General plastic products above some symbol of the triangle is recycling, there is a number, here is the PP or PE. It's like every plastic container id, their material is different, have different use.

The meaning of the Numbers represent

"01" -- PET (polyethylene terephthalate) bottles, carbonated beverage bottles are made of this material. Dong jinshi pointed out that the bottles can't cycle using hot water, heat to 70 ℃, this material is only suitable for the warm drink or beverage, with high temperature liquid or heating is easy to deformation, are harmful to human body material dissolution. Also, scientists have found that this kind of plastic products used for 10 months after the may release carcinogens, toxic to the human body. Ran out of bottles and so on, therefore, was to lose, don't be used as a water bottle, or used to make containers holding other items, so as not to cause health problems.

"02" - HDPE (high density polyethylene) bearing cleaning supplies, bath products of plastic containers, the use of plastic bags in supermarkets and shopping malls are made this kind of material, resistant to high temperature of 110 ℃, indicating the food with plastic bags can be used for holding food. Guangdong cleaning supplies, bath products of plastic containers can be reused after careful cleaning, but these containers are usually not good cleaning, residual original cleaning products, become a hotbed of bacteria, clean is not complete, it is best not to recycle.

"03" - PVC (polyvinyl chloride) according to introducing, this kind of material of the plastic products easy generation of toxic and harmful substances from the two aspects, one is the production process is not fully single molecule vinyl chloride polymerization, plasticizer of pests. When the two substances in case of high temperature and oil easy to precipitate, toxicant after food enters the human body, easy to cause cancer. At present, this kind of material has been less used in packing food container. If you are using, don't let it is heated.

"04" -- LDPE (low density polyethylene), cling film, plastic film, etc. Is this kind of material. Heat resistance is not strong, usually, the qualified PE cling film hot melt phenomenon occurs on the temperature over 110 ℃, can leave some of the human body cannot decompose plastic preparation. And, heating food with plastic wrap, the fat in food is easy to dissolve the harmful material in plastic wrap. Therefore, food into the microwave oven, to remove the wrapped in plastic wrap.

"05" - made from PP (polypropylene) microwave boxes with this kind of material, resistant to high temperature of 130 ℃, transparency is poor, this is the only plastic box can be put into the microwave, reusable after careful cleaning. Need to pay special attention to is that some of the microwave oven, the box body to 05, PP, but the lid to 06 # PS (polystyrene)) manufacturing, PS good transparency, but not high temperature resistant, so can't together with the box body into the microwave oven. To be on the safe side, before the containers in the microwave oven, first remove the lid.

"6" - PS (polystyrene) which is used in the manufacture of bowl of instant noodles boxes, foamed snack box materials. Heat and cold, but not into the microwave oven, so as not to release chemicals because the temperature was too high. And cannot be used for holding acid (such as orange juice), strong alkaline substances, because will break down the polystyrene is bad for the body. Therefore, you should avoid to use snack box packaging hot food.

"7" - PC and other type of PC is used by A large number of A material, especially used in the manufacture of bottles, space cup, etc., more controversial because of containing bpa. Experts point out that, in theory, as long as in the process of production of PC, bisphenol A hundred into plastic structure, then said products without bisphenol A, not to mention release. Only, if there is A small amount of bisphenol A is not converted into PC plastic structure, which may be released into the food or drink. Therefore, when using the plastic containers should be attention.

Traces of bisphenol A in the PC, the higher the temperature, the more release, the faster the speed. Therefore, should not be to PC bottle of hot water. If your kettle number is 7, the following methods can reduce the risk: do not heat when using, do not in direct sunlight. No, the bowl of dryer clean kettle dishwasher. Before first use, use baking soda wash with warm water, natural drying in room temperature. If there are any hurt or damaged container, we suggest to stop using, because plastic products surface if slightly grooved, bacteria easy to hide. To avoid repeated use of already aging plastic utensils.

The following are some of the common plastics, they may not have any recycling id code, but still has the collection value. Most recyclers will accept these items, so if you happen to have these plastic. Please make sure they can be recycled.
