Plastic recycling symbol with secret teach you recognize whether toxic plastic water bottles

Plastic recycling symbol as the id, the triangle frame Numbers ranging from 1 to 7, behind each number represents a kind of specifications of plastic containers, meaning not the same. Want to know that their own drinking water have non-toxic plastic bottles? With below small make up together and see it.

"01" drink is lost

"01" on behalf of the PET (polyethylene terephthalate), the most commonly used to make bottled drinks such as mineral water, carbonated drinks and so on. As it is known that beverage bottle made of this material can't install hot water, only suitable for the warm drink or beverage, with high temperature liquid or heating is easy to deformation, dissolution substances harmful to human body. Scientists also found that the plastic products to use after more than 10 months, may release the carcinogens. So suggest drank bottles is lost, don't be used as a water cup, or containers. So as not to cause a harm to health, do more harm than good.

Not recommended for water appliance "02"

"02" on behalf of HDPE (high density polyethylene), equipped with cleaning supplies, bath products, plastic containers, or in the mall general more plastic bags is made of this material. Resistant to high temperature of 110 ℃, if the mark is used in the food can be used for holding food. Cleaning supplies, bath products of plastic containers can be reused after careful cleaning, but because of bad cleaning, leave a residue, thus become a hotbed of bacteria. Such as post mentioned, is different from other beverage bottle, 4 l of nongfu spring is marked at the bottom of the 02. Although look than the average water bottles a lot, but it's not suggested to do water equipment, long-term use of harmful material to produce the possibility is very large.

"03" don't let it is heated

"03" on behalf of PVC (polyvinyl chloride), common in raincoat, plastic film. Made of the material of the plastic products are prone to two kinds of poisonous and harmful material: one is the production of single molecule is not fully in the process of polymerization of vinyl chloride, the second is the harmful material in plasticizer. When the two substances in case of high temperature and oil easy to precipitate, if inadvertently enter human body, easy to cause cancer. It is rarely used in food packaging, if happened to meet, don't let it is heated.

"04" can appear more than 110 ℃ hot melt phenomenon

"04" namely LDPE (low density polyethylene), cling film, plastic raw materials, heat resistance is not strong. Qualified PE cling film hot melt phenomenon occurs on the temperature over 110 ℃, leaving some of the human body cannot decompose plastic preparation. And if wrapped in food external heating at the same time, the fat in food is more easily dissolved the harmful substances in cling film.

"05" caution can be reused after cleaning

"05" on behalf of PP (polypropylene), which is the only material that can be heated in the microwave, so become the production of microwave boxes of material. Resistance to high temperature of 130 ℃, melting point 167 ℃, transparency is poor, can be reused after cleaning. It is important to note that some of the microwave oven, the box body to 05, PP (polypropylene) manufacturing, but lifted the lid to 06 # PS (polystyrene)) manufacturing, PS good transparency, but not high temperature resistant, so can't into the microwave oven with the box body. After heating boxes before, don't forget to take off the lid.

"6" direct heating bowl of instant noodles boxes of avoid by all means

"6" or PS (polystyrene), which is used in the manufacture of bowl of noodles box, the material of foamed snack box. Cannot be used for holding acid (such as orange juice), strong alkaline substances, because will break down the bad for the body of polystyrene (carcinogens). Although the heat resistance and cold resistance, but also release chemicals because the temperature was too high, so don't directly in the microwave heating bowl of instant noodles!

"7" be careful to use, can avoid "bisphenol A"

"7" on behalf of the PC and other types of PC, is used by A large number of A kind of material, used in the manufacture of bottles, space cup, etc., more controversial because of containing toxic bisphenol A. In theory, as long as in the process of production of PC, bisphenol A has been converted into one hundred percent plastic structure, then said products without bisphenol A, not to mention release. But no one can guarantee the bisphenol A has been completely transformed, in use process need to pay attention to.

Bisphenol A, the higher the temperature the more release, the faster the speed. If you happen to have an Numbers for 07 plastic products, the following methods can be used to avoid: do not heat when using, do not in direct sunlight; Without the dishwasher, the bowl of dryer clean water; Before first use, use baking soda wash with warm water, natural drying in room temperature; If there are any hurt or damaged containers, and stop using immediately, because if slightly grooved plastic products surface, easy to hide bacterium; To avoid repeated use of already aging plastic utensils.

Experts suggest that

In daily life, beverage bottle, mineral water bottles, the repeated use of the phenomenon is very common. Many consumers tend to like their used, beverage bottle, mineral water bottles to fill up again the next time you go out the tea or water out of the door, called it "environmental protection", "save". , experts say, qualified beverage bottle, mineral water bottles were required to be made, food-grade plastic or PET bottles. These food grade PET bottle is not capable of high temperature, need to be used in low temperature, in 70 degrees commonly the following use is safe. In addition, these plastic bottles are one-time use, the provisions of the state enterprise is unable to recycle and repeat filling used.

Plastic bottles have a plasticizer is added in the production process, and the chemicals are toxic to the human body, if use plastic bottled water for a long time, such as oil and wine, easy to internal harmful material dissolution, so as to bring into the body. He suggested that the use of the material such as glass, stainless steel bottle food, is relatively safe.
