Food and pharmaceutical grades of calcium carbonate are covered by the Food Chemicals Codex (7) and the United States Pharmacopeia (8) and subject to U.S. Food and Dmg Administration Good Manufacturing Practices (9). Both purity requirements and test methods are available (7,8). Calcium carbonate is listed in the U.S. Code of Federal Regulation as a food additive, and is authorized for use in both paper and plastic food contact appHcations. 

Labels for soft drink bottles, shampoo bottles, plastic food containers and the like, require high adhesion to materials like polyester and polyolefins. Once applied, the adhesive may have to withstand repeated flexing, freezing, water and other fluid spillage, while maintaining aesthetic appearance. 

Odor and taste Polystyrene, styrene-acrylonitrile, polyethylene, acrylic, ABS, polysulfone, EVA, polyphenylene oxide, and many other TPs are examples of satisfactorily odor-free. FDA approvals are available for many of these plastics. Food packaging and refrigerating conditions will also eliminate certain plastics. There are TPs and melamine as well as urea compounds that are suitable for this service.

Plastic food wrappers may be printed with pigments that contain lead chromates. Plastic wrappers used for 14 different national brands of bread collected in New Jersey contained a mean concentration of 26 mg of lead for a bag size of 2,000 cm2. A survey of 106 homemakers who buy such breads indicated that 39% of them reused the bags and 16% of the respondents turned the bags inside out to reuse them, suggesting that the potential exists for lead leaching from the paint into the stored food (Weisel et al. 

Three Ciba HALS stabilisers are currently approved for use in plastic food-contact materials in Europe (Directive 2002/72/EC, Plastic materials and articles used in contact with food.) These are Chimassorb 944, Tinuvin 622 and Chimassorb 2020. Their chemical structures are given in Figures 31-33, respectively.

Polyacrylonitrile plastic bottles for soft drinks and beer were taken off the market as possible carcinogens because of migration of acrylonitrile into the drink. Now most plastic food containers of this type are poly(ethylene terephthalate).

Tin can also combine with carbon-containing materials to form organotin compounds. These compounds are used in making plastics, food packages, plastic pipes, pesticides, paints, wood preservatives, and rodent (rats and mice) repellents. 

Numerous nonplasticizer uses of DEHP have been reported however, it is not clear to what extent these uses are, or have ever been, important. Because of concerns regarding potential health effects from DEHP exposure, many toy manufacturers have discontinued use of DEHP in their products. The use of DEHP in domestically produced baby teethers and rattles has been discontinued, and DEHP is also no longer used as a plasticizer in plastic food wrap products. 

Butane is found in exhausts of gasoline engines and in waste disposal sites. Butane as a gas is highly inflammable and explosive pure butane has several applications in industries and processing associated with aerosol propellants, fuel source, solvents, rubber, plastics, food additive, and refrigeration. Occupational exposure to liquefied butane by direct contact results in severe adverse effects (e.g., bums or frostbite to skin, eyes, and mucous membrane, as well as CNS depression).

Three different approaches have been presented for estimating the partitioning of solutes between plastics and liquids. In the context of evaluating the output from these different approaches it is also useful to define the expected experimental ranges and limits for partition coefficients based on the solutes, plastic and contacting liquid phases involved. Table 4-9 shows approximate upper and lower limits for partition coefficients one may normally encounter in plastic/food systems based on the polarities of the solutes, plastics and foods. The table also gives approximate ranges of partition coefficient values for various solutes between typical food contact plastics and liquid phases.
