Many of us are moving to green now-a-days and often its a challenge to find some alternatives to the plastics that we use. Following is the description of the Types of plastics and how good/bad they are. Hope this helps in conscious choice.

1. PETE: Polyethylene terephthalate ethylene used for soft drink, juice, water, detergent, cleaner and peanut butter containers. It was considered the safest and is the most common plastic and easy to recycle. However, a recent study found traces of DEHP in bottled water stored in a PET bottle for more than 9 months.
2. HDPE: High density polyethylene, used in opaque plastic milk and water jugs, bleach, detergent and shampoo bottles and some plastic bags. It is considered safe and easy to recycle.
3. PVC or V or DEHA : Polyvinyl chloride or di(2-ethylhexyl)adipate used for cling wrap, some plastic squeeze bottles, cooking oil and peanut butter jars, detergent and window cleaner bottles. PVC is well known to be associated with liver cancer. DEHA is linked to negative effects on the liver, kidney, spleen, bone formation and body weight. It is the least recyclable.
4. LDPE: Low density polyethylene, used in gro­cery store bags, most plastic wraps and some bottles. It is considered safe but hard to recycle.
5. PP: Polypropylene, used in most Rubbermaid, deli soup, syrup and yogurt containers, straws and other clouded plastic containers, including baby bottles. It is considered safe but hard to recycle.
6. PS: Polystyrene, used in Styrofoam food trays, egg cartons, disposable cups and bowls, carry-out containers and opaque plastic cutlery. Styrene can leach from polystyrene and is toxic to the brain and nervous system. It also has been found to affect red blood cells, liver, kid­neys and stomach in animal studies. It is hard to recycle.
7. Other: Usually polycarbonate, used in most plastic baby bottles, 5-gallon water bottles, “sport” water bottles, metal food can liners, clear plastic “sippy” cups and some clear plastic cutlery. New bio-based plastics may also be labeled #7. Polycarbonate can leach Bisphenol A, a chemical that mimics the action of the human hormone estrogen. It was found to stimulate prostate cancer, produce ovarian dysfunction, genetic damage, etc. (see Baby Bottles free of BPA).
