteamer, the “Elegant” Serving Line, the TupperCare baby bottle, the Pizza Keep’ N Heat container, and the Table Collection. It is important to note that the last three products on this list are no longer being made but might still be found in kitchens.
To minimize health risks, it is recommended to avoid using plastic containers made from polycarbonate #7 for storing food items. Consumers should opt for Tupperware products made from plastics #4 or #5, which are safer for repeated use. Additionally, transferring food from a plastic container to a glass bowl before microwaving is advised, as the "microwave-safe" label on plastic containers does not guarantee health safety.
It is worth mentioning that Tupperware offers a lifetime guarantee and will replace broken or damaged items for free. This can be beneficial for maintaining safe and durable food storage containers.

BPA is a harmful chemical that can cause health issues such as infertility and fetal growth alterations
Tupperware is a well-known household name that has been associated with food storage containers for decades. Most Tupperware containers are made from #4 or #5 plastics. However, some products are made from polycarbonate, #7, which has been shown to leak Bisphenol A (BPA), a harmful, hormone-disrupting chemical, into food items after repeated use.
Bisphenol A (BPA) is a chemical that has been used for years in the production of certain plastics to make them more durable and shatter-resistant. Unfortunately, it poses potential health hazards. The majority of daily exposure to BPA happens through our diet.
BPA has been linked to female infertility, with higher levels of BPA detected in infertile women. It has been found to negatively affect natural conception and spontaneous fecundity. Exposure to BPA during early life may also have transgenerational effects, increasing the risk of developing BPA-related diseases in subsequent generations.
In studies on rodents, prenatal exposure to BPA has been shown to alter reproductive development and ovarian morphology. Similarly, in human studies, prenatal BPA exposure has been associated with concerns about ovarian function. Exposure to BPA during pregnancy can also cause permanent abnormalities in the uterus of offspring, including alterations in their DNA, which can affect sensitivity to estrogen. These epigenetic alterations can be carried throughout adulthood, indicating that exposure to BPA as a fetus may have long-lasting consequences.
Therefore, it is essential to be cautious when using plastic containers, especially those made with polycarbonate, and to avoid heating food in plastic containers, as this can increase the leaching of chemicals into food.

Microwave-safe Tupperware may not be safe from a health standpoint as chemicals can transfer from plastic to food during heating
Tupperware is made from a variety of plastics, with most containers made from #4 or #5 plastics. However, some Tupperware products are made from polycarbonate, #7, which has been shown to leak harmful chemicals, such as Bisphenol A (BPA), into food items after repeated use. BPA is a chemical that has been used for years in the production of certain plastics to make them more durable and shatter-resistant. However, it can also make them potential health hazards, as BPA exposure has been linked to a higher risk of various health issues, such as infertility, altered fetal growth, attention deficit hyperactivity disorder, aggression in children, polycystic ovarian syndrome, endometriosis, and heart disease.
While many plastic containers are designed to withstand high microwave temperatures, the "`microwave-safe`" label on some plastic containers does not guarantee that the product is entirely safe from a health standpoint. Health experts warn that dangerous chemicals can migrate from plastic containers into food during heating. Discoloration of a container can indicate that a chemical change has occurred in the plastic, and that the plastic is degrading and breaking down. Therefore, it is recommended to transfer food from a plastic container to a glass bowl before microwaving it.
Plastics with the label "PC" (polycarbonate) or recycling codes 3 or 7 likely contain BPA, and products with these labels should be replaced with glass, porcelain, ceramic, or stainless-steel containers. While single-use plastics should never be reused, all plastics break down over time and with repeated use or washings, increasing the likelihood of chemical migration into food. To reduce chemical exposure, avoid allowing plastic wrap to come into contact with food, especially during heating, and opt for glass or ceramic containers for microwaving food and beverages.
It is important to note that food packaging materials are regulated by the FDA, which reviews the safety of packaging components that can reasonably be expected to migrate into food, even in tiny amounts. However, given the potential health risks associated with chemical migration from plastic containers, it is advisable to take precautions, such as using alternative containers for microwaving and avoiding single-use plastics.
