TRIPLE LAYER DESIGN - Our bags feature a sturdy thermal aluminum outer layer, an inner EPE (eco-friendly plastic) waterproof layer, and a final inner PE nontoxic film layer. Most other bags are single-layer and aren't efficient at maintaining internal temperatures or will start to leak moisture. QUALITY has NEVER BEEN COMPROMISED: Built to last made of strong and thick aluminum foil bags are BPA-free and safely printed with green leaf patterns which are water-based and non-toxic.
