The BPA-Free Promise: Understanding Rubbermaid's Claims
For many years, the primary concern surrounding plastic food storage was the chemical Bisphenol A (BPA), an endocrine disruptor. In response to consumer demand, Rubbermaid introduced new product lines, such as EasyFindLids and Brilliance, with clear labeling indicating they are BPA-free. The Brilliance line, for example, is made from Tritan plastic, a material often praised for its clarity, durability, and safety profile.
While the elimination of BPA is a significant step forward, it does not address all potential concerns regarding plastic. The term “BPA-free” simply means that BPA was not used in the product's manufacturing. However, other chemicals may be present, and the long-term effects of many plastic components are still under scientific scrutiny. For everyday meal prep, using BPA-free containers is still a preferable choice over older, polycarbonate plastics that contained BPA.
The Microplastics Controversy and Recent Lawsuits
Despite the BPA-free assurances, new and more complex safety issues have emerged, namely the potential for microplastics and nanoplastics to leach into food. These are microscopic plastic particles shed from containers, particularly when subjected to stress, such as heating or freezing.
In May 2025, a class-action lawsuit was filed against Newell Brands, the parent company of Rubbermaid. The lawsuit alleges that certain products, specifically from the "TakeAlongs" line, release microplastics when microwaved or frozen, despite being marketed as safe for these purposes. The complaint argues that these containers, made from polypropylene (PP) plastic, mislead consumers about their true safety, especially for vulnerable populations like children.
How plastic degrades
- Heat: Microwaving can cause plastic to break down faster, increasing the rate at which microplastics and other chemicals are released. High-sugar or high-fat foods intensify this effect.
- Cold: Freezing can make plastic brittle, leading to small cracks and fractures that can cause microplastics to break off and contaminate food.
- Damage: Scratches from utensils, abrasive cleaning, or regular wear and tear can create fissures where plastic can more easily break down.
Comparison Table: Plastic vs. Alternative Containers
| Feature | Plastic (e.g., Rubbermaid BPA-Free) | Glass | Stainless Steel |
|---|---|---|---|
| Microwave Use | Generally safe for reheating (with lid vented). Risk of microplastic leaching increases with high heat and fatty foods. | Safe for microwave heating. No risk of chemical leaching. | Never safe for microwave use; metal can cause arcing and damage. |
| Freezer Use | Most newer lines are freezer-safe, but freezing and reheating can lead to microplastic shedding. | Freezer-safe, but avoid extreme temperature changes (freezer to hot oven) to prevent shattering. | Freezer-safe; extremely durable with no leaching risk. |
| Chemical Leaching | Modern BPA-free plastics are less concerning but still subject to debate regarding other chemicals and microplastics. | Non-reactive and does not leach any chemicals into food. | Non-reactive and does not leach chemicals; safe for all food types. |
| Dishwasher Safe | Top-rack dishwasher safe for most lines; however, repeated high-heat washing can degrade plastic. | Fully dishwasher safe and durable. | Fully dishwasher safe and durable. |
| Durability | Lighter and more portable than glass, but can scratch, warp, and crack over time. | Durable and long-lasting, but can break if dropped. | Exceptionally durable and impact-resistant. |
| Visibility | Clear plastic (like Tritan) offers excellent visibility. | Clear glass offers perfect visibility. | Opaque; contents are not visible unless opened. |
Best Practices for Safe Container Use
To minimize risks and prolong the life of your meal prep containers, following best practices is essential, regardless of the material.
Follow Manufacturer Instructions
Rubbermaid's instructions are specific to their product lines. For microwaving, they advise using the base only for reheating and often recommend venting or removing the lid entirely. Exceeding the stated temperature guidelines or using containers in a conventional oven can cause melting or chemical release.
Use Caution with Microwaving
Given the microplastics concerns highlighted by recent lawsuits and research, many experts now advise against microwaving any plastic container, even if labeled “microwave-safe”. Instead, transfer food to a microwave-safe ceramic or glass dish for reheating. If you must use a plastic container, do so for minimal time and only for reheating, not cooking, and always ensure the lid is vented.
Replace Damaged Containers Promptly
Old, scratched, or cloudy plastic containers are more susceptible to leaching chemicals and shedding microplastics. As soon as you notice any signs of wear and tear, it's time to replace them. This is especially important for containers that have been heavily used or exposed to a lot of heat or cold.
Handle with Care
For long-term use, wash plastic containers on the top rack of the dishwasher or, preferably, hand-wash them with non-abrasive cleaners. Avoid using sharp utensils that can scratch the container's surface. Allow both food and containers to cool before sealing and refrigerating to reduce stress on the plastic.
Conclusion: Navigating the Safety of Rubbermaid Containers
The question of whether Rubbermaid meal prep containers are safe is complex. Modern versions are BPA-free and are generally considered safe for cold storage and short-term, low-heat reheating, provided they are in good condition and used according to instructions. However, recent lawsuits and scientific research have introduced new concerns about microplastic contamination, particularly with microwaving and freezing. For those who want to completely avoid these potential risks, opting for alternatives like glass or stainless steel is the safest choice. For plastic users, minimizing microwave use, replacing damaged containers, and following care instructions are critical steps to maximize safety.
