Sustainability is something we’re passionate about, so we’d love it if you could recycle our packaging after use! The box is cardboard and can be recycled along with the plastic trays and seal (Our trays are Recyclable #5PP (polypropylene), Films are Recyclable #7, and Gel packs are Recyclable #4). For the ice gel packs, please follow the manufacturer's instructions on the outside of the gel pack. The padding/insulation is biodegradable. Learn more about our journey towards sustainability!
