Drink water from plastic bottles. What kind of plastic bottle can receive hot water?

When the weather is hot, many people like to use plastic bottled water, but sometimes they think the water smells bad, so they continue to use plastic bottled water for convenience. Some people think it has something to do with a sign on the plastic bottle: in the triangle composed of three arrows, there is the number 1-7. The bigger the number, the more heat-resistant the bottle is. But is it really that the bigger the number, the more heat-resistant it is? Won't it be harmful to people's health

"recyclable" sign

The triangle formed by three arrows is a sign of "recyclability". The recycling label of plastic products is formulated by the relevant institutions in the plastic industry in the United States. This set of signs puts the plastic material identification code on the container or package, fromNo. 1 to No.7, so that people can simply join the recycling work without having to bother to understand the similarities and differences of various plastic materials. Every plastic container has a small ID card-a triangular symbol, usually at the bottom of the plastic container. There are 1 ~ 7 numbers in the triangle, and each number represents a plastic container. They are made of different materials and have different taboos when using them:

No. 1: PET (polyethylene terephthalate). The container made of this material is a common plastic bottle for soda, which is also commonly 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. Plastic product 1 may release carcinogen DEHP after using 10 months. Can't put it in the car to bask in the sun; Don't pack alcohol, oil and other substances. It may dissolve some substances harmful to human body. Don't put mineral water in the open air or in the car in hot weather, and don't flush boiling water directly into coke bottles.

Second: 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. Previously, plastic bags widely used in supermarkets and shopping malls all used this material, which is relatively resistant to high temperature, but it is not easy to clean and easy to breed bacteria;

Third place: PVC (polyvinyl chloride) is mostly used to make water pipes, raincoats, schoolbags, building materials, plastic films, plastic boxes and other utensils.

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. Among them, plasticizer contains harmful substances, which are easy to precipitate when exposed to high temperature and oil. At present, many plasticizers have been banned in Europe, and plastic products used for packaging food are rarely used in China.

Fourth place: LDPE (low density polyethylene). Plastic bags are everywhere, 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. At present, most fresh-keeping films and plastic films on the market are made of this material, and their heat resistance is not strong. When the temperature of qualified PE plastic wrap exceeds 1 10℃, hot melting will occur. When food is wrapped in plastic wrap and heated, the oil in food will easily dissolve the harmful substances in plastic wrap.

Fifth place: 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. With a melting point as high as 167℃, it is the only plastic box that can be put into a microwave oven and can be reused after careful cleaning. It should be noted that some microwave lunch boxes are made of No.5 PP, but the cover is made of 1 PE. Because PE is not resistant to high temperature, it can't be put in the microwave oven with the box. The microwave lunch box is made of this material, which is resistant to high temperature 130℃ and has poor transparency. Some lunch boxes are made of PP, but the lid is made of PS (polystyrene), which has good transparency, but it is not resistant to high temperature, so it can't be put into the microwave oven with the box.

6 th place: PS (polystyrene), because of its low water absorption, is mostly used to make building materials, toys, stationery, rollers, and cups or disposable tableware for 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. )

Seventh: others. Common kettles, space cups and milk bottles. Department stores often use cups made of this material as gifts. It is easy to 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.

So I suggest you try not to use plastic bottles of boiling water!
