#1 Polyethylene Terephthalate (PETE or PET): No known hazards.

#2 High Density Polyethylene (HDPE): No known hazards.

#3 Polyvinyl Chloride (PVC or vinyl): Plasticizers are added to many PVC products to make them flexible. These include phthalates — suspected endocrine-disrupting chemicals (EDCs). DEHA, another possible endocrine disruptor, was found to leach from PVC cling wraps into cheese in 1998 tests by Consumer Reports. Grocery stores commonly use PVC to wrap deli meats and cheeses. Reynolds cling wrap is PVC. Appalachian Mountain spring water and some vegetable oils are bottled in PVC. And PVC’s manufacture and incineration produces highly toxic dioxins, as does the PVDC used in Saran Wrap, according to Consumers Union, publisher of Consumer Reports.

#4 Low Density Polyethylene (LDPE): No known hazards.

#5 Polypropylene (PP): No known hazards.

#6 Polystyrene (PS or Styrofoam): Made from styrene, a suspected carcinogen, PS also contains p-nonylphenol; both chemicals are suspected EDCs. Do not consume fatty foods or alcoholic beverages from Styrofoam containers; styrene can leach into these substances. Some opaque plastic cutlery is PS, as well.

#7 Other Resins, including Polycarbonate (PC): Most clear plastic baby bottles and 5-gallon water bottles are made of PC. Bisphenol-A, an EDC in PC, has been found in water and heated infant formulas bottled in PC, as well as food cans lined with a plastic film.
