Are number 7 plastics safe? The safety of number 7 plastics, categorized as "other" in recycling codes, varies depending on their composition. While some are safe, others may contain harmful chemicals like BPA, making it crucial to understand the specific type of plastic you are using.
What Are Number 7 Plastics?
Number 7 plastics are a diverse category that encompasses various types of plastics not included in the first six recycling codes. This category includes newer, innovative plastics and older, potentially harmful ones. Common types of number 7 plastics include polycarbonate, polylactic acid (PLA), and other resins. These plastics are often found in food containers, water bottles, and packaging materials.
Types of Number 7 Plastics
- Polycarbonate: Known for its strength and clarity, often used in reusable water bottles and food containers. However, it may contain Bisphenol A (BPA), a chemical linked to health concerns.
- Polylactic Acid (PLA): A biodegradable plastic derived from renewable resources like corn starch, commonly used in eco-friendly packaging.
- Other Resins: This includes a variety of other plastics, each with unique properties and potential safety concerns.
Are Number 7 Plastics Safe for Food Storage?
The safety of number 7 plastics largely depends on their specific chemical composition. Some, like PLA, are considered safe and environmentally friendly. Others, such as polycarbonate, may leach harmful chemicals like BPA, especially when exposed to heat or acidic foods.
Key Considerations for Food Safety
- Check for BPA-Free Labels: If using number 7 plastics for food storage, look for products labeled as BPA-free to minimize exposure to this chemical.
- Avoid Microwaving: Heat can cause certain plastics to break down and release harmful substances. It’s best to avoid microwaving food in number 7 plastic containers unless they are specifically labeled as microwave-safe.
- Consider Alternatives: When possible, opt for safer alternatives like glass or stainless steel for food storage, especially for hot or acidic foods.
How Does BPA Affect Health?
Bisphenol A (BPA) is a chemical found in some number 7 plastics, particularly polycarbonate. It is an endocrine disruptor that can mimic estrogen in the body, potentially leading to various health issues.
Health Risks Associated with BPA
- Hormonal Disruption: BPA can interfere with the body’s endocrine system, potentially affecting reproductive health and development.
- Increased Risk of Chronic Diseases: Studies have linked BPA exposure to an increased risk of conditions like heart disease, diabetes, and obesity.
- Developmental Concerns: BPA exposure during pregnancy and early childhood may impact brain development and behavior.
How to Identify Safe Plastics
Understanding recycling codes and labels can help you make informed decisions about plastic use.
Tips for Identifying Safe Plastics
- Look for Recycling Codes: Plastics labeled with recycling codes 1, 2, 4, and 5 are generally considered safer for food contact.
- Check for BPA-Free Labels: Choose products explicitly labeled as BPA-free to avoid potential exposure.
- Research Brand Reputation: Opt for products from reputable brands known for prioritizing safety and transparency.

What Are the Alternatives to Number 7 Plastics?
Alternatives include glass, stainless steel, and BPA-free plastics with recycling codes 1, 2, 4, and 5. These materials are generally safer for food storage and have less environmental impact.
How Can I Reduce Plastic Exposure?
To reduce exposure, minimize the use of plastics, especially for food storage. Use alternatives like glass or stainless steel, avoid heating food in plastic containers, and choose BPA-free products.
Is PLA Plastic Safe?
PLA, a type of number 7 plastic, is considered safe and environmentally friendly. It is biodegradable and made from renewable resources, making it a popular choice for eco-conscious consumers.
Can Number 7 Plastics Be Recycled?
Recycling number 7 plastics can be challenging due to their diverse nature. Check with local recycling programs to see if they accept these plastics, and consider alternatives when possible.
How Can I Tell if a Product Contains BPA?
Look for products labeled as BPA-free. If this information is not available, contact the manufacturer for details. Choosing products from brands with a commitment to transparency can also help ensure safety.
Conclusion
The safety of number 7 plastics depends on their specific composition. While some, like PLA, are safe and eco-friendly, others may pose health risks due to chemicals like BPA. To ensure safety, opt for BPA-free products, use alternatives like glass or stainless steel, and stay informed about the materials in everyday items. By making conscious choices, you can reduce potential health risks and contribute to a healthier environment.
