How to Decode the Tupperware Symbols on Every Product

♻️ 5. Recycling Symbol (Resin Identification Code)

What it looks like: A triangle made of arrows, with a number (1–7) inside.

✅ Meaning: The number tells you what kind of plastic the product is made of:

• #1 PET: Single-use bottles
• #2 HDPE: Milk jugs, sturdy plastics
• #5 PP (Polypropylene): Most Tupperware — durable, heat-resistant, and microwave-safe
• #7 Other: Mixed plastics; some may not be food-safe

🌍 Tip: This symbol is for recycling centers — not for telling you whether a container is food-safe. But #5 is your best bet for reusable, food-safe containers.

🚫 6. Not Safe for… Symbols

What they look like: Any of the above symbols with a slash (⛔) through them.

⚠️ Meaning: Avoid that activity — e.g., microwave, dishwasher, freezer — as it could damage the container or release harmful substances.

💧 7. Leak-Proof / Liquid-Safe Symbol

What it looks like: Sometimes shown as a droplet or liquid with a seal.

✅ Meaning: Designed to hold liquids without leaking.
💡 Note: Not all lids are equal — always test with water before trusting it in a bag or lunchbox.

🧾 Final Thoughts

Understanding these symbols means fewer ruined containers, better food safety, and a longer life for your Tupperware. It only takes a minute to flip your container over and check — but it could save you from stained plastics, warped lids, or microwave mishaps.

So next time you’re meal prepping, freezing leftovers, or packing lunch, take a quick glance at the bottom. Your Tupperware is trying to tell you something — now you know how to listen.
