While many theories suggest that plastic containers or bins are not good, it is not always true. As long as the material used in making the bins has been approved by the United States FDA, it is completely safe for storing food items. The Pureness Pet Food Container, for example, is made from the FDA-approved Polypropylene (PP). This material does not pose any sort of health risk and is safe for dog food storage. Plastic bins can keep food fresh and away from pests. Whenever your dog needs to eat, you can simply pour the food from the container directly on your dog’s bowl.
