Tupperware has long been a go-to brand for food storage, valued for its durability and convenience. Yet, as our understanding of safe materials has grown, so have the guidelines surrounding plastic containers, especially older models.

If you own vintage Tupperware—specifically those produced before 2010—it’s important to know the best practices for ensuring safety in your kitchen.

Should Old Tupperware be Thrown Out?

Old Tupperware should be thrown out if it shows signs of damage, has persistent stains and odours, is made with BPA, or is no longer functional. Containers with cracks, chips, scratches, or warping, can harbour bacteria and may leach chemicals into food. 

Similarly, containers with stubborn stains and odours may indicate lingering food residue or bacteria, even if they are not necessarily unsafe. 

Potential Health Concerns with Vintage Tupperware

Old Tupperware items, particularly those made before 2010, may contain materials like bisphenol-A (BPA), a chemical previously used in plastics but now removed from newer Tupperware due to safety advancements.

Research has connected BPA exposure with various health risks, such as fertility issues, developmental delays in children, and heart disease. Frequent heating or washing (especially at high temperatures) of these plastic food containers may increase the chances of BPA leaching into food.

To identify the type of plastic your Tupperware is made from, look for a number on the bottom. Containers marked with a "7" might contain BPA, while numbers "1," "2," or "5" generally indicate BPA-free materials. However, even BPA-free plastics can release certain chemicals, especially when exposed to high temperatures.

Signs It’s Time to Replace Your Tupperware

If you’re uncertain whether to keep or replace your old Tupperware, look for these indicators:

Stains and Odours

Persistent stains or lingering smells suggest that the plastic has absorbed food particles, making it difficult to clean thoroughly. While discolouration alone may not affect safety, odours indicate that food residue may be trapped in the container.

Warping, Cracks, and Chips

Physical damage like warping, cracks, and chips can compromise the container's structure, potentially harbouring bacteria in hard-to-clean areas. Damaged surfaces can also lead to leaks and make the container unsafe for food storage.

Damaged Lids

A container’s lid plays a vital role in maintaining freshness and preventing spills. If the lid is warped, cracked, or otherwise deformed, it may no longer provide an effective seal, risking food contamination.

Age

Containers older than 2010 may contain BPA, a compound linked to issues such as hormone disruption, diabetes, and heart conditions. Even if these items appear to be in good shape, they are more prone to wear and may leach BPA, especially when used with warm foods or in the microwave.

Eco-Friendly Ways to Repurpose or Dispose of Unwanted Tupperware

If you decide to part with older containers, consider eco-friendly options to give them a new purpose or dispose of them responsibly:

Donating

In good condition, old Tupperware may still be usable for non-food purposes. Some thrift stores accept gently used containers, but it’s wise to call ahead as policies vary due to potential food safety concerns.

Selling

Vintage Tupperware holds appeal for collectors, particularly if it features unique colours or designs. Online platforms like eBay or Etsy allow you to list these items, but be sure to disclose their age and inform buyers that vintage Tupperware may not be food-safe due to potential BPA content.

Recycling

Not all types of plastic Tupperware are recyclable. Look for numbers on the bottom of the container: plastics marked with "1," "2," and sometimes "5" are generally recyclable. We recommend calling local recycling facilities ahead to determine if your specific containers are recyclable. 

Upcycling

Old Tupperware can find a second life around the house in creative ways. Use it as a planter, organiser, compost bin, or even as storage for craft supplies or first-aid items. This reduces waste and extends the item’s usefulness beyond food storage.

Sustainable Alternatives for Food Storage

Replacing older plastic food containers is a great opportunity to choose environmentally-friendly storage solutions. Here are a few sustainable options:

• Glass: Glass containers offer durability and safety, as they don’t release chemicals into food. They also have high recycling rates, making them an eco-conscious choice. However, producing glass involves sand extraction, which has environmental impacts on river and seabeds.
  
  
• Bamboo: Bamboo containers provide a biodegradable and renewable alternative to plastic. With proper care, they can last for years. To prevent mould, avoid storing very moist foods in bamboo containers and keep them dry.
  
  
• Stainless Steel: Known for durability, stainless steel is another excellent option for food storage. Resistant to rust, staining, and chemical leaching, it’s also recyclable, with many products made from recycled steel.

FAQs 

What is the recycling code for plastic food storage containers?

The Recycling Code is a numbered system that identifies different types of plastic products, like containers or plastic bags. For example, #1 (polyethylene terephthalate), #2 (High-density polyethylene), and #4 (Low-density polyethylene) are commonly recycled, while #3 (Polyvinyl Chloride) and #7 are usually not accepted. We recommend checking with your local recycling centre ahead of time if your items are recyclable.

Are old plastic containers safe to use for storing hot food or acidic foods?

Older containers may contain BPA, a chemical that can leach into food, especially when exposed to heat or acidic foods like tomatoes. It is generally recommended to avoid using old plastic containers for hot food and to choose glass containers instead.

How do I know if my plastic containers are BPA-free?

Many plastic containers made after 2010 are BPA-free, but checking the container for a label can be helpful. 

What are some eco-friendly alternatives to using plastic containers to keep my food fresh?

Glass containers are a great alternative to plastic because they are chemically inert, recyclable, and do not retain odours. Other sustainable options include stainless steel and bamboo containers.
