Microplastics are tiny plastic particles less than 5mm in size that can enter the environment and food chain, posing risks to ecosystems and human health. Tupperware is a popular brand of plastic food storage containers that may release microplastics into stored food as the containers age, undergo heating/cooling cycles, or get exposed to certain chemicals.

How Tiny Plastic Bits Get into Food
- As plastic containers age and get reused, the plastic can break down and shed tiny particles into stored food
- Plastic additives and chemicals from manufacturing can leach into food/drinks
- Even new containers may release plastic bits from production residue or atmospheric exposure
Factors Affecting Plastic Bit Release
| Factor | Explanation |
|---|---|
| Age and Condition | Older, well-used containers release more plastic bits |
| Plastic Type | Some plastics like PP and PE are more resistant than others |
| Temperature Exposure | High heat from microwaving or hot foods speeds up breakdown |
| Surface Damage | Scratches and cracks create sites for plastic shedding |
| Chemical Exposure | Certain chemicals and acidic foods increase plastic release |
Potential Health Risks
- Plastic bits can accumulate in the body, causing inflammation and oxidative stress
- May contain toxic additives or absorb environmental pollutants
- Can interfere with nutrient absorption, immune function, and reproductive health
- Act as carriers for other harmful chemicals into the body
Safer Storage Options
| Option | Pros | Cons |
|---|---|---|
| Glass | Non-toxic, microwave/dishwasher safe, durable, recyclable | Can break, heavier than plastic |
| Stainless Steel | Non-reactive, durable, lightweight, recyclable | Not microwave-safe, more expensive |
| Silicone | Flexible, microwave/dishwasher safe, BPA-free | Less eco-friendly, may not be as durable |
| Ceramic/Porcelain | Non-toxic, microwave/dishwasher safe, durable | Can break, heavier than plastic |
Proper Disposal and Recycling
- Recycle plastic containers whenever possible
- Avoid burning or littering, as it releases microplastics and pollutants
- Support initiatives to reduce plastic waste and promote sustainable packaging
The Problem: Plastic Containers and Tiny Plastic Bits
How Tiny Plastic Bits Get into Containers
Tiny plastic bits can find their way into plastic food containers through various paths. As these containers age and undergo repeated use, heating, and exposure to chemicals, the plastic material can break down and shed tiny particles. This process speeds up due to factors like heat, light, and chemical exposure, causing the container's surface to flake or shed tiny plastic bits.
Additionally, plastic additives and chemicals used in the manufacturing process can leach out of the container and into the stored food or drinks, contributing to tiny plastic bit contamination. Even brand-new containers may release tiny plastic bits due to leftover particles from the production process or atmospheric exposure during transportation and storage.
Factors Affecting Tiny Plastic Bit Release
Several key factors influence the rate and extent of tiny plastic bit release from plastic food containers:
-
Age and Condition: Older, well-used containers are more likely to release higher levels of tiny plastic bits due to material breakdown over time.
-
Plastic Type: Different plastic polymers, such as polypropylene (PP) and polyethylene (PE), have varying degrees of resistance to breakdown and tiny plastic bit shedding.
-
Temperature Exposure: Exposure to high temperatures, such as microwaving or storing hot foods, can speed up the breakdown of plastic materials and increase tiny plastic bit release.
-
Surface Damage: Scratches, cracks, or other surface imperfections on the container can create sites for tiny plastic bit generation and shedding.
-
Chemical Exposure: Certain chemicals, detergents, or acidic foods can interact with the plastic material, leading to increased tiny plastic bit release.
Potential Health Risks
The ingestion of tiny plastic bits from contaminated food or drinks stored in plastic containers raises concerns about potential health risks. While research is ongoing, some potential risks associated with tiny plastic bit exposure include:
| Risk | Explanation |
|---|---|
| Accumulation in the Body | Tiny plastic bits can accumulate in various organs and tissues, potentially causing inflammation, oxidative stress, and other adverse effects. |
| Toxicity | Some tiny plastic bits may contain harmful additives or absorb toxic chemicals from the environment, which could be released in the body upon ingestion. |
| Disruption of Biological Processes | Tiny plastic bits may interfere with normal physiological processes, such as nutrient absorption, immune function, and reproductive health. |
| Chemical Absorption | Tiny plastic bits can act as carriers for other environmental pollutants, facilitating the absorption and accumulation of harmful chemicals in the body. |
While the full extent of the health risks is still being investigated, minimizing exposure to tiny plastic bits from plastic food containers is a wise precautionary measure.

Simple Ways to Reduce Tiny Plastic Bits
Using Plastic Containers Safely
To cut down on tiny plastic bits from food containers, follow these tips:
1. Avoid Heating Plastic
Never microwave food or drinks in plastic containers, even if labeled "microwave-safe." The high heat can cause the plastic to break down and release tiny bits into your food.
2. Replace Old or Damaged Containers
Throw away any plastic containers that are scratched, cracked, or worn out. These flaws can speed up the shedding of tiny plastic bits.
3. Follow Cleaning Instructions
Check the manufacturer's instructions for proper cleaning methods. Some plastic containers may not be dishwasher-safe, as the high heat and harsh detergents can degrade the plastic over time.
4. Limit Reuse
While reusing plastic containers reduces waste, it's best to replace them after a reasonable amount of time, as repeated use can lead to tiny plastic bit release.
Better Storage Options
Consider switching to safer alternatives for food storage:
| Option | Pros | Cons |
|---|---|---|
| Glass | - Non-toxic material - Microwave and dishwasher safe - Durable and long-lasting - Easily recyclable |
- Can break - Heavier than plastic |
| Stainless Steel | - Non-reactive - Durable and long-lasting - Lightweight and portable - Easily recyclable |
- Not microwave-safe - More expensive than plastic |
| Silicone | - Flexible and durable - Microwave and dishwasher safe - Non-toxic and BPA-free |
- Not as eco-friendly as glass or stainless steel - May not be as durable as claimed |
| Ceramic/Porcelain | - Non-toxic - Microwave and dishwasher safe - Durable and long-lasting |
- Can break - Heavier than plastic |
When choosing alternatives, think about durability, ease of use, and environmental impact to find the best fit for your needs.
Proper Disposal and Recycling
As plastic containers reach the end of their lifespan, it's crucial to dispose of them properly:
- Recycle whenever possible. Check with your local recycling program to ensure they accept the specific type of plastic.
- Avoid Burning or Littering plastic containers, as this can release tiny plastic bits and other harmful pollutants into the environment.
- Support Initiatives that aim to reduce plastic waste and promote sustainable alternatives, such as plastic bag bans or container deposit programs.
Final Thoughts
Tiny Plastic Bits: A Growing Worry
Tiny plastic bits from food containers are a rising concern. These small particles can end up in our food and environment. This happens when plastic containers get old, go through heating and cooling, or get exposed to certain chemicals.
