There are some exceptions to this rule, but for the most part, don't store Tupperware containers with the lids on. It may seem counter-intuitive, but you waste so much space by doing this. Keeping lids separate makes for a more manageable Tupperware organization system overall.
Stack Vertically
If you have abundant space to store Tupperware like this full cupboard, keeping the lids on the Tupperware and stacking each container on top makes sense. Not only does this create a visually pleasing system, but you only have to grab one thing and have both the top and the bottom ready to go.
I always encourage my clients to keep the box part and the lids separate. The lids you can store standing upright, but the box should be stacked together. This way, you can maximize your storage space.
With vintage Tupperware products, dangerous elements (read: potentially toxic chemicals) come into play. If your Tupperware is old enough, it might even leach harmful chemicals and heavy metals like cadmium, lead, and arsenic into stored food.
“Every single time that they're used, they're leaching small amounts of BPA out of them. … Even the low levels of BPA that leach from consumer plastics, canned food linings or other consumer goods … have been shown to be associated with harm, and people certainly should care about it.”
Yes, all Tupperware® plastics have been made 100% BPA free since 2010. Products are safe for consumers and for the environment.
However, Tupperware products aren't made from bisphenols. Most new Tupperware products are made from polypropylene (PP) or low density polyethylene (LDPE). According to Ecowatch, poplypropylene is a relatively good material for food storage as it has a high heat tolerance and doesn't leach so many chemicals.
There's no standard rule of thumb about when it's time to throw out your plastic containers. How long your containers last depends on how well you care for them, and the quality of plastic they're made of. You'll know it's time to toss your containers if they become warped or cracked.
BPA, as well as arsenic, lead, cadmium, and mercury, are dangerous substances for humans, so if you've been using vintage Tupperware, the best thing you can do is not use them anymore.
If your plastic containers are at the point of no return—say, if they're cracked, you can't handle the stench, or you're missing pieces—then it may be time to say goodbye. DeLeonibus says you can easily recycle most plastics according to the recycling symbol on the bottom of the container.

Use a Desiccant
Desiccants like silica gel are another way to help prevent condensation in shipping containers. They absorb moisture in the air and help keep the container dry. Besides silica gel, calcium sulfate, charcoal, and calcium chloride can all function as desiccants.
Potential: Tupperware keeps refrigerated meat fresh for four to five days and from 6-12 months in the freezer. Tupperware preserves fruits and vegetables for five to six days, with baked goods staying fresh longer than the typical three days.
That said, plastic doesn't have the longevity offered by glass and stainless steel, so it's important to know when to swap out your container collection. “Plastic food storage containers should be replaced every six months to one year, depending on usage and wear and tear.
According to the U.S. Food and Drug Administration, non-food grade plastic containers may contaminate food. Plastic food containers must follow specific regulations to make sure they are safe for food. Use single-use containers once. Plastics designed for single use should be used only once.
Tupperware warrants that Tupperware® brand products that are subject to the “Limited Lifetime Warranty” will not chip, crack, break or peel (as such terms are defined in the “What's Covered” section of this policy), when used under normal, non-commercial use, for the lifetime of the product.
It turns out that all plastic food containers leach toxic chemicals and are a threat to a healthy body. Safe plastic doesn't exist. It requires chemical bonds to make and shape plastics, and they can leach into food and beverages, especially when heated.
Is old Tupperware safe? What is not said in this statement but is implied is that at least some of Tupperware products sold prior to 2010 did in fact contain BPA. For consumers who want to be absolutely certain they have removed all known BPA sources, old Tupperware products manufactured prior to 2010 would be suspect.
Tupperware also chalked up lower sales and operating margins as primary reasons for the decline. In its hunt for additional funding, the company said it is reviewing various aspects of the business from its real estate portfolio to cash management and possible layoffs.
Plastic food storage containers and lids-such as Tupperware containers-that have the 1 or 2 recycling symbol on the bottom are accepted in almost all local recycling programs, provided they are empty, clean and dry. Recycle with the lid attached. Most recycling programs also accept #5 plastics.
Should I wash new plastic food containers before using them? It's unlikely that plastic food containers will be sterilised before they are packaged, so you should always wash new products to be safe. See our advice on hand-washing or putting them in the dishwasher.
According to Hunker, Tupperware and other reusable plastic containers hold onto smells because they are made from polypropylene, a porous type of plastic.
For other families, nothing was more exciting than a trip to the department store to purchase new Tupperware. One expert is now calling on people to stop using their vintage Tupperware immediately after she discovered measuring cups from 1972 actually contained lead an even arsenic.
Is glass Tupperware better than plastic Tupperware? Although glass Tupperware is heavier and easier to break, overall it is the better choice. By using glass Tupperware, you can be certain that your food will not be contaminated by harmful chemicals. Glass is natural, sustainable, and recyclable.
