NO health-compromising chemicals or compounds used. Everything about our bags is completely safe, no BPA, PVC, or Phthalates. Our bags are made from an innovative blend of recycled and controlled-life plastic material that is carefully developed to achieve a superior litter and housekeeping experience. These 300 Green N Pack pet waste bags are conveniently packaged on a single roll in a box made from recycled content that dispenses one bag at a time. These bags are designed to hold medium to large size poop and fit perfectly in your pantry. Thick enough to withstand the rigors of shipping, warehouse storage, exposure to various environmental elements, and to get the pickup job complete, yet not too big or thick that just adds unnecessary costs or material to the waste stream.
