Are your lunch boxes plastic and BPA free?
Stainless steel lunch boxes from Sattvii are completely free of BPA and plastic. Our stainless steel lunch boxes consciously rely on vapor-free and odorless seals made of silicone free of petroleum and plastic. What many people don't know is that although silicone is a plastic, it is made from silicon, a semi-metal.
Silicone is therefore a plastic, but it is non-toxic and degrades much more quickly than plastics made of plastic. For more information on the subject of silicone seals, we recommend our article: Silicone - the plastic-free seal .
