When you think of a typical kitchen, images of neatly stacked containers filled with leftovers come to mind, and for many, this includes trusty old Tupperware. This innovative plastic ware revolutionized food storage when it first came onto the market in the mid-20th century. However, as time passes and our understanding of plastics improves, many wonder: Is old Tupperware safe to use for food? In this article, we’ll explore the safety of vintage Tupperware, scrutinize the materials used, and provide insights to help you decide whether to keep or discard these old kitchen staples.
The History of Tupperware
Tupperware was introduced in 1946 by Earl Tupper, a veteran of World War II who sought to create a functional and durable solution for food storage. The innovative design of Tupperware, featuring airtight seals, quickly gained popularity. By the 1950s and 1960s, Tupperware parties became a social phenomenon, making it a household name.
Throughout the years, Tupperware products have evolved significantly, both in design and materials used. Originally, Tupperware was made from a type of plastic called polyethene. As knowledge about plastics grew, the company began to use various additives and materials that enhanced the products’ performance but sometimes raised safety concerns.
The Materials Used in Tupperware
To grasp the safety of old Tupperware, it’s essential to understand the types of materials used in its production throughout the years.
Common Plastics in Tupperware
The primary materials in Tupperware include:
- Polyethylene (PE): This was the primary plastic used in early models. It’s known for being flexible, durable, and resistant to moisture.
- Polypropylene (PP): This plastic became increasingly popular due to its higher heat resistance and clarity. It is commonly used in microwave-safe containers.

What is Tupperware made of?
Tupperware is primarily made from a variety of plastics, most notably polyethylene and polypropylene. These materials are known for their durability and flexibility, which makes Tupperware a popular choice for food storage. Over the years, Tupperware has evolved, and newer products may utilize safer formulations designed to withstand high temperatures and resist staining and odors.
Historically, Tupperware produced between the 1940s and the early 2000s may contain older types of plastics, some of which were manufactured with additives like bisphenol A (BPA). BPA has been linked to various health concerns, prompting manufacturers to shift toward safer alternatives. If you’re unsure about the material used in your old Tupperware, check for any identifiable marks or contact the company for specific details.
Is it safe to use old Tupperware for food storage?
Using old Tupperware can be safe, but caution is warranted. Items manufactured before the 1990s are more likely to contain harmful chemicals like BPA, which can leach into food, especially when exposed to heat. If your old Tupperware is stained, warped, or scratched, it’s best to replace it, as these conditions can also diminish its safety and efficiency for food storage.
To be sure about the safety of your older Tupperware, consider checking labels for recycling codes or contacting the manufacturer for product information. If you don’t have historical details on the product and are concerned, it may be prudent to use the containers for non-food storage or consider replacing them with modern, BPA-free options.
How can I identify if my Tupperware contains BPA?
Identifying if your Tupperware contains BPA can be tricky, especially with older pieces that may lack clear labeling. A good first step is to check for a recycling symbol, which is typically located on the bottom of the container. If the recycling code is “3” or “7,” there’s a chance it may contain BPA. However, some newer plastics also bear the “7” code but are not harmful, so further scrutiny might be necessary.
Additionally, you can look for any brand-specific identification. Tupperware has undergone many changes over the years, and pieces manufactured after 2010 are highly likely to be BPA-free. If you’re still unsure, consider reaching out to Tupperware through their official website or customer service for detailed information based on your piece’s production date.
