We live in a world that values its plastic products. Plastic, and all of its variations, is one of the materials that makes modern life possible. Plastic packaging is actually good for the environment because it can be recycled and, when used for food storage, keeps food out of landfills where it takes up valuable real estate and contributes to global warming. One process to make various plastic products is rotational molding. With this method, small items like ping pong balls are possible. Medium size items like laundry trucks are possible. Even bigger things like tanks that can hold as much 20,000 gallons can be made with rotational molding techniques.
