The material of plastic container marks in general, the sign of plastic containers are at the bottom, there is a triangle symbol, the triangle is punctuated with number 1 to 7, with each number represents a kind of plastic containers, because they are the difference of the material, so the use of taboo there are also different. Is roughly: the numbered '1', for the common water bottles, bottle carbonate etc, heat to 70 ℃ is easy deformation, have RongChu harmful substances to human body, with 10 months later, can release carcinogens; Marked number '2' for detergent, shampoo, shower gel, edible oil, pesticide and so on container to use, not used as water glass, or do other goods storage containers, do not use cycle; Marked number '3', how to make water pipe, raincoat, bag, building materials, plastic film, plastic boxes, and so on implements, plasticity is good, the price is cheap, easy to bad material at high temperature, is seldom used in cosmetics packaging; Marked with number '4', and more used in the manufacture of the ubiquitous plastic bottles, high temperature sometimes produce harmful substances, have poison after food enters the human body, may cause diseases such as breast cancer, birth defects; Marked with number '5', how to make the bucket, dustbin, laundry list, basket and microwave oven with food containers, etc. , can be as high as 167 ℃, melting point is the plastic box can be put into the microwave, can be reused after careful cleaning; Marked with number '6', because of the low water imbibition, how to make building materials, toys, stationery, roller, and fill the cup box or disposable tableware in fast food restaurants, avoid using such a snack box packaging hot food, don't use the microwave oven cooking bowl of instant noodles; Marked with number '7', commonly used such material manufacturing such as kettle, space cup, bottle, etc. Try not to use disposable tableware although some companies in environmental protection tableware, starch based tableware or the guise of degradable tableware and the quality of the product but there are a lot of potential safety problems, the reality is degradable tableware not degradation, environmental boxes environmental problem is severe, it will bring serious hidden danger to the health of consumers. When consumer is using the disposable tableware, unknowingly eat into his stomach has not only the food, there are snack box of plastic, paraffin and stone powder. Besides the purchase and the use of disposable tableware, will let these one-off things directly into the garbage, not only waste resource, but also damage the environment, is not very 'green' consumption. Low temperature heating bottle problem is plastic (poly (ethylene terephthalate PET) Is used for water bottles, bottle materials such as carbonated bottle, the heat to 65 ℃, cold tolerance to - 20 ℃, and suitable for the drink warm or room temperature. According to the survey, the convenience store in the temperature of the heating cabinet more control under 50 ℃. Therefore, low heat, don't worry too much about bottled drink has a plasticizer. Plastic heating was really easy deformation, studies have reported 10 months after continuous use, may release the plasticizer, so don't used as a water container. Online also have reported, bottled water exposure in the car, will produce harmful material such as plasticizer, but in recent years the domestic related research has confirmed that a complete package of bottled water is no plasticizer exhalation inside 7 days of exposure, the total number of colonies did not see obvious changes. But, if it's open a bottle of drinking bottled water, because the bacteria to enter the outside world, under the condition of high temperature, easily lead to bacterial growth. Paper packaging bottles whether 'foam' security hidden danger are big disposable polystyrene foamed plastic tableware is banned to use in our country. However, disposable polystyrene foam tableware whether, if use temperature over 90 ℃, or in the microwave, will precipitate harmful substances. In addition, disposable plastic tableware also contain carcinogenic fluorescent material, these are buried unsafe hidden danger to the health of the consumer. Cosmetics of poisonous and harmful substances, the harm of human body and the environment is a chronic, usually may feel ok, long-term, gradually accumulated, once something is is too late to regret.
