What is the bottle cap made of?Updated 6 months ago
Our caps are aluminum which contains a BPA-Free liner. It is an epoxy-based coating that uses zero BPA in its formulation. In addition, the coating has no styrene and complies with Prop 65 NSRL. The coating (liner) constitutes a very small percentage of the total bottle by weight which is driven off completely in the recycling process and does not affect the bottle’s recyclability.
