Tupperware, a household name synonymous with plastic containers, has been a staple in kitchens for decades. Many of us have inherited or collected vintage Tupperware pieces, particularly those from the 1970s, which are highly prized for their retro aesthetic and durability. However, with growing concerns about plastic safety and the potential health risks associated with using old plastic containers, many are left wondering: is 1970s Tupperware safe to use?
A Brief History of Tupperware
To understand the safety of 1970s Tupperware, it’s essential to delve into the company’s history and the materials used during that era. Tupperware was first introduced in the 1940s by Earl S. Tupper, who developed a revolutionary airtight container made from a type of plastic called Polyethylene. This innovative design kept food fresh for longer periods, making it an instant hit among homemakers.
In the 1970s, Tupperware continued to evolve, introducing new products and designs that became iconic symbols of the decade. The company’s use of plastic materials, however, has raised concerns about the potential health risks associated with using these containers.
The Safety Concerns Surrounding 1970s Tupperware
The primary concern surrounding 1970s Tupperware is the presence of chemicals like Bisphenol A (BPA) and Phthalates, which were commonly used in plastic production during that era. These chemicals have been linked to various health problems, including cancer, reproductive issues, and hormonal imbalances.
Bisphenol A (BPA)
BPA is a chemical used in the production of polycarbonate plastics, which were widely used in Tupperware containers during the 1970s. BPA has been shown to leach into food, particularly when heated or exposed to acidic or fatty substances. This leaching can lead to the ingestion of BPA, which has been linked to various health problems.
Phthalates
Phthalates are another type of chemical used in plastic production, particularly in PVC (polyvinyl chloride) plastics. These chemicals have been linked to reproductive issues, birth defects, and hormonal imbalances. Phthalates can also leach into food, especially when stored in PVC containers.
Assessing the Safety of 1970s Tupperware
While the presence of BPA and Phthalates in 1970s Tupperware is a concern, it’s essential to assess the actual risk of using these containers. Several factors can influence the safety of vintage Tupperware, including:
Material Type
Not all 1970s Tupperware containers are created equal. Some were made from polyethylene, which is generally considered safer than polycarbonate or PVC plastics. However, it’s crucial to identify the type of plastic used in your vintage Tupperware to assess its safety.
Condition and Age
The condition and age of your 1970s Tupperware can also impact its safety. Containers that are cracked, faded, or show signs of wear may be more likely to leach chemicals into food. Additionally, older containers may have undergone more degradation, increasing the risk of chemical leaching.
Usage and Storage
How you use and store your 1970s Tupperware can also affect its safety. Avoid using these containers for storing acidic or fatty foods, as these can increase the risk of chemical leaching. Additionally, avoid heating food in vintage Tupperware, as this can cause chemicals to leach into the food.
Alternatives to 1970s Tupperware
If you’re concerned about the safety of your 1970s Tupperware, consider replacing it with safer alternatives. Modern Tupperware products are made from BPA-free and Phthalate-free materials, ensuring a safer storage solution for your food.

Is 1970s Tupperware safe to use?
The safety of 1970s Tupperware depends on various factors, including the type of plastic used, the condition of the container, and how well it has been maintained. Tupperware produced in the 1970s may contain chemicals like Bisphenol A (BPA) and phthalates, which have raised health concerns in recent years. However, it’s essential to note that not all vintage Tupperware contains these chemicals, and some products may be safer than others.
To determine the safety of your 1970s Tupperware, inspect the container for any signs of wear and tear, such as cracks, scratches, or discoloration. If the container is in good condition and has been properly cared for, it may still be safe to use. However, if you’re unsure about the safety of your vintage Tupperware, it’s best to err on the side of caution and replace it with a newer, BPA-free alternative.
What types of plastics were used in 1970s Tupperware?
Tupperware produced in the 1970s was made from a variety of plastics, including polyethylene, polypropylene, and polycarbonate. Polyethylene and polypropylene are generally considered safe and are still widely used in food storage containers today. However, polycarbonate plastics, which were commonly used in Tupperware’s popular “Wonder Bowl” and “Tupperware Party” lines, may contain BPA, a chemical that has been linked to various health problems.
It’s worth noting that Tupperware began phasing out the use of polycarbonate plastics in the 1990s, and by the early 2000s, the company had switched to using BPA-free plastics in all of its products. If you’re concerned about the type of plastic used in your vintage Tupperware, you can contact Tupperware’s customer service department for more information or check the manufacturer’s mark on the bottom of the container.
How can I identify BPA-free 1970s Tupperware?
Identifying BPA-free 1970s Tupperware can be challenging, as the company didn’t begin labeling its products as “BPA-free” until the 2000s. However, there are a few ways to determine whether your vintage Tupperware may contain BPA. Check the manufacturer’s mark on the bottom of the container for a “PC” or “7” symbol, which indicates that the product is made from polycarbonate plastic and may contain BPA.
If you’re still unsure about the safety of your 1970s Tupperware, you can also look for products that are made from polyethylene or polypropylene, which are generally considered safe. These plastics are often marked with a “2” or “5” symbol on the bottom of the container. Keep in mind that even if your vintage Tupperware is BPA-free, it’s still important to inspect the container for any signs of wear and tear before using it.
Can I still use my 1970s Tupperware for storing food?
While it’s technically possible to use your 1970s Tupperware for storing food, it’s essential to exercise caution and consider the potential risks. If your vintage Tupperware contains BPA or other chemicals, it may leach into your food, especially if you’re storing fatty or acidic foods. Additionally, if the container is damaged or worn out, it may harbor bacteria or other contaminants that can make you sick.
If you still want to use your 1970s Tupperware for storing food, make sure to inspect the container carefully before each use and wash it thoroughly with soap and warm water. You can also consider using your vintage Tupperware for storing non-food items, such as craft supplies or office materials, to minimize the risk of contamination.
How can I care for my 1970s Tupperware to ensure it remains safe to use?
To keep your 1970s Tupperware safe to use, it’s essential to care for it properly. Avoid exposing the container to extreme temperatures, such as leaving it in a hot car or putting it in the freezer. You should also avoid using abrasive cleaners or scouring pads, which can damage the plastic and create scratches that can harbor bacteria.
Instead, wash your vintage Tupperware with mild soap and warm water, and dry it thoroughly after each use. You can also sanitize your Tupperware by washing it in a mixture of equal parts water and white vinegar. By following these care tips, you can help extend the life of your 1970s Tupperware and ensure it remains safe to use.
Can I replace the lids or seals on my 1970s Tupperware?
If the lids or seals on your 1970s Tupperware are damaged or worn out, you may be able to replace them. Tupperware offers replacement parts for many of its vintage products, including lids and seals. You can contact the company’s customer service department to inquire about availability and pricing.
However, if you’re unable to find replacement parts from Tupperware, you may need to consider replacing the entire container. This is especially true if the lid or seal is damaged in a way that compromises the safety of the container. In some cases, it may be more cost-effective and safer to replace your vintage Tupperware with a newer, BPA-free alternative.
Is it worth collecting and using vintage Tupperware?
Whether or not it’s worth collecting and using vintage Tupperware depends on your personal preferences and priorities. If you’re a collector or enthusiast, you may appreciate the nostalgic value and aesthetic appeal of vintage Tupperware. Additionally, many vintage Tupperware products are still functional and can be used for storing food or other items.
However, if you’re concerned about safety and health risks, you may want to consider using newer, BPA-free alternatives. Ultimately, the decision to collect and use vintage Tupperware is up to you. If you do decide to use your vintage Tupperware, make sure to inspect it carefully and follow proper care and maintenance tips to minimize the risk of contamination.
