Decoding the Mystery Behind the Numbers on Tupperware

Tupperware, a household name in food storage, can sometimes seem like a puzzle with all its numbers and symbols. In this article, we will explore what those numbers on Tupperware mean and provide clarity on the types of plastic used and how they can be managed for proper recycling.

Understanding Plastic Recycling Codes on Tupperware

When you pick up a Tupperware container from the shelf, you may notice a small triangle on the bottom, containing arrows and a number from 1 to 7. This number is a plastic recycling code, indicating the specific type of plastic your container is made of. Understanding these codes is crucial for proper recycling and environmental awareness.

Plastic Recycling Codes Explained

While the triangle with the arrows is commonly recognized as a sign of recyclability, each number within the triangle tells a specific story about the type of plastic. Here’s what these numbers mean:

1 (PET or PETE)- Polyethylene Terephthalate (PET or PETE) is one of the most common types of plastic. It is often used in water bottles because it is lightweight, shatterproof, and easy to recycle. 2 (HDPE)- High-Density Polyethylene (HDPE) is another recyclable plastic used for soda bottles, milk jugs, and some types of Tupperware. It is durable and can withstand boiling water. 3 (V)- Not often encountered in the home, Polyvinyl Chloride (PVC) is not recyclable by most communities due to its potential to release harmful chemicals during the recycling process. 4 (LDPE)- Low-Density Polyethylene (LDPE) is used for sandwich bags, shrink wrap, and some types of Tupperware. It is typically recyclable but not as convenient as PET or HDPE. 5 (PP)- Polypropylene (PP) is another type of plastic used for yogurt containers and some types of Tupperware. It is microwave-safe and can withstand cold and hot temperatures. 6 (PS)- Polystyrene (PS) is commonly used for foam containers, take-out containers, and some types of Tupperware. It is not accepted by many recycling programs due to its limited recyclability. 7 (OTHER)- This includes a variety of plastics like polycarbonate (PC), acrylic, and polylactic acid (PLA). These plastics are not as common but should be checked and properly managed.

The Secret of the Numbers: What They Signify

Many Tupperware containers are marked with a series of numbers corresponding to their recycling code, followed by a hyphen and additional digits. This coding system is not for your convenience but rather it serves a specific purpose related to the manufacturing process of the product.

The first set of digits, often presented as “xyz,” may represent the type and size of the object, such as a particular bowl style with a specific diameter. For example, a series like 123- might indicate that the object is a small bowl. The “nm” section, which follows the hyphen, may indicate the color of the product. For instance, if the container is blue, the number 04 might follow the hyphen.

Proper Management of Tupperware

By understanding these codes, it is easier to manage your Tupperware effectively. For instance, knowing that a container with the recycling number 2 is recyclable in most areas can help you decide where and how to dispose of it.

Additionally, you can now make informed choices when purchasing new Tupperware. Products that have multiple recycling codes can be a red flag, indicating that they may be harder to recycle or not as environmentally friendly.

Remember, the key to successful recycling lies in knowing the codes and understanding what each number means. This not only helps the environment but also ensures that your Tupperware continues to serve you well, both in storage and meal preparation.

Conclusion

The numbers on Tupperware are not just a random arrangement of digits but a coded message that can help you make informed choices about how to handle your Tupperware. Whether it's recycling, reusing, or simply better understanding the product, these numbers play a significant role in the overall sustainability of your kitchen.
