Examples include soda and water bottles, medicine containers, and many other common consumer product containers. Plastic, polymeric material that has the capability of being molded or shaped. • HOMOGENEOUS PLASTICS : This variety of plastic contains carbon chain ie, the plastics of this group are composed of carbon atoms only and they exhibit homogeneous structure. Even though there's all this variety, plastic manufacturers still group plastics into two basic classes. Wow that was easy – Class III Commodities across the board. Of course, there are many differences in the plastics classified as miscellaneous by recycling programs. • HOMOGENEOUS PLASTICS : This variety of plastic contains carbon chain ie, the plastics of this group are composed of carbon atoms only and they exhibit homogeneous structure.
