Okay I found this.

First of all, the plastic bottles and containers that are used for packaging food should all be labeled with a recycle code.(below)
This is a number (between 1 and 7) that is surrounded by a small graphic of three arrows pointing at one another in a triangle. These numbers tell the recycle center what kind of plastic the container is made of and they also tell the consumer whether there is a known potential health hazard.
Bear in mind that simply because there is a known "potential" health hazard, it does not mean that you are going to be immediately ill if you find you have been using a product in that category.
In fact, for some of the chemicals to leach out of these "dangerous" plastics, the container must have been heated with the food or liquid inside; sometimes the level of heat required is greater than the boiling point. However, we should all be aware of what we are using and what it may mean. Likewise, simply because there are no "known" health hazards does not mean that a plastic is always going to be completely safe under all conditions. The point here is not to frighten, simply to remind us that when dealing with artificial chemical products we must always be open-minded and educated.

The following plastics have no known health hazards:
Code 1: Polyethylene Terephthalate, or PET / PETE

Code 2: High Density Polyethylene, or HDPE

Code 4: Low Density Polyethylene, or LDPE

Code 5: Polypropylene, or PP

The following plastics do have known potential health hazards:

Code 3: Polyvinyl Chloride, or PVC / Vinyl. This material, used often in flooring and shower curtains, as well as household water pipes (primarily for evacuation only - they should never be used to bring fresh water into the home), used to be used in cling wraps. The plastics industry is adamant that the type of PVC currently used in cling wraps does not contain the phthalates that are known endocrine disrupters. However, these phthalates may still be present in PVC bottles and toys. There was recent information that many baby teethers were also made from PVC, due to its soft flexibility. PVC or vinyl items should never be given to a baby or child who may put them in his or her mouth.

Code 6: Polystyrene, or PS / Styrofoam. As well as being another endocrine disrupter, styrene is also believed to be a carcinogen. This plastic is used to make some types of disposable forks, spoons and knives and also the "foam" cups such as those sold under the name Styrofoam. Hot liquid can cause the styrene to leach out of these products, as can fatty oils or alcohol.

Code 7: Other "resins" and Polycarbonate, or PC. This one has been hotly contested by the plastics industry because of the high heat required for the endocrine disruptor, Bisphenol - A (BPA), to be released. However, BPA is a primary component of PC plastics and is a verifiably dangerous compound. PC is largely used for water bottles of the type used for delivery services (multi-galon containers) that fit on the "water cooler" at home or office. Many clear baby bottles are made of PC and there is much in the news about the controversy of these bottles not being labled with any code so that consumers cannot tell what type of plastic is used. With baby bottles, this is a real concern, as many people boil the bottles with formula or milk inside them. PC is also used in food cans with a plastic lining. Whenever possible, it is recommended that these plastics not be exposed to high temperatures. The plastics industry insists that they are completely stable under most conditions but some studies suggest that leaching still occurs.

Okay I don't know what had strucked me.
But I feel so inferior suddenly .
Everything happening are evidences.

Confused.
Can you don't put up a strong front?
Can you show me your real feelings?
Ah _|_

Simply no one.

Wait wait wait.
How long?
I deserve this.
