It can have serious effects on the health of birds or marine animals that swallow significant quantities. Polystyrene foam EPS can be used in manufacture of sliders, model planes and even surfboards because of its positive strength to weight ratio. Polystyrene foodservice packaging typically insulates better, keeps food fresher longer and costs less than alternatives. It is an inexpensive resin per unit weight. All packaging – glass, aluminum, paper and plastics (such as polystyrene) – contains substances that can “migrate” in very tiny amounts to foods or beverages. [67] In 2013, San Jose became reportedly the largest city in the country to ban polystyrene foam food containers. [69] In 1988, the first U.S. ban of general polystyrene foam was enacted in Berkeley, California. Copolymers called ABS have similar properties and can be used at low temperatures, but they are opaque. Copolymers of styrene and acrylonitrile (SAN) are more resistant to thermal stress, heat and chemicals than homopolymers and are also transparent. [96] Styrene oligomers in polystyrene containers used for food packaging have been found to migrate into the food. Styrofoam boards are used for insulation in buildings, in roads, and by florists, to name a few. General-purpose polystyrene is clear, hard, and rather brittle. Polystyrene can be naturally transparent, but can be co… Public health officials encourage the use of sanitary, single-use foodservice packaging (such as polystyrene) in appropriate settings. Foam polystyrene can be more than 95 percent air and is widely used to make home and appliance insulation, lightweight protective packaging, surfboards, foodservice and food packaging, automobile parts, roadway and roadbank stabilization systems and more. supervisors OK toughest ban on foam packaging in U.S", "The Throwaway Generation: 25 Billion Styrofoam Cups a Year", "Maryland Foam Packaging Ban, Energy Bills to Become Law", "Statement: Maryland becomes the second state to ban plastic foam containers", "Maryland's new laws: banning foam food containers, raising tobacco-buying age, reforming UMMS board", "Even Paper Bags Will Be Banned From N.J. Supermarkets", "China moves to end its 'ban' on PS food packaging", "Expanded polystyrene (kaylite): What are its impacts? All food packaging – glass, aluminum, paper and plastics (such as polystyrene) – contains substances that can “migrate” in very tiny amounts to foods or beverages. [citation needed] It must be concealed behind drywall, sheet metal, or concrete. For this reason, it is great choice for signs and fabrication. EPS insulation material also has applications in horticulture in seedling trays to promote aeration of soil. It is used in particular for thermal insulation of houses and buildings. Hot foods stay hot, cold foods stay cold, and fresh foods stay fresh. Polystyrene can be solid or foamed. [93], Polystyrene is commonly used in containers for food and drinks. It’s easy to snap in half or crumble but, crucially, it’s strong in compression and therefore protects delicate objects if dropped or crushed. [82], The city of Vancouver, Canada, has announced its Zero Waste 2040 plan in 2018. FDA has for decades stated that polystyrene is safe for use in contact with food. PS-I (impact resistant polystyrene) consists of a continuous polystyrene matrix and a rubber phase dispersed therein. [80], The government of Zimbabwe, through its Environmental Management Agency (EMA), banned polystyrene containers (popularly called 'kaylite' in the country), under Statutory Instrument 84 of 2012 (Plastic Packaging and Plastic Bottles) (Amendment) Regulations, 2012 (No 1.) That’s one of the reasons why FDA regulates food packaging in the first place – to be confident that the amount of substances that might actually migrate is safe. From organic salads to spicy chili, polystyrene packaging offers more convenience and dining enjoyment for people on the go. Resin identificiation codes are used to identify plastics for recycling purposes. Some containers may be safely used in a microwave, but only if labeled as such. Refrigerators, air conditioners, ovens, microwaves, vacuum cleaners, blenders – these and other appliances often are made with polystyrene (solid and foam) because it is inert (doesn’t react with other materials), cost-effective and long-lasting. Styrene, a petroleum by-product, is the principle component of polystyrene. Polystyrene is the material of choice for packaging because it’s nice and light. The European Commission/European Food Safety Authority and other regulatory agencies have reached similar conclusions. Although the Styrofoam brand has become the common term for polystyrene, Styrofoam is mostly used as insulation rather than as craft material because it is a harder foam. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. [53] Unlike PS-I and SBC, it is not a thermoplastic, but an elastomer. [88][better source needed] According to the American Chemistry Council, when polystyrene is incinerated in modern facilities, the final volume is 1% of the starting volume; most of the polystyrene is converted into carbon dioxide, water vapor, and heat. [52]:476, SBS (styrene-butadiene-styrene block copolymer) is made by anionic block copolymerization and consists of three blocks:[54], SSSSSSS­SSSSSSS­SSSSSSBBBBBBB­BBBBBBB­BBBBBBSSSSSSS­SSSSSSS­SSSSSS. Effects generally take hours to days. [70] In San Francisco, supervisors approved the toughest ban on "Styrofoam" (EPS) in the US which went into effect January 1, 2017.
