What Is Polyethylene-Terephthalate (PET) & Is It Safe?

 

 

Polyethylene-Terephthalate (PET) is a strong, light plastic commonly used to make packaging. More than half of the world’s synthetic fibers are made from PET and almost the majority of global bottle production is attributed to PET. It is often cited as an alternative to BPA but it still poses many negative health concerns. 

 

 

What Products Have PET In Them?

PET can be found in:

  • Packaging

  • Fabrics

  • Electronics

  • Containers

  • Cosmetics 

Is PET Safe?

Due to the fact that PET can leach harmful chemicals, PET is not safe and we list it as one of the chemicals to avoid.  

Health Impacts of PET Products

PET under greater than average conditions has been associated with the leaching of phthalates [1]. Leaching is the leaking of chemicals from a source - in this case, plastic - into the contents of said source, such as food. Phthalates are linked with negative effects such as endocrine and reproductive disregulation, early puberty, endometriosis, and infertility [2]. PET also is known for its rigidity and does not degrade easily, making it an environmental burden. 

Recommended Alternatives to PET

Safer alternatives to PET include plastic-free products such as glass, stainless steel, and wood. 

How to Avoid PET

Reduce your exposure to PET by: 

  • Using less plastic products and packaging

  • Buying fresh produce

  • Using your own reusable bags when shopping

  • Not using single-use plastic such as cutlery and bags

  • Using biodegradable wipes 

  • Looking for products with packaging other than plastic such as bamboo

Purchase our test kit and learn about your harmful chemical exposures.
