The Kid Kanteen — a reusable, lightweight, and risk free 40 oz stainless steel bottle designed for small hands comes with a loop or sport cap made from safe, non leaching polypropylene plastic (pp#5).
Klean kanteens products are a wonderful alternative to the every day plastic bottles that many of us drink from. Made of stainless steel, they are a healthier choice to plastic bottles due to the lack of BPA and other toxins found in most plastics. Also, because they are reusable and in turn reduce plastic production Klean Kanteens are considered environmentally friendly
Klean Kanteens are made from #304 stainless steel, the material of choice in the food processing, dairy, and brewery industries. Stainless steel is easy to clean, durable, inert, sanitary, and non-leaching.
The plastic tops found on the Klean Kanteen Bottles are Polyproplene #5. This type of plastic is non leaching and therefore provide a safer alternative from top to bottom.
Aside from the obvious uses as an every day water bottle (the 12oz Klean Kanteen with sport top being perfect for purses) and childrens sippy cups, they are starting to to show up as milk and juice containers in the fridge. The 40oz Klean Kanteen is the most popular method for this purpose.
