Thank you for contacting Sterilite. We apologize for not responding sooner.
All of our storage products are made of polypropylene plastic,which is deemed a food safe material. The polypropylene used in our containers meets FDA requirements in the Code of Federal Regulations for all food contact excluding actual cooking applications. We do not use Latex, Teflon, or other stain resistant chemicals in our manufacturing process.
Once the plastic has cooled after molding, it will not break down or secrete anything into its contents. Many people, including wine makers, use our products for this purpose. We hope this is helpful and please let us know should you require other assistance.
