...polystyrene packaging comes in two forms: foam and solid?
The most recognizable forms of polystyrene packaging are expanded and extruded foams (sometimes incorrectly called Styrofoam®, a Dow Chemical Co. trademarked form of polystyrene foam insulation). Foamed polystyrene is used to make cups, bowls, plates, trays, clamshell containers, meat trays and egg cartons as well as protective packaging for shipping electronics and other fragile items.
Solid polystyrene is used in products such as cutlery, yogurt and cottage cheese containers, cups, clear salad bar containers and video and audiocassette housings.
...many businesses and institutions depend on polystyrene packaging?
Schools, hospitals, nursing homes, supermarkets, restaurants and sports stadiums are among the many institutions and businesses that rely on polystyrene packaging. Its sturdy construction and sanitary design provide excellent insulation at an economical cost. Grocery stores use polystyrene in virtually all meat and poultry trays. In addition, polystyrene packaging can be found in egg cartons and a variety of produce packages, such as apple trays, mushroom tills, tomato containers, and strawberry and grape crates.
...polystyrene makes exceptional protective packaging?
Polystyrene protective packaging comes in two primary forms loose fill "peanuts" and shape molded packaging. Loose fill "peanuts" allow variously shaped items, such as office supplies or cosmetics, to be shipped in the same box. Shape molded packaging fits snugly around delicate products like computers, television sets, stereo equipment and appliances to protect them during shipping.
Both shape molding and loose fill are lighter in weight than other protective packaging, saving energy and money during shipment. They also resist moisture and do not attract rodents or insects. An added benefit, polystyrene protective packaging can be used over and over again through reuse and recycling.(1)
