SUMMARY

The hydration bladder discussed is manufactured by Guangzhou KMS and is made from TPU (Thermoplastic Polyurethane) and EVA (Ethylene Vinyl Acetate). The packaging does not explicitly state that the product is BPA-free, which raises concerns among consumers. While many products now highlight their BPA-free status, the absence of such labeling on this bladder leaves uncertainty regarding its safety. Further investigation into the materials TPU and EVA is necessary to determine their association with BPA.

PREREQUISITES
  • Understanding of material safety standards, specifically regarding BPA.
  • Knowledge of thermoplastic materials, particularly TPU and EVA.
  • Familiarity with product labeling regulations.
  • Basic research skills to evaluate product safety claims.
NEXT STEPS
  • Research the chemical properties and safety profiles of TPU and EVA.
  • Investigate regulations regarding BPA labeling in consumer products.
  • Explore alternative hydration bladder materials that are confirmed BPA-free.
  • Learn about consumer safety organizations that evaluate and certify product materials.
USEFUL FOR

This discussion is beneficial for consumers concerned about product safety, manufacturers of hydration products, and anyone interested in the implications of material choices in consumer goods.

I was just given a hydration bladder:

https://www.amazon.com/dp/B00JY9WFO2/?tag=pfamazon01-20

But NOWHERE on the package does it say it is BPA free. Almost every product now says it is BPA (Including glass jars which I find to be redundant.) free. Another website says it is made out of TPU and EVA. I don't know much about this stuff. I thought that perhaps you guys might know something.

Thank you!

What about a stamp on the bladder itself?

All there is on the bladder itself are; a measurement line on the side to tell me how much water is in the bladder, and various pictures under the forward slash symbol to tell me what I can't put in it. Do you know anything about TPU and/or EVA?

No. I was looking around, but nothing definitive. Some have it, some don't.
