there are lots of studies going on now noting the chemical residues that leach into food products that are stored in plastics. the chemicals in plastics ARE NOT GOOD FOR YOU. lucky for us, most food is packaged and stored in plastics. hmph.
"These chemicals include suspected carcinogens or endocrine disruptors, which have been linked to reproductive system harm." fun stuff....
so, better safe than sorry, these tests are still going on, tyr as much as possible to store food in glass or steel containers. plastic sucks for the earth anyway, it doesnt go away, its time to stop with the plastic craze. more companies are starting to use glass as a packaging alternative.
the greenguide site lists that ziplock bags are "safe", still nonbiodegradable methinks, but safe for ur food. they also have a comprehensive list of which plastics do the most and least harm. THE LIST IS SORTED BY WHICH NUMBER THE PLASTIC IS RECYCLED BY, SO PAY ATTENTION TO THE NUMBERS WHEN BUYING FOOD. i read that industrial grade plastic wrap [deli wrap] has more pvc's in it, and food should be taken out ASAP. the same source said that glad wrap [home use] is safer, dunno why tho.
#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.
