What do the different numbers molded into plastic containers mean?

The code numbers, along with their respective types of plastics and most common uses are as follows: • #1 PETE (polyethylene terephthalate) soda and beverage bottles; also mouthwash bottles, peanut butter jars and some spice and ketchup bottles. • #2 HDPE (high density polyethylene) usually milk and water jugs, detergents, bleaches and cleaners • #3 PVC (polyvinyl chloride) telephone cable, floor mats, irrigation pipe, truck bed liners, garbage cans • #4 LDPE (low density polyethylene) trash bags, grocery bags, fiberfill for pillows, pipe, plastic lumber • #5 PP (polypropylene) carpet backing, auto battery cases, video cas
