There are digital signs under the plastic products, as follows:
1, number 1
PET (Polyethylene Terephthalate), a container made of this material, is a common plastic bottle for soda, also known as "Bote bottle".
Common mineral water bottles, carbonated beverage bottles, etc. Heat resistance to 70℃ is easy to deform, and substances harmful to human body are melted out. 1 Plastic products may release carcinogen DEHP after long-term use. Can't put it in the car to bask in the sun; Don't pack alcohol, oil and other substances.
Step 2: the second one
HDPE (High Density Polyethylene), containers for detergents, shampoos, bath milk, edible oil, pesticides, etc. Most of them are made of high density polyethylene. Most containers are opaque and feel like wax.
Common white medicine bottles, cleaning products, bath products. Don't use it as a cup, or as a storage container for other items. If the cleaning is not thorough, don't recycle it.
Step 3: the third one
PVC (polyvinyl chloride) is mostly used to make water pipes, raincoats, schoolbags, building materials, plastic films and plastic boxes.
Common raincoats, building materials, plastic films, plastic boxes, etc. Excellent plasticity and low price, so it is widely used, and can only resist heat of 865438 0℃. It is easy to produce harmful substances at high temperature and is rarely used in food packaging. It is difficult to clean, and it is easy to remain, so don't recycle it. Don't buy packaged drinks.
Step 4: the fourth one
LDPE (Low Density Polyethylene), a plastic bag that can be seen everywhere, is mostly made of LDPE.
Common cling film, plastic film, etc. Harmful substances will be produced at high temperature, and toxic substances may cause diseases such as breast cancer and birth defects of newborns after entering the human body with food. Don't put plastic wrap in the microwave.
5, the number 5
PP (polypropylene) is mostly used to make food containers for buckets, trash cans, laundry baskets, baskets and microwave ovens.
Common soybean milk bottles, sour milk bottles, fruit juice bottles, microwave lunch boxes. It can withstand the high temperature of 167℃, and it is the only plastic box that can be put into the microwave oven. It can be reused after careful cleaning. It should be noted that the material of some microwave lunch boxes is No.5 PP, but the lid is No.4 PE. Because PE is not resistant to high temperature, it can't be put in the microwave oven with the box.
6. Number 6
PS (polystyrene), because of its low water absorption, is mostly used to make building materials, toys, stationery, rollers, and cups or disposable tableware for drinks in fast food restaurants.
Common instant noodle boxes and fast food boxes in bowls. Can't put it in the microwave oven, so as not to release chemicals when the temperature is too high. After being filled with acid (such as orange juice) and alkaline substances, carcinogens will decompose. Avoid packing hot food in fast food boxes. Don't cook bowls of instant noodles in the microwave oven.
No.7.7
Others. Common PC, such as kettle, space cup, milk bottle, etc. Department stores often use this kind of water cup, PA, that is, nylon, which is mostly used in fiber textiles and some household appliances and other internal products. At high temperature, PC can easily release bisphenol A, a toxic substance harmful to human body. Don't heat it when using it, and don't directly bask in the sun.
Extended data
A Method for Identifying Polypropylene, Polyethylene and Polycarbonate —— Combustion Method
According to the color of the flame and the smell and smoke when burning plastics, the flame of polyolefin raw materials is usually blue or light blue, with mild and light smell and white smoke, while most raw materials containing benzene or chlorine are prone to black smoke and strong smell after burning, so ABS is it.
In addition, for example, PE and PP have dripping phenomenon, while PVC has no dripping phenomenon, but it has self-extinguishing phenomenon.
