How to Verify if Your Tupperware is BPA-Free: Tips and Concerns

Introduction

With growing concerns about the safety of plastic containers, particularly those containing Bisphenol A (BPA), it is important to determine if your Tupperware products are free of this chemical. This article provides a comprehensive guide on how to verify if your Tupperware is BPA-free, with a detailed discussion on the measures to take.

How to Determine if Your Tupperware is BPA-Free

Check for Labels: Look for labels or markings on the bottom of your Tupperware. Many products will state if they are BPA-free. However, not all containers with a recycling code 7 will contain BPA, so further verification is needed. Examine the Recycling Code: BPA is commonly found in plastics with recycling codes 3 (polyvinyl chloride) and 7 (other). However, it is crucial to note that not all plastics with the code 7 contain BPA, as this code can encompass a variety of plastic types. Consult the Manufacturer: For detailed information about the materials used, visit Tupperware's official website or contact their customer service. They often provide comprehensive details about the safety and composition of their products. Research the Product: If you have the product's name or model number, search online for specific safety information regarding that particular item. Manufacturer websites and safety organization reports can be valuable resources. Look for Certification: Some products may have certifications from safety organizations indicating they are free from harmful chemicals, including BPA. Such certifications can provide further reassurance.

Tupperware's Commitment to BPA-Free Products

Tupperware has been manufacturing BPA-free products since 2010. They use recycled plastic waste materials and refine them to their purest form, meeting all EPA and industry standards. For added assurance, it is recommended to request a certificate of analysis from the vendor. If the vendor asserts the plastic is BPA-free, ensure you receive an analytical report to back their claim.

Contamination Concerns and the Importance of Verification

Contamination from cross-over factors, foreign sources of air, and other foreign countries can introduce BPA into even BPA-free products. Therefore, it is crucial to verify the BPA content by requesting a certificate of analysis (C of A) or a letter of assurance from the vendor. This is especially important if you have a high level of concern, as a high level of trust without verification can be misleading.

BPA and Its Health Implications

Bisphenol A (BPA) is known for its potential endocrine-disrupting properties, imitating the effects of the hormone estrogen. Animal studies have linked BPA to changes in fetal/neonatal prostate glands and breast tissue, raising concerns about its impact on human health. While there is some controversy about the relevance of animal studies to humans, many scientists and consumers advocate for reducing exposure to BPA.

Understanding Endocrine Disrupters

Endocrine disrupters are synthetic substances that interfere with the body's natural hormones, such as estrogens, androgens (e.g., testosterone), thyroid hormone, and pancreatic hormones. When introduced into the body, BPA can be absorbed into the bloodstream and metabolized in the liver, potentially affecting various organs and tissues. Concerns arise from the potential for BPA to disrupt the body's ability to regulate metabolism, use insulin, and other hormonal functions.

Common Applications of BPA

Bisphenol A (BPA) has several industrial applications, including:

To harden plastics, common examples being polycarbonate drinking bottles, hard plastic baby bottles, and infant drinking cups. In the epoxy resin linings of cans for food and infant formula. In medical equipment, dental sealants, compact disks, and thermal paper used in sales receipts, fax paper, and lottery tickets.

Conclusion

While Tupperware's commitment to BPA-free products is commendable, it is essential to verify the safety of your products through the steps outlined in this article. By following these guidelines, you can ensure your Tupperware is safe for use and that you are safeguarding your health from potential endocrine disrupters.
