Some products do have plastic BPA-free plastic in their make-up for accents or structure, but still provide a stainless steel or silicone part on the inside of the lid so that food and drink don’t actually touch plastic, creating an all stainless interior. Lunchbots thermals, Klean Kanteen TK Wide Bottles with the TK Wide Loop Lid and Beautiful Beaches glass bottles are among the products that are made this way.
