Compared to Plastic

Stainless Steel vs. Plastic

    • Plastic can leach harmful chemicals into the bottle contents when heated including BPA, PVC and Phthalates
    • Plastics can stain, which means colored foods/liquids are getting into the plastic – our question is, “What’s getting out?”
    • Plastic easily scratches allowing for potentially harmful bacteria to build up
    • Plastic bottles typically need to be replaced after a few months of use

Bisphenol A

Bisphenol A or BPA is a compound used in many polymer based plastics like Polycarbonate Plastic (Shatter-proof clear plastic). This plastic is used to make baby bottles. BPA is used to strengthen and make plastics more flexible. Plastic without BPA is more fragile. In the body, BPA acts as an estrogen receptor agonist, which leads it to behave in a similar way to human estrogen.  BPA has been linked to cancer, fertility issues, attention difficulties and cardiac problems.

Many studies have indicated that there are concerns about BPA’s effects on infant and fetal development. In April 2008, the Canadian Government listed BPA as toxic and banned the use of polycarbonate plastic in baby bottles and infant formula can linings.

A number of US States are looking into banning BPA in baby products.

“We believe that the current safety margin (for BPA) needs to be higher. We have concluded that it is better to be safe than sorry.” Canadian Health Minister Tony Clement , April 19, 2008


PVC or Polyvinyl Chloride is used to make vinyl polymers and is used to soften plastics, and increase flexibility. It is commonly used in a variety of plastic products and piping. It is considered to be a carcinogen and can leach Lead and Phthalates.


Phthalates are used to make plastic more flexible, durable and longer lasting. Phthalates are easily released as plastic ages. They have been linked to Asthma, Metabolic Disorders, Attention Deficit Disorder and interfere in hormone production.
