Tupperware is a well-known brand of plastic food storage containers. Most Tupperware containers are made from plastics #4 or #5, which are considered safe for repeated use with food. However, some Tupperware products are made from polycarbonate, #7 plastic, which has been shown to leak harmful, hormone-disrupting chemicals like Bisphenol A (BPA) into food items after repeated use. This is especially true when these containers are heated, as the chemicals can leach into the food. Therefore, it is important to understand the type of plastic used in Tupperware products to ensure safe usage and avoid potential health hazards.

What You'll Learn
Tupperware is made from plastics #4, #5, and #7
BPA exposure has been linked to a higher risk of a wide range of health issues, such as infertility and altered fetal growth. Even low levels of BPA that leach from consumer plastics have been associated with potential harm. Discoloration of a container can signal that a chemical change has occurred in the plastic, indicating that the plastic is degrading and breaking down.
Plastics #1, #3, #6, and #7 are known to leach toxic chemicals into their contents when reused. For example, water bottles are often made from the resin #1 polyethylene terephthalate (PET or PETE), which is generally safe for single use but can leach chemicals such as DEHA and BBP when reused. Tupperware, invented by Earl Tupper in the 1940s, has become a household name for its durable and shatter-resistant plastic food storage containers. While some Tupperware products may contain BPA, the brand offers a lifetime guarantee and will replace broken or damaged items for free.

#7 plastic is unsafe and can leak harmful chemicals
Tupperware is a well-known kitchen brand that has been a household name for decades. Most Tupperware containers are made from #4 or #5 plastics, 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 have some safety concerns.
#7 plastic is a category that includes various kinds of plastic and can sometimes be challenging to recycle. It is important to understand the specific composition of #7 plastic to determine whether it can be recycled effectively. While not all #7 plastics are toxic, there are significant potential hazards associated with their use, especially in products that come into contact with food and drinks.
One of the main concerns with #7 plastic is its potential to leak harmful chemicals, such as Bisphenol A (BPA), into food items after repeated use. BPA is a chemical that has been used in the production of certain plastics to make them more durable and shatter-resistant. However, exposure to BPA has been linked to various health issues, including infertility and altered fetal growth. Even low levels of BPA that leach out of consumer plastics have been shown to be associated with harm.
Discoloration of a plastic container can indicate that a chemical change has occurred and that the plastic is degrading. This can lead to an increased interaction between the food and the plastic, potentially resulting in more chemicals being transferred to the food during heating. Therefore, it is recommended to transfer food from a plastic container to a glass bowl before microwaving it.
Overall, while not all #7 plastics are unsafe, it is important to exercise caution when using them, especially for food storage. It is advisable to avoid using #7 plastic products that come into direct contact with food and drinks to minimize potential health risks associated with chemical leakage.

Plastics #2, #4, and #5 are the safest for food storage
When it comes to food storage, not all plastics are created equal. Some plastics can leach harmful chemicals into food, especially when heated, while others are considered safe for repeated use. So, which plastics are best for storing food?
Plastics #2, #4, and #5 are widely recognised as the safest for food storage. These plastics are commonly used for food packaging and are considered safe for repeated use. They include:
- HDPE (#2): High-Density Polyethylene is a stiff and rigid plastic often used for milk bottles, juice containers, and laundry products. It is FDA-approved, lightweight yet durable, and resistant to chemicals and corrosion. However, it should not be used for hot foods as heat can break down its chemical bonds, making it unsafe.
- LDPE (#4): Low-Density Polyethylene has a lower tensile strength than HDPE, making it more flexible. It is commonly used for bread and sandwich bags and is easily reusable, though not always recyclable.
- PP or Polypropylene (#5): This plastic is FDA-approved for food contact and is safe for repeated use. It has a high melting point, making it microwave and dishwasher-safe. It is lightweight, flexible, and durable, ideal for food storage containers and condiment bottle caps.
Using plastics #2, #4, and #5 for food storage helps prevent accidental toxin ingestion and reduces the risk of serious health issues associated with other plastics.
It is important to note that while these plastics are considered safe, food-grade does not always mean food-safe. The intended use of the plastic should be followed to prevent safety hazards. For example, a plastic container meant for dry cereal may not be safe for storing hot foods. Additionally, some plastics, like #1 PET or PETE, are safe only for single-use and should be avoided if left in direct sunlight or heated, as they can leach harmful chemicals.
When it comes to Tupperware, most of their containers are made from plastics #4 or #5, which are generally considered safe. However, some Tupperware products were made from polycarbonate (#7), which has been shown to leach Bisphenol A (BPA), a harmful, hormone-disrupting chemical, into food after repeated use. While Tupperware may be convenient, it is always a good idea to understand the type of plastic used and its potential impact on your health and the environment.

Plastic containers labelled 'microwave safe' may not be safe
Tupperware, a well-known kitchen brand, has been a household name for decades. Most Tupperware containers are made from #4 or #5 plastics, 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 harmful, hormone-disrupting chemicals like Bisphenol A (BPA) into food items after repeated use.
While plastic containers labelled as microwave-safe are generally considered safe to use, there are still some concerns about potential health risks. The "microwave safe" label on plastic containers does not guarantee that the product is entirely safe from a health standpoint. It is important to understand that some plasticizers and chemicals can transfer from the plastic containers into the food during heating. Discoloration of a container can indicate that a chemical change has occurred in the plastic, suggesting that the plastic is degrading and breaking down.
Polystyrene containers, for example, are well-known for their excellent insulation properties, but they should not be placed directly in the microwave. Similarly, paper products should be avoided in the microwave due to coatings, seals, or glues that may be present. When using plastic containers in the microwave, it is recommended to follow the instructions on the label and use glass or ceramic alternatives whenever possible.
Single-use plastic containers, like margarine tubs, tend to warp or melt in the microwave, allowing more substances from the plastic to leach into the food. It is important to let food cool before placing it in a plastic container and then store it in the fridge immediately. Additionally, plastic water bottles, which are typically made from #1 polyethylene terephthalate (PET or PETE), should only be used once, as reusing them can lead to the leaching of chemicals such as DEHA and benzyl butyl phthalate (BBP), which have potential health risks.
To ensure the safety of your food, it is crucial to understand the type of plastic used in your containers and follow the appropriate guidelines for microwave usage. While microwave-safe labels provide some assurance, staying informed about the potential risks associated with different types of plastics can help make healthier choices.

Tupperware offers a lifetime guarantee on its products
Tupperware is a well-known brand of plastic food storage containers. Most Tupperware containers are made from plastics categorized as #4 or #5, which are considered safe for repeated use in storing food. However, some Tupperware products were made from polycarbonate, #7, which has been shown to leak harmful chemicals, such as Bisphenol A (BPA), into food items after repeated use.
Given the potential health hazards associated with BPA, it is important to understand the safety and longevity of Tupperware products. Tupperware offers a Limited Lifetime Warranty for most of its products, assuring customers that their products will not chip, crack, break, peel or warp under normal, non-commercial use for the lifetime of the product. This warranty does not cover products with specific exclusions, and customers may be required to send the affected item to Tupperware for evaluation, bearing the shipping and handling charges.
The Limited Lifetime Warranty provides peace of mind for customers, ensuring that their Tupperware products are protected against defects in material or workmanship. If a product covered by the warranty fails to meet these standards, Tupperware will either replace it with a similar product or provide a credit towards future purchases.
It is worth noting that Tupperware's definition of "normal use" does not include heating the products in a microwave, even if they are labelled "microwave-safe". Heating plastic containers can cause plasticizers and chemicals to transfer into the food, posing potential health risks. Discoloration of a container is a sign of chemical change and degradation, indicating that the plastic is breaking down.
While Tupperware's Limited Lifetime Warranty does not specifically mention BPA, the company has officially stated that all their containers have been BPA-free since March 2010. This suggests that Tupperware products manufactured before this date may contain BPA, which could pose health risks with repeated use.
