Polypropylene (PP) and Misconceptions About BPA and Chemicals

  • Date : 05/10/2025

Polypropylene (PP) is one of the most widely used plastics for food, beverage, and consumer goods packaging. It is valued for its key properties such as being lightweight, heat-resistant, and recyclable, making it a popular choice for Food Contact Materials (FCMs) . However, there are several misconceptions regarding BPA (Bisphenol A) and other chemicals that may cause unnecessary concern among consumers.

What is BPA and Which Plastics Contain It?

  • BPA is a chemical commonly used in the production of polycarbonate (PC) plastics and epoxy resins.
  • BPA is not used in the production of polypropylene (PP).
  • Therefore, PP packaging is BPA-free, even though some consumers mistakenly believe that PP contains BPA.

Common Misconceptions About Chemicals in PP

  • 1. “PP releases harmful chemicals when heated”
    • Truth: Food Grade PP has been tested under EU Regulations, FDA standards, and Thai TIS standards to withstand heat without releasing harmful chemicals beyond safe limits.
    • Using PP containers in microwaves or with hot foods according to instructions is safe.
  • 2. “PP is unsafe for hot or fatty foods”
    • Truth: PP is more resistant to heat and fats compared to PET or PE.
    • It is suitable for hot meals, fried foods, and hot beverages.
  • 3. “PP cannot be recycled”
    • Truth: PP is Plastic #5 and can be recycled if properly sorted and processed.

Advantages of PP in Terms of Safety

  • 1. Food Grade and BPA-Free
    • Safe for food and beverage applications.
    • Certified under international standards (EU, FDA, JHOSPA) and Thai TIS standards (435, 655, 2442).
  • 2. Durability and Flexibility
    • High heat resistance and impact strength.
    • Easily molded into various shapes to meet diverse packaging requirements.
  • 3. Reusable and Recyclable
    • Consumers can reuse PP containers multiple times.
    • Supports circular economy initiatives and reduces single-use plastic waste.

How to Communicate Correctly to Consumers

  • Clear labeling such as “PP Food Grade,” “BPA-Free,” and “Microwave Safe.”
  • Provide information via online channels or QR codes to build trust.
  • Educate consumers about different plastic types and clarify distinctions between PP, PC, and PET.

Conclusion

Polypropylene (PP) is a safe and reliable plastic for food and beverage packaging. Misconceptions about BPA and other chemicals can create unnecessary concern, but proper education and transparent communication can reassure consumers. PP = BPA-Free, Food Grade, Safe & Recyclable
