Does Tupperware Go Bad?
Tupperware has a lifespan exceeding 10 year if handled carefully, however they can discolor and crack over the years. If you expose the Tupperware container to fire, it can quickly melt and lose shape.
Additionally, old Tupperware are likely to be badly stained and exposed to strong odors.
Overtime, Tupperware containers permeate stains and odor due to different food stored, especially with acidic foods like tomato sauce or garlic odor left behind. These stains or odor do not remove easily and when not taken care of right away can reduce the life expectancy of the container.
Determining whether or not the Tupperware is in good or bad condition depends on how well you care for it. All Tupperware-brand plastic containers should be washed with a soft sponge and a non-abrasive cleaner.

When Should I Throw Away Tupperware?
Plastic containers help in keeping leftovers safe in the fridge or freezer, and are also useful for carrying food for lunch. They are light and less delicate compared to glass and ceramic.
However, these containers do not last forever, and they might end their natural lifespan. When the container is old enough, throw it away.
Here are few instances when you should throw away those Tupperware:
- Misplaced or Broken Lid: The container is only helpful if it has a lid. If the top is lost, and you don’t seem to find the right one to seal your container, it may not be useful anymore. Always take time to match the lids at least once a year and check if containers are in good condition so you can dispose or replace.
- Older Than 10 Years: Old plastics are associated with the danger of leaching harmful chemicals known as BPA and phthalates. These chemicals are toxic and can pose various health risks when ingested. Tupperware has stopped manufacturing with these harmful additives, but if you are using a container older than ten years then it’s probably not safe.
- Physical Damage: In case you placed the plastic container too close to the stove and it got burnt, or scratched up on the bottom, it’s time to dispose of it. If you alter the smooth surface of the container, there is a possibility that the material is compromised. Such materials increase the chance of leaching harmful plastic chemicals into your food if you continue using it to reheat or store food.
- Don’t Like It: If you don’t like the storage containers, maybe it is too big or too small to adequately hold anything. Perhaps you don’t like the color, or the lids are no longer sealing appropriately. It’s just a sign that you should let go.
- Stained or Stinky: If it’s no longer easy to wash the stains from the container, and the smell is so bad with no end in sight, it’s time to replace the container. Holding onto a stained or stinky container can ultimately affect the food that is stored inside.
How Long Should You Keep Plastic Tupperware?
Many people hold plastic for an extended period since they are convenient for keeping leftovers, storing beans, and various dry products. It would be best if you let go of plastics because they contain toxic chemicals that can leach into your food.
Some plastic containers have a lifespan of 5-10 years, as long as they are in good condition, while others can only last for a few months even if handled gently.
There really is no specific time frame that you should use a plastic container. However, it would be best to dispose of them immediately; they crack or lose their color. If your containers are already losing their shape, having nasty stains, or you have held them for such a long time that you don’t know where they came from, then it’s probably time to replace them.
What Should I Do with Old Tupperware?
Tupperware plastics are convenient and practical, but they also have a particular lifespan. When they become old and lose shape, it’s time to transition them to another usage instead of food storage.
