There are 1-7 numbers in the triangle at the bottom of the plastic beverage bottle, and pet words below. What does it mean?

by admin

there is an Arabic numeral in the recycling triangle at the bottom of the plastic bottle. In fact, it represents the material of the container:

1 – represents that pet (polyethylene terephthalate) can be used to produce mineral water bottles and carbonated beverage bottles. It is heat-resistant to 70 ° C and changeable. Substances harmful to human body dissolve out. It may release carcinogen DEHP after long-term use. Therefore, it cannot be used to hold wine, vinegar, soy sauce, etc

2 – represents that HDPE (high density polyethylene ester) is mostly used in cleaning products and bath products. It is resistant to high temperature, but it is not easy to clean and should not be recycled

3 – represents PVC (polyvinyl chloride), which is used in raincoats, building materials, plastic boxes, etc., and rarely used in food packaging

4 – represents that LDPE (low density polyethylene) is used for fresh-keeping film and plastic film. It has weak heat resistance and will produce harmful substances at high temperature

5 – represents PP (polypropylene), which is mostly used in plastic boxes that can enter the microwave oven. It can be reused after careful cleaning

6 – represents PS (polystyrene), which is used to make bowl instant noodle boxes, fast food boxes, etc., and cannot be used for microwave heating, strong acid (orange juice) and strong alkaline substances. Avoid holding hot food

7 — PC (polycarbonate) and other types are mostly used to make milk bottles, space cups, etc. try not to use it to hold boiling water, otherwise it is easy to release toxic substances. Do not heat it when using it and do not directly bask in the sun

extended data:

use safe plastic products:

in order to ensure our health, we need to choose to use safe plastic products in our daily life. Consumers should pay attention to whether the information in the product label is complete, including the manufacturer, production license number, executive standard, material, etc., when buying plastic drinking cups, Nanjing Daily reported

among them, the materials of all parts that may contact food should be listed in detail, including cup cover, cup body, straw, etc. Experts suggest that plastic food containers, including children’s plastic drinking cups, try to choose PP material

in addition, consumers should try to avoid using plastic containers or plastic bags to put hot water, hot soup, tea and coffee, and avoid heating food in non special plastic containers in the microwave oven

reference source: People’s Network – will drinking plastic bottled water in daily life be harmful to your body

Pet polyethylene terephthalate in standard 1
common mineral water bottles, carbonated beverage bottles, etc. Heat resistant to 70 ℃, easy to deform, and substances harmful to human body melt out. No. 1 plastic may release carcinogen DEHP after 10 months of use. Do not put it in the sun in the car; Do not pack alcohol, oil and other substances

standard 2
HDPE high density polyethylene
common white medicine bottles, cleaning products and bath products. Don’t use it as a water cup or as a storage container for other items. Do not recycle if the cleaning is not complete

standard 3
PVC
common raincoats, building materials, plastic films, plastic boxes, etc. Excellent plasticity and low price, so it is widely used. It can only resist heat at 81 ℃ It is easy to produce bad substances at high temperature and is rarely used in food packaging. Difficult to clean, easy to residue, do not recycle. Don’t buy drinks

PE PE in standard 4
common fresh-keeping film, plastic film, etc. When high temperature has harmful substances, toxic substances enter the body with food, which may cause breast cancer, neonatal congenital defects and other diseases. Don’t put plastic wrap in the microwave

PP in standard 5
polypropylene
common soymilk bottles, yogurt bottles, fruit juice beverage bottles and microwave oven lunch boxes. Melting point up to 167 ℃, it is the only plastic box that can be put into the microwave oven and can be reused after careful cleaning. It should be noted that for some microwave oven lunch boxes, the box body is made of No. 5 PP, but the box cover is made of No. 1 PE. Because PE cannot withstand high temperature, it cannot be put into the microwave oven together with the box body

PS polystyrene in
standard 6
common bowl instant noodle boxes and fast food boxes. Do not put it in the microwave oven to avoid releasing chemicals due to excessive temperature. After containing acid (such as orange juice) and alkaline substances, carcinogens will be decomposed. Avoid packing hot food in fast food boxes. Don’t cook a bowl of instant noodles in the microwave

standard 7
other types of PC
common kettle, space cup and milk bottle. Department stores often use water cups made of this material as gifts. It is easy to release toxic substance bisphenol A, which is harmful to human body. Do not heat when using, do not directly sun in the sun

generally, there are 1 ~ 7 numbers in the triangle at the bottom of the plastic container (plastic product recycling identification). Each number represents a kind of plastic container. They are made of different materials and different taboos in use

the recycling label of plastic products is formulated by relevant institutions of the plastic industry in the United States. This set of signs marks the plastic material identification code on the container or package, from No. 1 to No. 7, so that people can simply join the recycling work without bothering to learn the similarities and differences of various plastic materials

No. 1: pet (polyethylene terephthalate), a container made of this material, is a common plas
tic bottle containing soda, also known as “Baote bottle”

No. 2: HDPE (high density polyethylene). Containers for detergents, shampoos, shower creams, edible oils, pesticides, etc. are mostly made of HDPE. Containers are mostly opaque and feel like wax

No. 3: PVC (polyvinyl chloride), which is mostly used to make water pipes, raincoats, schoolbags, building materials, plastic films, plastic boxes and other utensils
> made of low density polyethylene (LDPE) bags, which can be seen everywhere

No. 5: PP (polypropylene), which is mostly used to make buckets, garbage cans, baskets, baskets and food containers for microwave ovens

No. 6: PS (polystyrene), due to its low water absorption, is mostly used to make building materials, toys, stationery, rollers, as well as cup boxes or disposable tableware for drinks in fast food restaurants

No. 7: others.
PET /
is specially made for carbonated drinks.
