Are PET Containers Food Safe?

Published in Food Safety 2 mins read

Yes, Polyethylene Terephthalate (PET) containers are generally considered food safe.

PET is a plastic resin and a form of polyester. It's commonly used in the production of beverage bottles, food jars, and containers for a wide variety of products. The FDA has approved both virgin and recycled PET for food contact applications, making it a safe choice when properly processed and used.

Key Considerations for PET Food Safety:

  • FDA Approval: The U.S. Food and Drug Administration (FDA) has evaluated PET and determined it to be safe for contact with food and beverages. This applies to both original (virgin) PET and recycled PET (rPET), provided the rPET meets specific purity standards.
  • Recycling: Recycled PET (rPET) is an environmentally friendly option, and its safety for food contact is well-established when produced through approved recycling processes.
  • Limited Reuse: While PET containers are considered safe for their intended use, repeated reuse (especially for hot liquids or washing in high temperatures) is not generally recommended. This is because repeated use can potentially lead to degradation of the plastic and the leaching of chemicals. Single use of beverage containers is advisable.
  • Temperature Sensitivity: PET is not suitable for very high temperatures. Avoid using PET containers in microwave ovens or dishwashers unless they are specifically labeled as safe for these applications.
  • Proper Processing: The safety of PET, particularly recycled PET, depends on proper processing and cleaning to remove any potential contaminants. Reputable manufacturers adhere to strict quality control standards.

Why PET is a Popular Choice for Food Packaging:

  • Lightweight and Durable: PET is a strong yet lightweight material, making it ideal for packaging and transporting food and beverages.
  • Recyclable: PET is one of the most widely recycled plastics, contributing to sustainability efforts.
  • Transparent: PET is naturally transparent, allowing consumers to see the contents of the container.
  • Barrier Properties: PET provides a good barrier against oxygen and carbon dioxide, helping to preserve the freshness and flavor of food and beverages.
