Disadvantages of Storing Food in Plastic Containers

Today, we're focusing on a topic that's both important and often overlooked - the disadvantages of storing food in plastic containers.

You might be wondering why this matters. Well, it turns out that using plastic containers for your food has several implications for your health and our environment.

So, let's delve into this topic and shed some light on why rethinking our use of plastic containers in the kitchen could be a smart move!

What this article covers:

This Is What Happens When You Eat From Plastic Containers

Are bento boxes healthy? They can be, depending on the material of the box. Eating from plastic containers can lead to the leaching of chemicals into your food.

Our research indicates that chemicals like BPA and phthalates, commonly found in plastics, can migrate into the food we eat, but more on this shortly.

In contrast, our two-layer stainless steel bento box offers a safer and more sustainable alternative. Made from premium 304 food-grade stainless steel, it's free from harmful BPA.

Our bento box comes in two sizes, each tailored to different needs. The regular size has a top half capacity of 540ml and a bottom half capacity of 800ml, summing up to a total capacity of 1340ml.

The large size, on the other hand, offers a top half capacity of 760ml and a bottom half capacity of 1200ml, with a total capacity of 1960ml.

What is a bento box, you ask? A nifty container used to store a variety of foods.

Reasons Not To Eat From Plastic Containers

Using plastic containers for food storage and consumption might seem convenient, but there are several compelling reasons to reconsider this practice.


Let's explore these reasons.

dangers of plastic containers for food

Chemical Leaching

Our findings show that one of the primary concerns with plastic containers is the leaching of chemicals into food. Harmful substances like BPA and phthalates can migrate from the plastic into the food and even more so when heated.

These substances have been linked to several health concerns, including metabolic disorders and reduced fertility. Based on our observations, the specific health risks include hormonal imbalances, as some chemicals in plastics can act as endocrine disruptors.

Additionally, there's a potential increased risk of chronic diseases such as obesity, diabetes, and even certain types of cancer. The extent of these risks often depends on factors like the type of plastic, the temperature of the food, and the duration of storage.

Environmental Impact

Plastic containers significantly contribute to environmental pollution. Most plastics are non-biodegradable, leading to long-term environmental damage.

The production and disposal of plastic containers add to the growing problem of plastic pollution, affecting wildlife and ecosystems.

Wear And Tear

Repeated use and cleaning of plastic containers can cause wear and tear, making them more susceptible to leaching chemicals. Washing them in dishwashers or using abrasive cleaning methods can degrade the plastic, increasing the risk of chemical migration into food.

Fatty Foods And Plastic

Storing fatty or oily foods in plastic is particularly risky. Many chemicals used in plastics are fat-soluble, making them more likely to leach into fatty foods. This increases the potential for harmful chemical intake.

Microplastics Concern

Microplastics, tiny plastic particles, can also migrate from containers into food. These particles pose a health risk as they may accumulate in the body, leading to inflammation and other health issues.

What Can I Do About It?

Choosing stainless steel containers as an alternative is a smart move. The robustness of stainless steel stands out, offering a long-lasting solution that resists wear and tear far better than plastic.

This durability not only makes it a cost-effective choice but also reduces waste, contributing to environmental sustainability.

The health benefits of stainless steel are significant. Unlike plastic, stainless steel is free from harmful chemicals like BPA and phthalates, which can leach into food and pose health risks.

This non-toxic quality of stainless steel ensures that your food remains safe and uncontaminated, whether stored at high or low temperatures.

Another benefit of stainless steel is its non-reactive nature. It won't absorb flavors or odors. This means you can store spicy foods, acidic fruits, or pungent items without any lingering smells or tastes.

To further support your shift away from plastic, consider our Stainless Steel Bento Box with Silicone Seal. This bento box features 5 compartments, making it perfect for portion control and keeping different foods separate.

The bento box features a removable silicone seal, which is key in maintaining the freshness of your food and preventing any leaks.

Constructed from 304 food-grade stainless steel, the bento box is not only durable but also safe for food storage.

For added convenience, the bento box is dishwasher safe. This feature ensures easy and efficient cleaning, saving you time and effort after each use.

In terms of size, the bento box measures 255mm x 188mm x 50mm. This compact size makes it easy to transport and store, while still providing ample space for a satisfying meal.

But what goes in a bento box? And are bento boxes eaten cold? A main, a few sides, and some filler veggies, and yes they are usually eaten once cooled.


It's become clear that the disadvantages of plastic containers extend far beyond mere convenience. The health risks associated with chemical leaching cause for concern.

These chemicals, known for disrupting hormonal balance, can lead to metabolic disorders and reduced fertility. The environmental impact is equally worrying, with the non-biodegradable nature of plastics contributing to long-term ecological damage.

As a proactive step, we at Activated Eco advocate for the switch to safer and more sustainable alternatives like our stainless steel bento boxes.
