Number 1 Plastics -- PET or PETE (polyethylene terephthalate)

* Found In: Soft drinks, water and beer bottles; mouthwash bottles; peanut butter containers; salad dressing and vegetable oil containers; ovenable food trays.

It poses low risk of leaching breakdown products.

Number 2 Plastics -- HDPE (high density polyethylene)

* Found In: Milk jugs, juice bottles; bleach, detergent and household cleaner bottles; shampoo bottles; some trash and shopping bags; motor oil bottles; butter and yogurt tubs; cereal box liners

HDPE carries low risk of leaching and is readily recyclable into many goods.

Number 3 Plastics -- V (Vinyl) or PVC

* Found In: Window cleaner and detergent bottles, shampoo bottles, cooking oil bottles, clear food packaging, wire jacketing, medical equipment, siding, windows, piping

PVC contains chlorine, so its manufacture can release highly dangerous dioxins. If you must cook with PVC, don't let the plastic touch food. Never burn PVC, because it releases toxins.

Number 4 Plastics -- LDPE (low density polyethylene)

* Found In: Squeezable bottles; bread, frozen food, dry cleaning and shopping bags; tote bags; clothing; furniture; carpet

Generally considered safe.

Number 5 Plastics -- PP (polypropylene)

* Found In: Some yogurt containers, syrup bottles, ketchup bottles, caps, straws, medicine bottles

Polypropylene has a high melting point, and so is often chosen for containers that must accept hot liquid. Generally considered safe.

Number 6 Plastics -- PS (polystyrene)

* Found In: Disposable plates and cups, meat trays, egg cartons, carry-out containers, aspirin bottles, compact disc cases

Polystyrene can be made into rigid or foam products -- in the latter case it is popularly known as the trademark Styrofoam. Evidence suggests polystyrene can leach potential toxins into foods. The material was long on environmentalists' hit lists for dispersing widely across the landscape, and for being notoriously difficult to recycle.

Number 7 Plastics -- Miscellaneous

* Found In: Three- and five-gallon water bottles, 'bullet-proof' materials, sunglasses, DVDs, iPod and computer cases, signs and displays, certain food containers, nylon

A wide variety of plastic resins that don't fit into the previous categories are lumped into number 7. A few are even made from plants (polyactide) and are compostable. Polycarbonate is number 7, and is the hard plastic that has parents worried these days, after studies have shown it can leach potential hormone disruptors.
